I did the labor of loading holes as a teenager back in the day during the summer break, unloading ammonium nitrate off trucks and setting them up next to drilled holes, setting the blast up with nitro glycerin and blacking caps then loading ...

It was a great experience, hard work really put the light in my eyes and appreciate my dad's living , plus I couldn't quit because the boss was also my dad.
Very nice. Thank you for giving the regular people a peek into the world of blasting. The video was very well done. Labor intensive work it is! I'm an old doodle bugger. Shooting holes looking for oil. I loved seeing charges go off.
In 1969/70 I worked at the Koolanooka open-cast mine in Western Australia. By mining standards of the time, it wasn't a large operation, but the midday and 5 pm blasts were always memorable. The mine workshop was a bit over a kilometre away from the pit and the blasts usually shook the dust out of the rafters. The biggest bang while I was there was 94 holes and really rattled our fillings. Later, I saw the car belonging to one of the engineers. It had a huge dent in front of the windscreen, which was still intact, and I could reach under the windscreen and put my hand on the dashboard. He told me that he was in the car at the pit, watching the bang from a safe distance, and saw a rock flying towards him out of the dust cloud. He thought it might hit him, so he rapidly reversed thirty metres and the bloody rock *did* hit him.
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.
When I was working in a quarry, there finally came the day that we had to blast straight down into the floor for the next level. Rocks went straight up into the air!
When I was a kid we use to buy a stick of dynamite for 25 cents caps were 10 cents and the fuse was 3 cents a foot , me and my buddies use to play war with it , that was before all the crazy people came along .
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.
In Italy we cannot use bulk ANFO, it must be packaged as cartridge and is expensive as other explo. For outdoor excavation we use varnish slurry in cartridge , dynamite, detacord and electric caps. For underground excavations, road tunnels mainly, slurry and micro-delayed detonators
I remember about 12-15 years ago, I watched a video very similar to this where they basically took a ridge like this, but about the length and width of a football field. The video showed the machines come in, bore the blast hole, the engineers come and set up the explosives (my son didn't realize that not all explosives are shaped like dynamite sticks or C-4 blocks) and when all was set up, an old school plunger generator was used to set off the explosion-the whole area rose up about 6' and then dropped about 4' from its start and a huge cloud of dust took several minutes to blow away.... VERY satisfying to watch...
Thanks for showing this! I was a aggregate inspector for Illinois Dept. of Transportation. I spent a number of years at limestone quarries in my area. I loved being in the quarries. Retired now but, this really takes me back. I miss it!
Reminds me of when being interviewed by a phycologist in Armageddon, Rock Hound explains why he drills: "...Why do I do this? Because the money's good, the scenery changes and they let me use explosives, ok?"
When I started public school, was in a one room school house. A corner of the building had off colour brick work. I later learned that a few years before, the older kids had stole some dynamite from one of their father's (a farmer) shed, and set it beside the school thinking that it would blow the building. They didn't know enough about blasting, so it only damaged the wall. But did they get in shit. LOL. Later, while still before high school, I watched while a neighbour blew a stump, over 5 ft wide (this was in the 50's when there were still trees that size from old growth). Then the government brought in laws about storing and who could own blasting material.
An anfo truck blew up here in Western Australia a few months back . 1 of the wheels on the trailer caught fire . The driver stopped the load in the middle of nowhere and disconnected the truck and drove away. 1 big boom later and the road section and trailer were gone ...
What we also liked to use for our explosions was the gunpowder from discarded machine gun ammunition. We collected tons of MG belts at the US Army training area and sawed open the cartridges and collected the powder.
I work at a rock crusher and we blasted 300 holes at once with anfo and HPD3’s. That’s back in the 80’s. It’s a lot of work especially if holes were wet. 👍
working in 1965 on the Adirondack Northway spent that summer in a big rock cut, blast at the end of every day, dynamite back then, three foot long , we would walk the 4 and a half yard shovel a safe distance away and turn it around , we would take shelter in the bucket for the blast
*_Most people only see the 'button' being pushed and thousands of tons of rock blown up_* Many variables determine final effects of blasting; diameter of hole, depth of hole, angle of hole, spacing of holes, types of booster charge, type of blasting cap, delays of blasting caps, type of main explosive charge, and type of tamping. When everything goes right, rock is fractured enough to minimize primary crushing.
In the military we did the same thing to mountain/foot hills dirt roads. We used C4 placed down into the holes drilled. When you have rocks the size of cars landing around you, you could know then you were too close.
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.👍
@@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.
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. ua-cam.com/video/gNIIZ0cGx4k/v-deo.html
The most dangerous holes are those which are closest to the free face. Over-dig your faces and drill a hole thats too close to the edge and you'll be making big time flyrock and fatalities.
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.
@@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.
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".
I work in a open pit mine similar to that one. I don't know where that one is but I know if it's here in the states the people better hope msha doesn't watch this video. I saw two major violations. Poking the power with the cap one and two wiring them together soon as you finish putting the powder in the hole.
Would it help the blast yield if a tamper barrier at the top of the charges were then filled with a sealant then water or soil to keep any gases in the target mass instead of being vented out the bore upon detonation? Instead of that tall plume of outgassing, it could be kept within the blast target.
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.
@@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.
Andere füllen das ANFO einfach aus einem Betonmischfahrzeug ein. Das spart das Schleppen und Öffnen der Säcke. Others simply fill the ANFO from a concrete mixer truck. This saves lugging and opening the bags.
Yes, the good old days. When we were 13 to 15 years old, we had our bad reputation in all the villages around and didn't get any more chemicals sold, which was very annoying for us. but at the age of 15 the next challenge of life started: GIRLS!!!
I wonder if these guys set off the explosive alarms then they walk through an airport? It is interesting that they put the detonating charge on the bottom of the hole and not on the top. I would have though that the detonator charge would blow the ANFO out of the hole.
@@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.
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.
How many here think the regular AN without the FO could do what happened in Lebanon ? It seems like here, the explosion is rather small, and with lots of ANFO and proper equipment. Can AN explode with the same power as ANFO ?
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.
🇺🇸💥I had a great childhood, my grandpa and dad did blasting, excavation, and plumbing. Needless to say there were some great and exciting times. I loved the blasting times so much I joined the Army as became a 12B.....COMBAT ENGINEER baby!!! 🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🧨💥🧨💥🧨💥🧨🧨🧨💥💥💥 By the way shooting dynamite with a shotgun (lead shot) will cause it to go boom👍😊🇺🇸🇺🇸
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.
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.
I really like this video but I do believe a voice-over would help. I come from the mining industry and so I know what's happening but the mining industry is not that big so I can imagine a lot of people don't know the steps and what is happening.

The biggest bang while I was there was 94 holes and really rattled our fillings. Later, I saw the car belonging to one of the engineers.

@@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.
What stuff are they mining? Some kind of ore? Or limestone for making cement?
Amazing
Love casually shoving a blasting cap into a sausage bag of booster.
Liked and subscribed 👍 Cool video 👌🙂
Useful video bro I like it☺.but Need some explanation of connections tooo... 👍
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".
Same process as what they do for our quarry except they have bulk trucks for the anfo our stone is burned in a power plant high calcium limestone
I work in a open pit mine similar to that one. I don't know where that one is but I know if it's here in the states the people better hope msha doesn't watch this video. I saw two major violations. Poking the power with the cap one and two wiring them together soon as you finish putting the powder in the hole.
The writing on the bag was in English and Turkish. The truck license plate was also formatted for Turkey.
Thank you!
Would it help the blast yield if a tamper barrier at the top of the charges were then filled with a sealant then water or soil to keep any gases in the target mass instead of being vented out the bore upon detonation? Instead of that tall plume of outgassing, it could be kept within the blast target.
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.
Cool !!!
🙂😎👍
Dynamitt Harry!
Thank you
Very good Brasil 🇧🇷🇧🇷🧨
Oh cool I love how you have NO DUST SUPPRESSION. Wonder what you were breathing in?
Andere füllen das ANFO einfach aus einem Betonmischfahrzeug ein. Das spart das Schleppen und Öffnen der Säcke.
Others simply fill the ANFO from a concrete mixer truck. This saves lugging and opening the bags.
Emulsion phase is easier...what are they blasting?
Yes, the good old days. When we were 13 to 15 years old, we had our bad reputation in all the villages around and didn't get any more chemicals sold, which was very annoying for us. but at the age of 15 the next challenge of life started: GIRLS!!!
Thanks to Mythbusters for teaching me what ANFO is.
That must be the size blasts the gravel pit across the street from my house uses…
I wonder if these guys set off the explosive alarms then they walk through an airport?
It is interesting that they put the detonating charge on the bottom of the hole and not on the top. I would have though that the detonator charge would blow the ANFO out of the hole.
what are they mining
Why is your ANFO 1.5D and not 1.1D?? I notice it says "Booster sensitive" on the bag, but you are priming with packaged...
The quarry is in Turkey so maybe they do things differently over there.
blast to extract which material?
Anfo is crazy stuff
Ammonium nitrate
Can grow stuff
Or add a little fuel oil and boom
Thank you for sharing. 💥
that pink explosives looks tasty )
5:18 is that M.C. Hammer? damn can't touch this....
What is that white saussage they stick the blasting cap in ? is that a secondary primer to trigger the ANFO ? Are these sticks of dynamite ?
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.
I'm surprised they don't have a machine that sets the charges
I like
That is cool
That is one great big Triple-nickel 40
What's the story on the lights that travel down to blast area just it lights off? Thought that odd.
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.
Hooking up TLDs before loading with anfo 😬
How many here think the regular AN without the FO could do what happened in Lebanon ? It seems like here, the explosion is rather small, and with lots of ANFO and proper equipment. Can AN explode with the same power as ANFO ?
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.
🇺🇸💥I had a great childhood, my grandpa and dad did blasting, excavation, and plumbing. Needless to say there were some great and exciting times. I loved the blasting times so much I joined the Army as became a 12B.....COMBAT ENGINEER baby!!! 🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🧨💥🧨💥🧨💥🧨🧨🧨💥💥💥 By the way shooting dynamite with a shotgun (lead shot) will cause it to go boom👍😊🇺🇸🇺🇸
LOL! And let me guess how you know this...
@@jesseamaya4413 😁😉😉😉😉
Perfekt 👍👍👍👍💪💪💪💪
You could grow a ton of corn with all that ammonium nitrate.
The amount of Anfo they used was staggering. What was the plastic they put in the bottom of the hole below the Anfo?
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.
Salaam dari Indonesia. !
i would love to know the cost of a blast like this compared to the material take from the site after the blast. im a numbers nerd that way
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)

What is the depth of hole?
They are sure good at blowing things up over there.

So much energy in chemically bound nitrogen.
3:40
Its a girl! Yay!
What the hell?? You can actually see the electricity or at least something going down the wire?? What caused that light?
I really like this video but I do believe a voice-over would help. I come from the mining industry and so I know what's happening but the mining industry is not that big so I can imagine a lot of people don't know the steps and what is happening.
Esses caras tem muita "" coragem de manusear isso que explode o sol o calor pode detonar
The holes I loaded we had to use slime, holes had water in them.
