  • 00:00:00
    okay so I'm going to walk everybody
  • 00:00:03
    through a full six meter cycle here
  • 00:00:08
    obviously starting with the muck pile I
  • 00:00:11
    did not have actually footage of gassing
  • 00:00:16
    out and washing down washing down is of
  • 00:00:19
    course important you know keep the gases
  • 00:00:21
    down and I like to clean all my hoses
  • 00:00:23
    and everything under the header and it
  • 00:00:24
    makes it look nice so we're going to go
  • 00:00:26
    straight to making this muck pile
  • 00:00:27
    disappear and get into some some other
  • 00:00:31
    action here so this is a 6 meter round
  • 00:00:35
    eight point one by eight point three
  • 00:00:38
    usually about 140 blast holes and in
  • 00:00:42
    this time-lapse we were four reamers and
  • 00:00:47
    later on we switched to six and
  • 00:00:49
    eliminated all bootlegs like he was just
  • 00:00:53
    button marks every day so this is the
  • 00:00:56
    scalar rolling in big mechanized scaler
  • 00:00:59
    we got took a lot of the hand labor and
  • 00:01:03
    in doing this and certainly made it a
  • 00:01:05
    lot safer for everybody rather than
  • 00:01:07
    sending a couple of guys under a covered
  • 00:01:10
    man basket to take all this down by hand
  • 00:01:14
    we just had my my partner here going
  • 00:01:18
    with this little girl here and take down
  • 00:01:22
    every little chunky could get his little
  • 00:01:24
    pic under and I see him go over he goes
  • 00:01:34
    over the entire round and gives the face
  • 00:01:36
    of scrape to and because in the next
  • 00:01:39
    clip I'm going to be sending him in
  • 00:01:41
    under a man basket in just a zoom boom
  • 00:01:43
    and you know development this size you
  • 00:01:48
    can get some pretty hairy hair you loose
  • 00:01:51
    that you can't necessarily see now you
  • 00:01:58
    see some sub powder and some trunk line
  • 00:02:00
    hanging out there take care of that
  • 00:02:01
    usually we have an engineer behind this
  • 00:02:04
    too and he sets up a survey equipment
  • 00:02:06
    and points the laser anywhere there
  • 00:02:08
    there's something tight so
  • 00:02:12
    my partner here sees a red dot somewhere
  • 00:02:14
    he just knows to to give that rock some
  • 00:02:17
    some extra scraping until it's gone now
  • 00:02:22
    you see that right side is pretty here
  • 00:02:25
    pretty shitty lots of loose coming down
  • 00:02:30
    I don't give the face a scrape and pull
  • 00:02:40
    out we got the wash pipe hooked up paint
  • 00:02:54
    up all the bootlegs so we like to
  • 00:02:58
    visually check every barrel mark and
  • 00:03:02
    every bootleg and paint it up so when
  • 00:03:05
    the shock readers come in and shock read
  • 00:03:09
    everything they they don't shock read
  • 00:03:11
    over any potential any powder you know
  • 00:03:14
    boosters or anything that's going to be
  • 00:03:16
    left there because after shock reading
  • 00:03:18
    we're going to be rolling in and
  • 00:03:20
    punching drill steel through all of it
  • 00:03:22
    and it'd be a terrible shame to drill
  • 00:03:24
    into some powder and make a big mess and
  • 00:03:30
    you know he gives the face an extra
  • 00:03:32
    visual check see all the lights come
  • 00:03:37
    into saw the surveyors and engineers
  • 00:03:40
    come in getting ready to do their
  • 00:03:42
    mapping so after every blast we clean
  • 00:03:46
    out all the rock and prep it so it's
  • 00:03:49
    safe they come in and shoot it with a
  • 00:03:52
    bunch of lasers and computers and take
  • 00:03:54
    the exact almost like a 3d scan of up
  • 00:03:57
    the tunnel verify that we're online and
  • 00:04:03
    graded now here they go setting up this
  • 00:04:05
    computer nice flash lights to see the
  • 00:04:15
    scan there to expect 3d image at the
  • 00:04:18
    tunnel and we got the scoop ready for
  • 00:04:21
    quick cleanup before the chakras roll in
  • 00:04:25
    as you see we're just form welling up
  • 00:04:28
    here protect the equipment from all the
  • 00:04:31
    cement
  • 00:04:35
    [Music]
  • 00:04:38
    have definitely I think with shock reads
  • 00:04:40
    uh the care in your equipment is really
  • 00:04:42
    important you know when you got a
  • 00:04:44
    mistake and your pump and cement
  • 00:04:49
    you can't pump cement oh my god is it
  • 00:04:53
    ever a mess chasing your plug off and
  • 00:04:59
    it's just better to do I mean of course
  • 00:05:03
    it's better to do all the job right the
  • 00:05:06
    first time but you don't want to screw
  • 00:05:09
    up a shocking
  • 00:05:16
    so
  • 00:05:19
    right off the hop here where highs are
  • 00:05:21
    scaling we've got a very high pressure
  • 00:05:25
    water ball pressure washer on the end of
  • 00:05:29
    this boom here and it oscillates around
  • 00:05:32
    and you know gets with all the rock
  • 00:05:35
    surface wet sand and blows away all a
  • 00:05:38
    duster debris or any small pieces of
  • 00:05:41
    loose that were missed during the
  • 00:05:45
    scaling in the hand scaling process
  • 00:05:58
    go around the whole tunnel and then do
  • 00:06:01
    the base afterwards
  • 00:06:03
    and then usually when the shock readers
  • 00:06:08
    doing this behind the scenes the trans
  • 00:06:14
    mixers are setting up and and filling
  • 00:06:18
    the hopper you know getting the rest of
  • 00:06:22
    the heading tidied up so then when a
  • 00:06:25
    hydro skimming is done the the trans
  • 00:06:29
    mixer is already in place the hoppers
  • 00:06:32
    filled up and they're pretty much ready
  • 00:06:35
    to help you set up the boom hangout
  • 00:06:37
    there he comes already he's probably got
  • 00:06:41
    the nozzle to cap off the Smith put the
  • 00:06:47
    there you go
  • 00:06:49
    no more audio on my compressor get the
  • 00:06:53
    accelerant flowing prime the line with
  • 00:06:56
    some water
  • 00:06:59
    paper mask I was a part-time shock
  • 00:07:04
    reader spared nozzle guy it's back and
  • 00:07:15
    forth all the way around try not to get
  • 00:07:22
    it on the face too much and you know
  • 00:07:26
    where it paints out the bootlegs I mean
  • 00:07:28
    if they painted them up there's no snow
  • 00:07:30
    powder at all or supervisor bring me a
  • 00:07:34
    proper mask so usually we get a
  • 00:07:40
    prescription
  • 00:07:41
    you know when the engineer's come in the
  • 00:07:44
    last scene and do their mapping they
  • 00:07:46
    look at the rock test it all out with
  • 00:07:49
    their whatever they do and they
  • 00:07:52
    prescribed the shock Reed measurements
  • 00:07:55
    and the bolt lengths and patterns where
  • 00:07:58
    they want the ground support a lot of
  • 00:08:00
    times it would be you know 50 mil
  • 00:08:02
    shotcrete on the on the roof and or the
  • 00:08:05
    back and the walls sometimes it'd have a
  • 00:08:07
    hundred or you know depending on what
  • 00:08:09
    kind of class ground it is but you know
  • 00:08:14
    as an operator you're pretty much just
  • 00:08:15
    more on the roof and
  • 00:08:17
    supported like a tunnel kind of thing
  • 00:08:21
    fill in the holes try and make it look
  • 00:08:25
    like a tunnel you get rid of any rock
  • 00:08:31
    contours and try and fill it in so it's
  • 00:08:35
    all nice and
  • 00:08:45
    overlap it and you got to spread it
  • 00:08:51
    around evenly in not just a timely
  • 00:08:56
    fashion but like a timely organized
  • 00:08:59
    fashion because if you spray too much in
  • 00:09:01
    one spot to consistently get fallout
  • 00:09:06
    like it'll just fall off because you got
  • 00:09:07
    too much weight so you gotta evenly
  • 00:09:13
    distribute you know do you always want
  • 00:09:20
    to be you know like a 90-degree angle
  • 00:09:22
    from the rock that you're spraying on
  • 00:09:26
    and that doesn't mean you're always
  • 00:09:28
    straight up and down like the rock
  • 00:09:30
    contours are always different shapes so
  • 00:09:32
    you're kind of it just means 90 degrees
  • 00:09:36
    can be really any angle when you're
  • 00:09:39
    thinking about it from the booms point
  • 00:09:40
    of view it's almost like a 3d painting
  • 00:09:43
    of the tunnel filling in all the gaps
  • 00:09:47
    and provide the proper ground support
  • 00:09:51
    with shotcrete so you know it takes them
  • 00:09:57
    definitely takes some practice and
  • 00:09:59
    getting used to the controls you know
  • 00:10:02
    you can see here I'm standing sideways
  • 00:10:05
    to wrap my head around that these
  • 00:10:08
    joysticks and the way they've all moved
  • 00:10:12
    it's actually almost completely opposite
  • 00:10:15
    from the Copco Jumbos that we were
  • 00:10:18
    running here looks like we're done shock
  • 00:10:24
    reading now so it's a time for clean-out
  • 00:10:27
    and being this very shock reader
  • 00:10:33
    I was very happy this day a broken
  • 00:10:38
    pressure washer tip and I remember this
  • 00:10:42
    day specifically it was a Saturday like
  • 00:10:46
    Christmas holidays and everybody else
  • 00:10:50
    was up for pizza and you know once you
  • 00:10:54
    stop you start shock reading you can't
  • 00:10:57
    really stop until you're done because
  • 00:11:00
    you got to clean out and shocker is just
  • 00:11:05
    one of those things where because once
  • 00:11:08
    you start here you're in it until it's
  • 00:11:10
    done
  • 00:11:11
    cement don't wait for nobody unless you
  • 00:11:13
    ditch it somewhere
  • 00:11:16
    [Music]
  • 00:11:19
    so pressure wash the whole dome you know
  • 00:11:22
    if you do a good for my job it's easy
  • 00:11:24
    and if you don't make big mess you know
  • 00:11:27
    a bunch of spills or plug ups or rebound
  • 00:11:31
    everywhere you know you get the shock
  • 00:11:34
    review where it's supposed to go clean
  • 00:11:35
    up is usually pretty easy
  • 00:11:41
    [Music]
  • 00:11:45
    this is a very cold cold Christmas
  • 00:11:48
    holidays and well cold from British
  • 00:11:50
    Columbia anyways
  • 00:11:53
    get wet
  • 00:11:56
    [Music]
  • 00:12:00
    it's usually if shocked readers upfront
  • 00:12:02
    cleaning office boom you see I got the
  • 00:12:04
    caps on there
  • 00:12:08
    banging off the Sharpie pressure washer
  • 00:12:11
    so crappy tip broken no way to get a new
  • 00:12:16
    one now speed it up here go go faster
  • 00:12:25
    take that nozzle apart
  • 00:12:28
    scruple of shotcrete off
  • 00:12:31
    [Music]
  • 00:12:34
    another once-over
  • 00:12:40
    Craster
  • 00:12:46
    [Music]
  • 00:12:51
    I was cursing in my head the whole time
  • 00:12:53
    is fresh washer
  • 00:12:57
    and clean out the nozzle do this go
  • 00:12:59
    there
  • 00:13:01
    you know if you don't do a good job
  • 00:13:02
    cleaning out of this nozzle and all the
  • 00:13:04
    stuff you're just going to have plug us
  • 00:13:05
    next time then take off the cap no seeds
  • 00:13:10
    classes that rubber away nice
  • 00:13:19
    [Music]
  • 00:13:23
    took took the head apart they're clean
  • 00:13:25
    all the inside being inside the nozzle
  • 00:13:42
    game-planning wash out the back end
  • 00:13:45
    there
  • 00:13:48
    wrap up this friend knock over you the
  • 00:13:51
    nozzle has a little insert gonna wash
  • 00:13:56
    that out
  • 00:13:57
    [Music]
  • 00:14:07
    those of you like the sound effects they
  • 00:14:09
    hear the compressor ripping in the
  • 00:14:11
    background put that nozzle back together
  • 00:14:17
    grease up the insert and the
  • 00:14:23
    the rubber
  • 00:14:26
    [Music]
  • 00:14:31
    try and park
  • 00:14:34
    [Music]
  • 00:15:03
    hey wrap that boom up go help the guy in
  • 00:15:07
    the back end there get his clean out
  • 00:15:10
    done we get a purge
  • 00:15:12
    may you see big blast of water it's a
  • 00:15:16
    little line up and purge there we go
  • 00:15:18
    another one pressure wash pressure wash
  • 00:15:20
    brush wash and we're out of here bolting
  • 00:15:25
    time bring that pump in with the Jumbo
  • 00:15:27
    shockers never do you know I was just
  • 00:15:30
    shocked reading now you can see all our
  • 00:15:34
    are painted up bootlegs there so I like
  • 00:15:38
    to put my boom up drive in to the
  • 00:15:40
    lateral bolts flip it up get my bit
  • 00:15:43
    ready
  • 00:15:43
    I see clean up the cable hang it up out
  • 00:15:47
    of the water set up the total station
  • 00:15:50
    put your prisms up and go navigate and
  • 00:15:58
    step tap the last bolt row navigate
  • 00:16:03
    measure metering point 1.75 meters out
  • 00:16:07
    and start pounded in the holes here this
  • 00:16:13
    is a two point four meter mechanical
  • 00:16:15
    bolts
  • 00:16:26
    Constable's their partner hop in the
  • 00:16:29
    basket i paint out the bottom bootlegs
  • 00:16:34
    you start slamming in bolts where you
  • 00:16:37
    going so you've got a air impact we got
  • 00:16:39
    a air attachment in the basket their
  • 00:16:44
    hammers about we paints the depths of
  • 00:16:46
    the shock REIT so you can kind of get an
  • 00:16:50
    idea that's in centimeters so you can
  • 00:16:52
    see on the right a lot of the bolts are
  • 00:16:54
    5 centimeters and the top there's 10
  • 00:17:06
    centimeters that road for another row
  • 00:17:08
    two rows of bolts and navigate again it
  • 00:17:14
    is a four ring day two so this is
  • 00:17:17
    probably forty four two point four meter
  • 00:17:21
    bolts so as I said earlier those gos and
  • 00:17:27
    surveyors they prescribed all the ground
  • 00:17:29
    support so what they feel fit you know
  • 00:17:32
    sometimes we had three meter bolts we
  • 00:17:34
    had four meter bolts and times we even
  • 00:17:37
    had six meter bolts but later on in the
  • 00:17:40
    project we figured that if we're just
  • 00:17:42
    consistently doing two point four meter
  • 00:17:44
    bolts we don't need to have the five
  • 00:17:47
    meter steel on there and have the split
  • 00:17:49
    feeds fully extended so we just went to
  • 00:17:52
    short drill booms for bolting and and
  • 00:17:54
    even for probing just didn't use the
  • 00:17:58
    split feed anymore and it was it was
  • 00:17:59
    much more efficient and much easier to
  • 00:18:02
    move the booms around so usually when my
  • 00:18:10
    partners on the last row bolts I like to
  • 00:18:12
    wash the face with the boom so just turn
  • 00:18:14
    the rotation on take the bits off and
  • 00:18:16
    spray down the face so a lot of the
  • 00:18:19
    loose will fall off before he gets there
  • 00:18:21
    and he's safely out of the way it looks
  • 00:18:23
    like I forgot a bolt here too they sneak
  • 00:18:27
    in and drill a hole underneath them and
  • 00:18:30
    all the shock readers is already
  • 00:18:32
    hardened up and we're going in here it's
  • 00:18:33
    just additional mechanical bolts that
  • 00:18:36
    we're installing the shock read is
  • 00:18:38
    supposed to be good enough to work under
  • 00:18:41
    so I'm before we pull the Jumbo I like
  • 00:18:44
    to bang the bits and the steel off so
  • 00:18:45
    the if the mechanics need to work on it
  • 00:18:47
    in the shop and then my partner is going
  • 00:18:50
    to go up and paint up all the bootlegs
  • 00:18:51
    and get ready to drill around so I'm not
  • 00:18:55
    sure if my partner here is man or
  • 00:18:56
    machine never seems to stop never seems
  • 00:19:00
    to get tired never gives up always happy
  • 00:19:04
    to do anything with a smile on his face
  • 00:19:07
    and you know it's super important when
  • 00:19:12
    you're trying to get this work done and
  • 00:19:15
    you know if something goes wrong it's
  • 00:19:18
    there's usually a lot of labor involved
  • 00:19:22
    in mopping it up
  • 00:19:26
    like you know your blowpipe in your
  • 00:19:28
    clean up oil spills grumpo and rolling
  • 00:19:32
    up cable on roll on cable it's excessive
  • 00:19:35
    scaling and slinging speed rods and get
  • 00:19:39
    soaking wet and muddy like every single
  • 00:19:43
    day was just like underground life it's
  • 00:19:46
    awesome every day is like beach day
  • 00:19:50
    playing in the sandbox get the gear out
  • 00:19:54
    from a different angle here I like to
  • 00:19:58
    park the always have my next piece of
  • 00:19:59
    equipment right behind ready to go ready
  • 00:20:03
    to roll in I'd also like to point out
  • 00:20:06
    how nice and straight that vent tube is
  • 00:20:10
    gorgeous so we can just hop in the next
  • 00:20:16
    piece of equipment and you've got the
  • 00:20:17
    least amount idle time for the face so
  • 00:20:20
    plug it into the box right now I like to
  • 00:20:22
    move my boom ahead kind of cage wearing
  • 00:20:24
    in a how far away are going to be
  • 00:20:26
    drilling navigate again prisms up a
  • 00:20:30
    little station up then - don't look so
  • 00:20:34
    nice there all the fans off I must be
  • 00:20:37
    doing some work okay we start with the
  • 00:20:41
    lifters I always like to start with the
  • 00:20:44
    the bottom and we put tubes in the
  • 00:20:47
    bottom holes called the lifters and
  • 00:20:50
    paint a line so as the round progresses
  • 00:20:54
    and the drilling progresses sometimes
  • 00:20:58
    the face can really unravel and power
  • 00:21:01
    scaling is needed then we're going to
  • 00:21:03
    come in with a high mech later and hand
  • 00:21:05
    scale and you can make you know quite a
  • 00:21:08
    mess you can bring down a lot of rocks
  • 00:21:09
    and completely bury sometimes you know
  • 00:21:14
    your bottom couple of rows and if you're
  • 00:21:18
    going to hand scale at the - boom
  • 00:21:20
    hi mech basket and make a big mess you
  • 00:21:24
    can't keep bringing equipment in and out
  • 00:21:26
    of the face sometimes it's a long
  • 00:21:29
    distance until you can change what
  • 00:21:33
    equipment is going to be able to come to
  • 00:21:35
    the face I like to do scan - as soon as
  • 00:21:39
    possible
  • 00:21:40
    and I can see all my my tights from the
  • 00:21:43
    previous round and it gives me some time
  • 00:21:47
    added to game plan on where I'm going to
  • 00:21:50
    have tights drilling and as you can see
  • 00:21:53
    they're up in the computer screens I've
  • 00:21:54
    got lines and lookouts for every hole I
  • 00:21:57
    don't really have a choice of where I'm
  • 00:21:58
    drilling so sometimes if the previous
  • 00:22:02
    round is tight drilling the perimeter
  • 00:22:05
    holes is more difficult just because
  • 00:22:07
    your drifter and your boom is going to
  • 00:22:09
    be rubbing up against the wall or the
  • 00:22:11
    shock reader bolt so you see my partner
  • 00:22:15
    putting in the lifter tubes there this
  • 00:22:20
    is a 6 meter steel six point two meters
  • 00:22:26
    so I usually like to get all of the
  • 00:22:31
    holes that I need to do upside down so
  • 00:22:34
    as you can see my my drills are on the
  • 00:22:37
    bottom of my booms there I like to get
  • 00:22:39
    all the holes done on the bottom first
  • 00:22:43
    and then I can slowly rotate my booms so
  • 00:22:46
    they're upright and that reduces the
  • 00:22:50
    amount of boom movement and changes that
  • 00:22:56
    you have to do so also with these
  • 00:22:59
    Jumbo's - they have I think they're
  • 00:23:02
    called paramedics so you can set certain
  • 00:23:06
    angles of your boom usually you'll have
  • 00:23:08
    like a second function trigger on the
  • 00:23:10
    joystick and you can set different
  • 00:23:12
    angles and then here's your first
  • 00:23:15
    functions of the boom like rotate your
  • 00:23:19
    your elbow and in out up down left right
  • 00:23:24
    it'll keep the Jumbo computer will
  • 00:23:27
    automatically keep the same angles that
  • 00:23:31
    you're drilling so you can rotate left
  • 00:23:33
    or right and move up and down and that's
  • 00:23:36
    how you get a nice straight perimeter
  • 00:23:38
    nice straight box nice straight lifters
  • 00:23:41
    is you can just set your angle set your
  • 00:23:43
    boom and it the jumble do its best to to
  • 00:23:48
    keep it that way and then you can just
  • 00:23:50
    move across the face and drill all the
  • 00:23:52
    same holes with the same
  • 00:23:53
    look oh and it drastically increases
  • 00:23:57
    drill efficiency not having to move your
  • 00:24:00
    booms around not having to constantly
  • 00:24:03
    change your angles and I think it also
  • 00:24:06
    increases accuracy to like a lot of the
  • 00:24:09
    times there's optical illusions
  • 00:24:11
    underground you can't
  • 00:24:12
    is it really looking that far up or down
  • 00:24:15
    and especially if you're on a corner
  • 00:24:17
    ramp it's sometimes really hard to tell
  • 00:24:21
    and this is just isn't for computers
  • 00:24:23
    it's the same with just the hydraulic
  • 00:24:26
    electric Jumbo's with no computers they
  • 00:24:28
    still even the old school ones just
  • 00:24:31
    hydraulic functions that that keep the
  • 00:24:34
    angles I like to keep my hoses dangling
  • 00:24:39
    from the booms so straight down not
  • 00:24:43
    rubbing or sliding against anything that
  • 00:24:46
    reduce a lot of blown hoses the split
  • 00:24:50
    feeds you got a lot of hoses that have
  • 00:24:54
    to move constantly and that's why I find
  • 00:24:57
    that they break down a little bit more
  • 00:25:00
    speaking of breakdowns I think I've
  • 00:25:03
    mentioned a couple of times already in
  • 00:25:04
    this video about doing things right and
  • 00:25:07
    how time-consuming and costly it is to
  • 00:25:10
    do things wrong you know preventive
  • 00:25:13
    maintenance on all of the equipment is
  • 00:25:15
    super important the consumables on the
  • 00:25:19
    Jumbo x striker bars and bits steel
  • 00:25:22
    those I think are the first line of
  • 00:25:26
    equipment maintenance you got to have
  • 00:25:29
    good drill steel striker bars bits
  • 00:25:35
    otherwise you just work in the machine
  • 00:25:37
    harder and worn out threads you lose an
  • 00:25:40
    amazing amount of percussion especially
  • 00:25:44
    in the electric I draw of drifters is
  • 00:25:47
    there's so much percussion in limits and
  • 00:25:49
    you're losing so much with just the
  • 00:25:52
    burned-out threads and to break down is
  • 00:25:59
    especially if you got your boom up in
  • 00:26:01
    the air stuck in the back and you got to
  • 00:26:04
    fish the steel out you got no basket
  • 00:26:07
    it's difficult to deal with sometimes
  • 00:26:10
    we're going to move into the cut here
  • 00:26:12
    quick get a reamer on now let's we've
  • 00:26:16
    got a reamer on the right boom now heads
  • 00:26:19
    the remanence hole roll our garbage
  • 00:26:22
    explosives and started drilling the cop
  • 00:26:26
    with the left boom and we'll go right
  • 00:26:27
    into riemann with the right boom that's
  • 00:26:30
    kind of my strategy for pulling right in
  • 00:26:33
    front of the cut is one of them can
  • 00:26:36
    break down and if they're both good to
  • 00:26:38
    go one is drilling the blast holes and I
  • 00:26:43
    can get a reamer on right away and you
  • 00:26:48
    know you always going to add those to
  • 00:26:50
    this drill steel turn it and soon you
  • 00:26:52
    get REME in the better you can hear
  • 00:26:55
    they're aiming there the hollow the
  • 00:26:58
    hollowness of the big hole
  • 00:27:15
    residents out back there
  • 00:27:38
    [Music]
  • 00:27:49
    having here out of the temple surprising
  • 00:27:54
    no no gearing of the loading but go
  • 00:27:58
    right to scaling here
  • 00:28:00
    so after drawn for four to six hours you
  • 00:28:05
    can imagine it makes them loose so go
  • 00:28:09
    over the face of the bar many people
  • 00:28:20
    agree it would probably be faster to
  • 00:28:21
    just load them from the top down you
  • 00:28:26
    know we got a cap and powder map in the
  • 00:28:29
    baskets so you know top down and be
  • 00:28:35
    pretty fast but we scale it just be safe
  • 00:28:39
    scale a little thing all nice and then a
  • 00:28:46
    little ball the stick powder put stick
  • 00:28:49
    powder and all the perimeter holes we
  • 00:28:51
    usually use about four boxes of stick
  • 00:28:53
    powder per basket and then one box of
  • 00:28:58
    stick powder per side for each of the
  • 00:29:01
    the bottom perimeter holes we put six
  • 00:29:05
    powder in every perimeter hole we just
  • 00:29:07
    staggered one full hole and then you
  • 00:29:11
    know half a dozen in the next hole and
  • 00:29:13
    then the full avidin sticks all the way
  • 00:29:15
    around and made nice barrel marks all
  • 00:29:18
    the way around and with that six reamer
  • 00:29:20
    cut we almost never saw bootlegs after
  • 00:29:24
    we started loading like this so it gets
  • 00:29:28
    big six meter poles there lots of powder
  • 00:29:36
    partner had a hammer and in the powder
  • 00:29:41
    tamping it all nice and good nice and
  • 00:29:45
    good
  • 00:30:03
    stick powder all the way around again we
  • 00:30:10
    didn't really have a choice what we were
  • 00:30:13
    loading we had they gave us maps
  • 00:30:14
    everyday and they were coming in with
  • 00:30:17
    cameras and taking a pictures of before
  • 00:30:21
    and after the blast after we had loaded
  • 00:30:24
    it you know they're measuring the amount
  • 00:30:27
    of emulsion and keep tracking of every
  • 00:30:29
    piece of stick powder so say you know
  • 00:30:33
    screws up it's on them and we used to
  • 00:30:38
    scale real good so many holes that we
  • 00:30:41
    still like to do the bottom separate
  • 00:30:45
    well not separate but us a separate
  • 00:30:47
    person would take care of the entire
  • 00:30:49
    bottom pull it all the lifters needles
  • 00:30:52
    and a couple holes up and then once
  • 00:30:58
    everybody was done in the basket come
  • 00:31:00
    the hose that ran off the basket
  • 00:31:08
    you just come in and everybody tag-teams
  • 00:31:10
    we got two guys on the remote
  • 00:31:18
    do you guys in there phone to guys knows
  • 00:31:43
    you hear that a lot
  • 00:31:59
    I did find lovely emulsion at all
  • 00:32:03
    not spraying over there pump it into
  • 00:32:05
    water it's just like he's so easy can
  • 00:32:10
    feel it pushing the hose out so all this
  • 00:32:16
    stuff like was so easy
  • 00:32:21
    a skier
  • 00:32:24
    makes a big difference
  • 00:32:28
    [Music]
  • 00:32:32
    faster-faster-faster
  • 00:32:45
    being a little bit AMX I always like
  • 00:32:47
    blowed top-down - because you're pushing
  • 00:32:51
    all the water out or training here the
  • 00:32:53
    hole below it but I'm also marry me
  • 00:33:00
    so you get the hold cut there for
  • 00:33:03
    Reimers later on after this salt film we
  • 00:33:10
    switch to six reamer cut and we never
  • 00:33:14
    had even a button mark off of these
  • 00:33:16
    never again
  • 00:33:19
    [Music]
  • 00:33:21
    barely ever read last I always you
  • 00:33:26
    barely ever because I'm sure there was
  • 00:33:28
    one but just said not even button Marx
  • 00:33:33
    is almost over break every round and you
  • 00:33:36
    know if there was major screw-ups during
  • 00:33:40
    the blast a lot of the times it was a
  • 00:33:42
    human error like you know emulsion is
  • 00:33:44
    finicky the equipment not blame humans
  • 00:33:47
    but human controlled variables you know
  • 00:33:52
    pre maintenance checks and stuff like
  • 00:33:54
    that that slipped by us and it screws up
  • 00:33:57
    and we have to forfeit something and
  • 00:33:59
    it's not perfect and that's how it goes
  • 00:34:02
    and when I say emulsion is more finicky
  • 00:34:05
    than am exits that's not really so it's
  • 00:34:07
    just there's more to setting it up you
  • 00:34:10
    know you got your water pressures and
  • 00:34:12
    slick in your line and the right water
  • 00:34:15
    mixture not too much water and so it's
  • 00:34:20
    there's more steps to it so it's easier
  • 00:34:22
    to screw up and when everybody is kind
  • 00:34:26
    of doing a little bit everything like
  • 00:34:28
    you're always carrying something or
  • 00:34:31
    always working as you go so there's
  • 00:34:34
    never a wasted step and sometimes
  • 00:34:36
    multiple people doing multiple things on
  • 00:34:40
    multiple jobs sometimes some things get
  • 00:34:43
    missed and you know you get that
  • 00:34:45
    complacency and you just forget to
  • 00:34:48
    double-check and something gets missed
  • 00:34:50
    and and then that's usually when you
  • 00:34:53
    have a repast so it looks like we're
  • 00:34:57
    getting pretty close to having all those
  • 00:35:00
    holes filled with emulsion start clean
  • 00:35:04
    out pretty soon clean out you got a pump
  • 00:35:07
    the last little bit you know make sure
  • 00:35:09
    that there's no more explosives in the
  • 00:35:11
    line and then you slick it with water so
  • 00:35:16
    the next time you pump you prime it with
  • 00:35:18
    water and keeps the emulsion flowing
  • 00:35:22
    start tying in here
  • 00:35:33
    like to go up to the top sir from the
  • 00:35:35
    center it doesn't matter where you start
  • 00:35:41
    but it is important that your be line
  • 00:35:45
    this is a nice circle not a square or
  • 00:35:50
    rectangle or any sharp angles because
  • 00:35:53
    they the B line
  • 00:35:56
    I'm sure if I'm wrong someone will
  • 00:35:58
    correct me
  • 00:35:59
    it's like 22,000 feet or second and I
  • 00:36:03
    use blow right off corner so you want to
  • 00:36:07
    have a nice nice circle shape and
  • 00:36:09
    usually two two leads or the more the
  • 00:36:12
    merrier
  • 00:36:14
    and nice clean tie ons and of course
  • 00:36:19
    every part of the cycle is important and
  • 00:36:22
    it's important to do every part of the
  • 00:36:24
    cycle good but when it comes to blasting
  • 00:36:27
    you've done so much work to get that far
  • 00:36:30
    and to get that blast to screw it up by
  • 00:36:35
    doing something sloppy or messy or not
  • 00:36:38
    time's up again it's all of that work
  • 00:36:43
    down the drain
  • 00:36:45
    or just putting more work on your plate
  • 00:36:47
    so just like some men just like drilling
  • 00:36:51
    you're going to do it right but just
  • 00:36:52
    just do it right and it'll pay off I'll
  • 00:36:56
    speed this up faster go faster
  • 00:37:10
    shut up and I am
  • 00:37:33
    that's better fast mode
  • 00:37:35
    a worker way down the sides someone will
  • 00:37:40
    probably come in from the bottom here
  • 00:37:41
    start tying and the lifters yeah there
  • 00:37:43
    you go
  • 00:37:45
    just teamwork all the way through whoo
  • 00:37:52
    nice cut nice Italian job - I usually
  • 00:37:58
    like to wrap them up in little bundles
  • 00:38:00
    but we don't really have much trunk line
  • 00:38:01
    left oh I forgot we had some tight
  • 00:38:05
    supplies to go up oh that was stick
  • 00:38:12
    powder drop some beeline drop the bolt
  • 00:38:16
    so want to keep the mechanical bolts tie
  • 00:38:23
    that in
  • 00:38:33
    faster
  • 00:38:38
    okay Tran this thing out there you go I
  • 00:38:43
    think it's important to note on the tram
  • 00:38:46

  • 00:38:48
    perfect and you'll notice on all our
  • 00:38:52
    chiming videos that the vent tube is
  • 00:38:54
    perfect it's really important to have
  • 00:38:58

  • 00:39:00
    have walk it back and forth too far
