Bolting and Meshing an underground mine heading.
This is where the jumbo operator has finished scaling the heading to remove most of the loose rocks. He then manipulates sheets of mesh, 2.4m wide and up to 5m long, into position with the jumbo's boom(s). He then drills holes and 'bolts' (pins) the mesh onto the rock surface with a variety of 'rock bolts', measuring from 900mm long, to 3000mm long (generally about 47mm thick). My job is to train him how to do this, especially when using different and new bolts, that he might not be familiar with. This guy is an artist. No names, as we are not discussing which mine it is. I wrote him a nice report for his boss!

Scaling an underground mine heading.

Jumbo operator using the jumbo to scale down a heading in an underground mine. This is a method of removing loose rock, so it does not fall on someone later on. Very important! See my other video for an example of Bolting and Meshing, This is where I work, down the hole!
Driving in the snow in Tassie last week.

Driving to work at 4:30 AM last week. Sorry about the swearing, if you're a bit sensitive to that. Bit of a funny at the end, as one of my passengers has the nickname 'Frosty'. Followed the trucks tyre tracks, as the road was 4 inches thick with snow, then another inch under that of ice. I tried to overtake him once, using the uhf to communicate, but the ute tried to turn around, even tho in 4W...

1 year old Tayla, chasing our 2 y/o rag-doll cat, Mang, around the Lounge room. He was very patient and behaved very nicely, reluctantly tho.

Big CAT truck being transported to Prominent Hill mine. I think it was a 793 or bigger.

Met this truck on it's way to Prominent Hill Mine. Shot this near Port Augusta. Sorry about the focus, but you'll get the idea how fn big it is anyway.

Flood crossing near Axedale, Victoria

During April 2011, we had a bit of rain around the region, so a few creeks and rivers flooded. We went for a look, and decided to have a crack at crossing this one, near Fosterville and Axedale, in central Victoria. Bit of fun.
Overtaking a roadtrain in Outback SA

Overtaking a roadtrain on my way to Prominent Hill minesite. Watch how narrow the window of opportunity is, before the lines change back to 'no overtaking'.
looks like the Aussie way. 🤣
Trabalho com esse telamento, mas levantamos 4 telas de só uma unica vez
Thank you so much
dang take it easy on the gear wreck it Ralph...angles and read the rock
Broo that is not proper scaling it's very big risk for machine and individual around positioning angle of boom should be at least less than 65 rambert to scale from firm to weak ground
Is that a trainee operator?
What's the go with the off side going past the front jacks to put a bolt on while the operator is still drilling?

Poor jumbo
Mata equipos carajo
Basically the nipper goes under unsupported grounds?
Not true you put the mesh and bolts up where the nipper has to walk first. The boom can be turned back towards the cab so he is under supported ground. Unless you have an inexperienced jumbo operator that doesn't know what he is doing or doesn't care about his off sides safety.
Obviously no nipper switch 😉
Bro next time you want to scale always put your boom on a 60°angle and scale from good to bad you will never have unnecessary breakdowns imagine you are using a pinch bar to scale down can you do it in that way?
Mesh and bolts
Faarrkk man i reakon i could shave a minute off that quite uncomfortable, awesome video never the less
Paid by the hour gummon
Should put your rear jacks down mate. And scale from good to bad, too much fallen on the rail, suprised you didnt loose a hose or 2 of your rollover!!
Expert
You have intered the rock bolt and other whts entr red red plz tell me
Took 3 minutes to get your steel turning. Take a video once your good. Cheers
and this is why australia is the leader in underground development
Cause they say fuck it
Indigenous people deserve a cut from you dingos
Nothing really special about it really

Is that a miss hole right there in the middle? Torturing the steel. Beating the crap out of the drifter and shell. There's better ways and scaling off the muck pile isn't one. Rattlibg the back with the jumbo gets loose down we'd never have gotten down with a scaling bar. Hard rock like this, it gets the job done if there's no scaler in the fleet. I'd think flattening out the shell quite a bit would do the same with out getting so many rocks down on the drifter and feed.

Qué manera más peligrosa para acuñar
That's called power scaling, son.
this mesh and cable bolts are such a nuisance, jams up the crusher up on the processing plant!
Better than having the back fall on your head
Reece, when I worked underground, we used a scaling bar which has a tip much like a crowbar. Shove the point into a crack and pry the rock loose rock. I thought it was one of the hardest parts of the mining process.
Good jumbo Op still does a bit of clean up for his own safety.
Pablo Sepulveda have you got a better way to scale unsupported ground?
The right way is with s scaler or scaling bar... is too much money loosed to scale with a jumbo
Using a Jumbo to Scale the Heading... Nice... I'd like to see the Operating cost of that Critical Equipment and the mechanical availability... Production goes down!
Hahaha...true
Nah mate its way quicker than any other way. Machine availability is suprisingly high around 90%. Only a Sandvik can do it that quick those yellow pieces of crap wont do it!!
Most of the mines are recommending to scale with a Jumbo but it's costly
It’s standard practice at our mine. Part of the cycle. Mechanicals scale, bolt/mesh, gewi, bore.
The equipmet to do it is a SCALER, a jumbo is for drill production or development... at last use a retro with hammer but not a jumbo... think about the time of production valorized when jumbo is out of service or used to scale compared againts the real work to do in tons per hours loosed because loosing time
We want fire it to day have a go lol bit quicker than me old m2d
it took nearly two min to pin the mesh to the wall, talking about the right tool for the right job
