what year was this

I would not want my son near nitro glycerin.

😂 fucking australians, gawd I like you people!

This quarry was setting up for a shot and was ready and me and the drillers son were going out to stop traffic. We were a good 1/4 mile away from the shot but could still see the quarry. We were just talking about how glad we were we as far away from the shot when they tapped the trigger and UP she went. We aere OOH and Ahhing when a rock the size of a basketball fell 10 feet in front of us. You can't be too far away.

Brings back memories. Was in Mt Magnet - Black Cat (Parkinson pit) with Metana Minerals, early 90's. We shared the pit with Western Mineing Co. They worked the south half, we worked the north. Filled in on the shot crew for a few mths & did some big shots there. Blew half the floor in 1 shot. 3x3 mtre pattern. about 50 m wide x 150m long x 5m deep. 25 mil-sec spread runs a nice wave across the floor. I always hit the siren stationed about a mile away up on the southern rampart about 180 mtrs high, & always remember seeing rocks flying well above my height. We had some realy hard granite sections in the floor that caused a few problems at times. One shot shifted the entire shot sideways about 5 metres. About 30,000 ton of rock in one hit. Gave me a huge respect for the power of modern explosives. Hell of a mess for the geos. They had to come back down and try find and mark out the ore body again amongst the rubble. Shot was supposed to just shatter and lift rock, but it echoed off a granite dyke and punched it all sideways. Ooops. It was incredible to be 150-160 mtrs down in this huge open pit and come across an old hand cut shaft from the early days. Ole boys knew what they were about, following fine gold down that far with a pick & shovel.

@@colb9916 I was running a 980 or a 115 and got to clean up the floor after a shot. It was the same quarry I helped clear, grade and set up years ago; HARD granite. The shots were usually around 90K tons and if they ran hard it'd last 2 weeks and if they didn't shoot at lunch/dinner time they'd be out by quitting time. A lot of paving was going on and the plant was trying to stay ahead with p-gravel and made sand. I got to help load a shot with the powder monkey I'd known for years and that's when I found out about the tube and aluminum powder and pre-shaped charges and easy hookups and a percussion cap detonator. I'm from the old school electric caps and a detonator box, not a plunger but capacitor type. And the shooter set the wall charge off first to keep the rest in a hump. Pre-split they called t he wall and did it with det cord. And there were no BANG's unless there were boulders getting pot shot. Just a big WHUMP and the kissh as the shot settled back down on the floor. I miss the equipment but not the politicks. CHEERS!

@@lewiemcneely9143 Yeah a lot has changed even since i was there. We mostly used 15 ton truck loads of amfo slurry (porridge)delivered from geraldton, poured in the hole onto a G-primer charge or 6x1 inch powergell sticks and a delay det. Tied it all together with detcord, and Max fired it with a match ignited 5 min delay number 3 det. It was all pretty inert till tied in and ready to touch off. Kinda crazy that we got realy complacent with so much boom. Amfo make 1 hell of a crack.

Not many folks realize a good shot is a WHUMP instead of a BANG.

@@lewiemcneely9143 Or, in the case of cutting a channel in a narrow space (bottom of a canyon, for example), it sounds like a loud, muffled zipper...

@@johndelaney9399 RIGHT!

Wtf 🤣

Dude epic, I would have loved that

Over 40 years ago when I was a freshman in college, I had a required speech class that as one of its requirements you had to give a demonstration speech. In other words, teach the rest of the class something. Being a redneck from Texas and a bit of a smart ass, I taught my class how to make a small PVC pipe bomb. Thankfully my professor had a sense of humor. Today, they’d have had me arrested, I’d have been thrown out of college, and I’d spend the rest of my life on several lists. We didn’t mean any harm. It was just a way to fish the lazy way.

There was about two tons of Fekabit (potassium chlorate) in the equipment warehouse of the sports field for weed control. Then someone figured out that you can mix it and sugar 1:1 and create a bang. The game continued until the substance in one boy's pocket burned his pants and little more.

Kids playing with dynamite? I don't mean to be a stick in the mud, but I think you were the crazy people! 😂 I did some sketchy stuff with fireworks and toy cap guns as a kid but dynamite is next level.

Jackie S .......I was the drill and blast supervisor in a mine where we had 3 GD100's back in the early 80's. Nice machines.

I was an industrial electrician and was the first hired for the GD12-GD100 project. when GD moved into the new plant outside Dallas.

Good old MSHA but they were just trying to keep you alive.

Всё хорошо, понятно, что здесь добывают?

@@user-pi7tz3mp7p Не уверен, что добывается, может быть, продукты щебня.

do you recommend double wrapping cord around a connector or does this increase the chance of misfire?

grabir01.......sounds like amateur hour blasting to me. C4 isn't the best thing for blasting rock.

an effecient blast minimizes fly-rock and maximises breaking

What are you mining for and what do you think this place in this video is mining for?

@@tedtedness184 We used slurry trucks blasting for highway construction back in the 70's in Texas. You got to work on the blasting crew if your haul truck was down for repair. These guys tie-in their "donkey dicks" a little different before sending them down the hole than we were taught, but it works. And yes, we have limestone hills in Texas. In road construction here, you blast the hills and crush the limestone for road base. State comes out and approves or rejects it onsite. Saves on road trucking charges from the quarry.

Ours did too. 135-12" holes would take forever to do by-the-bag. (Open pit Copper Mine)

@@lakesnake2005 Interesting there are at least two professions that use donkey dicks: blasters and plumbers

Check out this pond blast video. You can see two slurry trucks leaving the scene prior to blasting. In this video they are blasting straight up so they end up with a hhuge pile of rock. Probably more impressive than the blast in this video. kzfaq.info/get/bejne/nbR5fL1hyK3cZJ8.html

And I operate a loader that loads over the road trucks after it's crushed and separated in different sizes. I love my job, just wish it paid better. I tell people who ask what I do , I respond I run Tonka toys which kids like my answer.👍

@@jeffharper7579 I will answer the kids saying that I play boys toys in a quarry😂

👍🚜

The writing on the bag was in English and Turkish. The truck license plate was also formatted for Turkey.

That is a small explosion travelling along the det cord. Det cord (detonation cord) is a tube filled with explosive that is sued instead of fragile wires.

That is a safety light to get everyone away before the blast. Last warning))

@@jimmymcjimmyvich9052 If you're standing next to one of those lights, going by, it's already too late for you.

@@pjford1118 that's not det cord that's shock tube.

@@pjford1118 interestingly, it's not detonation cord. It is shock tube. It has a fine layer of explosive on the inside (correct me if I'm wrong but from memory it's HMX and aluminum powder). Shock tube remains intact after its fired, you can actually hold it in your hand and fire it. The low intensity shock pops out the other end and fires the primary explosive in the detonator, which in turn fires the base charge of RDX or PETN in the detonator.

At are lit we pump that shit in than you fill hole with fines

Ours was a granite quarry and would process 90K+tons in 2 weeks. Put a shaped charge on the botton, ANFO up the hole so far, another shaped charge and filled the rest of the hole with p-gravel. Worked fine.

With that much depth, it really won't matter much.

@@christopherleubner6633 Old shovel operator helped load and said he was tired of the boulders. Poured the pink fertilizer to the top after the baloney sticks at the bottom with the cap and kicked a little dirt over it. You best find a good hiding place when the trigger was tapped but that did it for the boulders. And the more you can contain a shot the better it'll pulverise it.

Different colored wire with various colored stripes designate appropriate delays so the blast propagates correctly. And they just snap together like wire tap connector. We didn't have a snazzy little detonator like that, ours was big and heavy and you set it off in a little steel "doghouse".

The quarry is in Turkey so maybe they do things differently over there.

That's the explosive 🧨, tnt , nitro glycerin

@@jackalope4286 the main explosive is the Anfo (the Amonium Nitrate/Fuel Oil compound - See en.wikipedia.org/wiki/ANFO) ... I'm talking about the stuff they put the blasting cap in or those small elongated bags the guy @2:16 is droping on the ground and then again shown @3:08 and @4:08 where they are poked with the blasting caps.

That's what it is bubba - blasting cap goes into (nitro glycerin/ tnt) sausage package, it can also be a hard stick of tnt like a bar of soap, when it's detonated, it goes boom and ignites the ammonium nitrate and creates a bigger boom , then you get busted up material to mine/ process/ crush sell whatever.. big 💵

@@jackalope4286 All right, so that's what I am saying.. They are using some form of high velocity explosive (c4, semtex, tnt, whatever primed by a blasting cap) as a secondary primer to trigger the slow but dirt cheap main explosive (ANFO).

It’s an emulsion filled stick of explosives...powder. If the holes were making water the Miners would use larger sticks of powder to load because the ANFO would just wash away.

LOL! And let me guess how you know this...

@@jesseamaya4413 😁😉😉😉😉

The problem with the AN in lebanon is that it was old, and there was a large quantity of it. When it decays it becomes more flammable, and puts off ignitable gasses which will cause an explosion. The Ammonium nitrate in Beirut also had little to no containment, so the shockwave was devastating. The amount of AN was equivalent to the amount used in blasts at the mine where I work (aprox 300K Kilos), except in a mine blast the explosives are contained by rock, so the shockwave is confined.

That’s detcord. The yellow stuff they tied in to the plastic sausage looking things with blasting caps. See the channel ordinance lab for an explanation

@@davidelzinga9757 What we used was a tube that looked like weedeater line filled with aluminum powder. It was set off by a percussion cap like for a muzzle loader and you can see the fire in the tube glow as it goes through the shot if is is dark enough.

@@davidelzinga9757 it is not detcord. It is Nonel, non electric shock tubing with a microthin coating of HMX. You can hold it in your fingers as it goes off but it will give you a good smack. With detcord you would lose the fingers.

Don't know what compuond it is but it is a primary explosive to set off the secondary explosive anfo. Anfo will not explode unless provided with sufficient energy, the blasting cap at the end of the wire will set off the compound in the plastic bag and the compound will then set off the anfo.

An explosive booster charge. Looked like a gelatin explosive. Needed because the blasting cap will not detonate the ANFO directly.

Booster charge, generally it is made of a mix of RDX plus PETN 70/30 in a plastitizer. For this use, it would have aluminum powder added to make the blast hot as well as brissant.

Well, if it is being blasted, than it shall be economical effect after drilling, blasting, hauling, enriching and shipment. Even more, this might not be the needed material, that might be the rocks that has to be removed in order to just bring the surface to the needed rock. And it must be feaseble. I bet you can google the papers which tell you how to calculate everything, even the needed amount of explosives.

Didnt give you the answer lol)
