- NOTE: Although this video shows an up-close look at the blasting process, NEVER go near an active surface mine or blast site without Federal training and permission.
FYI, the white bags are Emulsified Ammonium Nitrate. The read cap is TNT and the silver rod that is connected to it by the yellow wire is the blasting cap, it's what ignites the shot. The white pebbles that are emptied into the blast holes by the powder trucks are the main explosive- "ANFO" or Ammonium Nitrate, which is a mixture of fertilizer and diesel fuel. Once the holes are filled with explosives, rock fines or "stemming" is pushed back in the holes and packed down to keep the explosives under pressure. After all the holes are loaded and rigged up, it's time for the fireworks! And remember kids, don't try this at home!

Josh, I did this when I was 16 years old at Eagle Mountain Iron Mine. I got 5 bucks an hour. I thought I was rich. The yellow cord is called blasting cord which is detonated with a high voltage electrical charge. It explodes at the rate of three miles a second. The red charges are called titan boosters and are used to set off the actual,explosive charges which are placed in the drill holes. The holes are about twelve inches in diameter and vary in depth. The explosive is a large cartridge, about twenty five pounds of nitrogen prills , little BBs, thoroughly soaked in diesel fuel. Some of the holes call for ten or twelve cartridges each. Without the Diesel fuel the prills are just garden fertilizer but the chemical mixture makes for a ultra high energy explosive charge and it is relatively cheap. Grandpas company bought the patent from the inventor for $25,000. Probably the greatest bargain of the twentieth century. Dad
Emulsion or Anfo !!!
Àlmost correct !
That is awesome story.
There’s plenty of different depths,patterns,and timing to use pending on depth and diameter per hole
Worked in Blasting for 8+ years in WV coal surface mining. Our normal depth was 70’-90’ to the coal. We stayed anywhere from 4’-6’ off the coal, to keep it from “shooting up” the coal. We used the same blasting materials. ANFO, the wet bags (premixed “blend” emulsion and ANFO) non-electric surface and down hole delays, boosters, the shot loader trucks, ect…. We had Infladec self inflating bags we used to separate the water and ANFO in the hole. Those emulsion bags would shove the water up the hole and you would still get your powder wet with out them. That’s why after the detonation you see the yellow smoke in the dust and white smoke. That is because it could not “burn” sufficiently and only partially ignite. Those yellow fumes are toxic! 🤮🤢
I always liked running 9ms across the face echelon and 100ms back the rows. Start it from the middle row. Worked pretty well. We held 8’ on stemming. My nearest structure was 2+ miles away. No seismograph or anything. I could load r high and let r fly!
I miss the job some days but when it’s winter time n -10* I don’t miss it at all! Those were fun times! Very hard work! Those guys earn there pay checks! I leaned so much in those 8 years. I don’t claim to gods gift to blasting at all! I was always open to other blasters ideas and ways. That was the fun in it. Always trying new things. That job location allowed me to try them. Since my lay off in 2015 I am sure there is all kinds of new technology out there. The unitronics (by Orica) was just being released b4 my layoff. The safety with it was awesome. Extra work involved scanning the time in for each down hole delay was tedious. But once they received the blast signal the wire could be cut and it would go off at that assigned time. That was a plus! Helps with a miss fire!
4:02 Three! Two! One! *DESTROY!!!*
Thanks for uploading!😇
Awesome shot! Did this for 7 years. Don't miss it anymore. Tired of dealing with the weather and to many headaches with all the regulations and and such.
Reminds me of my favorite bumper sticker... "There is no problem so great it can't be solved with sufficient explosives."
True. I must admit that.
It's fun man, the guys working here on this blast love their job
That fine rock used to backfill the drill hole is called stemming. The purpose is to keep the explosives under pressure so that they explode outward and break the rock. Without the stemming, the explosives would just blow right out of the hole when they go off.
PAmining makes sense
am mining engineer student,,need to know more about this mining operations
Done this before, on a lot bigger scale to get stone out for building wind turbine bases, 5 days drilling holes, 6 hours filling the holes with mix and boosters, 4 hours filling up with stemming on an awkward cliff edge from sacks due to the position we couldn't get a backhoe in and it took 4 days to take out the broken rock with dumpers and 50 ton machines, found some gold down about 15 meters as well
Proud To Be A Indian Miner.
I'm on powder crew on a strip mine in Kentucky. We use ANFO as well with Dyno Nobel boosters and shock tube detonators.
Knew of a company in Dublin Ohio that did road construction and mining work in Ohio and PA, I believe they may be long out of business, went to an auction at their Dublin location back in the 90's. they were selling off most everything. They had an ANFO truck and an explosives carrier truck for sale at this auction.
Brings a whole new meaning to the term BOOM truck
+davetileguy That's GOOD!
All I hear is the boomer from Gears of War saying "boom" lol. if you know how they sound then you know how amusing this is hahaha
Job satisfaction guaranteed! Not so much fun in the winter though.
That was a awesome video !
Kyle
Awesome vid!!!
man you gotta love your job!!
Awesome video! Still love the machines more but still very cool!
Wow, now that is cool! Its amazing how you can get right up close to all this stuff! Very dangerous too to say the least! Keep it up, I enjoy the videos!
1 word - AWESOME
Bloody fertilizer and a blast cap and BOOOOOOOM.
Science is cool.
Or fireworks and a whole warehouse of the stuff!
This sure brings back some fond memories.
+2nd Amendment Molon Labe Before or after the headache sets in.
Day or two of work, and 2-3 seconds of fun :) Blaster's life.
OverKillPlusOne so about how hard is it to get a job doing this? I'm really interested in maybe making a career out of this.
Awesome..Amazing Video
Yet another interesting video . Ah,blasting a man's favorite pastime.
I use to work for this company was there during that blast that day. All of the product being used is Austin Powder. Yes, it is some of the hardest work around, but would do it again in a life. These are true hard working people.
Steven Shaffer hardest work around? have you been underground charging?
Yes, I have...
A buddie of mines dad used to be the regional manager for Austin back in the day...he tried to tell bizzack no when they bout flattened grundy....smart ol dude
doesnt matter how many times i see a shot pulled its still cool as hell
wow very amazing
Great Vedios
first hand watched a many shot set off....even in the cab of earth moving equipment would shake as the shot went off....nice filming.
Supper amezing blast
thank very much
I used to work with a construction co that had drill and blast crew I asked him to call me before they shot I would go to the site to watch I was like a kid that never got old😂. They would use blast mats to cover after back filling the holes except this one time he pointed out a specific area to watch. As the blast went off this massive bolder 1/2 the size of a small compact car became airborne. He said keep your eye on it if it gets too close get under this dozer. I never seen nothing like that before. I was getting concerned but after it touched down we all laughed!
Thanks!
very good job.. steady..! thank you for sharing this video.. greetings from traditional Indonesian gold seekers ❤️👞⚒️⛏️🌼🌻👨🍳👍
So cool
Oh my god awesome
👌🏻👌🏻👍🏻👍🏻 you are great
Wow, I would have thought much deeper than that!
That’s a really big muzzle loader. Tightly packed with wads is just as important.
Good old amonia nitrate, dude chocked on smell of it
I worked on the river with bulk ships full of it
Velocidade da luz
Love your videos best on TH-cam in this category!!!
Amazing
Depends on the job, it can vary. Usually around 32'
Bruh this is hella good quality from 7 years ago
Yeah now I'm going to 4K lol
@@PAmining you replied on a 7 years old video
I am soo exclaimed bro 😄💓💓💓
Thats amazing
awesome
I used to haul that stuff from the plant in Carlsbad to the mine in colot 4000 gallons at a time twice a week
Thank you!!
Imaging standing in the radius of that explosion jesus
Awesome...👍👍
Nice
I'm guessing the ANFO is delivered binary and mixed on delivery into the hole with the bagged NH4NO3 being a booster.
Correct
Blasting work is fun for me :D I LOVE ANFO AND EMULSION
I just got a job doing this. It is very interesting.
Did anyone else see the det-cord go off right before the first explosion at 4:04?
You're seeing non-el shock tubing shooting between the holes. Very fun to watch, and they look great when replayed in slow motion.
+Craig Sutton I got to watch close up last week. Better and worse than electric but both work.
Yeeesss
No it hasen't, I normally upload weekly. Thanks
Thats right get them
THESE ARE SOME EXPLOSION!!!!
its been awhile since u uploaded a video & this is cool i always thot blowin up the ground was pretty cool.
Light it upppppp 🤙🏼🤙🏼🤙🏼
need a lanyard on that flash,light bro 25+ years drilling here
was that packaged emulsion in those sleeves loaded into the borehole before and after adding the booster? Then loaded with up with ANFO before stemming? sorry if my terms aren't right, I'm still learning this in school.
+lovesskiingpow lovesskiingpow Yes. That was put into the bottom of the holes where there was water. Emulsion is a water resistant explosive where ANFO is not. Thanks!
plus the packaged product at the bottom of the hole creates a better searing factor to maintain the floors.
Super
so cool. how could someone get a job doing that?
I didn't study anything and I got a job doing this. Only in Gold Fields Australia .😎
Blow some shit up
@Panagiotis Kagioudis I am also studying mining engineering
Let's be honest there's a lot of things and degrees but get your explosive license and an engineer's degree and minerals
im so glad you wrote up that description
Nice blast..
The most dangerous job 😂
How does one go about getting into blasting?
Seen this done many a time on strip jobs
GREAT VIDEO! for those of us who know little or nothing of the process a GREAT ADDITION would be for someone to give a simple narration or voice over about what we are see ( for instance what was that stuff they put in the whole?)
just the basics for us ignorant folk... but GREAT VIDEO. THANKS!
+bilbo Faggin's Absolutely! I'd like to do another more detailed blast video in the future and will be sure to put more work into narrating it
+PAmining---- cool thanks!
I'm looking forward to trying to do some hard rock mining out in the California Mojave desert - I want to use some ANFO....if it's legal. thanks again...great vids---keep'em coming!
How do you guys cut your delays? Say 20MS on your outside lines falling back to 50MS on your inside to fold the rock against itself?
non electric, ms 17, ms25 ms 42
Great! Anyone with information regarding the cost of quarrying without blasting and quarrying by blasting?
i just want to know it produce seismic wave or not after blasting
Great shot
now thats cool
Nice video
And you guys have such a different way of loading the holes... I'm Australian, here we just get 150 or 400 gram boosters, connect it to the leads, then just pour the amount of Ammonium Nitrate over and stem it... Do you always put AMFO in over the det ?
anfo,, ammonium nitrate with fuel oil
30' deep
Very interesting video, nice one, how deep are those holes on this particular blast?.
👌
It’s all in the back, forget the posterior chain.
What are they pouring into the hole around 2 minutes in? Water? This is my 3 year old daughter’s favorite video and she wants to know!
ANFO. Ammonium Nitrate Fuel Oil. That's the powder that creates the blast.
It's "ANFO".... Not AMFO... (Ammonium-Nitrate-Fuel-Oil) :)
appoint of correction
thumpin1 I thought ANFO was cap insensitive
Blasting anfo
What are those flashes on the surface right before the blasts? Are they some sort of indication mechanism by design, or was the intense light emitted from the blast strong enough to literally penitrate the thick layer of earth above and reach the surface?
Det cord
Non- electric shock tube. Not det cord.
Yes
I honestly don't know. Every shot is timed different
Wow
Hole titon drill and teamrock sir?
Makes earth quake for ourselves
Did you stem with residue from the drilling? (Not sure of the techical term in English) Never blasted coal, but in harder rock that would probably lead to poor fragmentation as most of the gasses vent up. No idea how deep these holes are or how much you stemmed.
Guessing no problem with water here, is it purely price that make you use ANFO instead of emulsion? Or is the rock to fragmented/layered (again no idea of English technical terms)
Normally the drill cuttings are used for stemming, however sometimes crushed rock is used. Water was a problem here, hence why the emulsion bags were used.
We always use crushed stone. But we shoot hard limestone and usually only 3 inch holes
No, that job is for the blast crew. Engineers design the blast pattern
That is deep, how many feet down did the blasting material go?
About 30 feet
Mybe arround 5meters
9 meters
i think im going back to school and for this. i have experience. oh the flashes through the line is not electricity, its most likely shocktube like primadet. it is tiny plastic tubing covered inside with a coating of most likely petn (my guess) w some aluminum and used to carry the flash impulse. depending on the mix, you can get the delay you want.
thats about how we do it at orica too but we dont use that much anfo anymore. we also have the new unitronics 600 coming out in this summer too. supposed to be better than the old 600's
What kind of wire do you guys use? I've done a couple firework shows and have always wondered what kind that is. I think I've used it once, but I forgot what kind it was, or what brand it was.
+Busdude97 I believe DYNO wire and connectors
Det cord
Interesting, I found DYNO nobel's web site and the product looked similar. Actually when I typed in det cord DYNO nobel was the first to come up. It looked like they also had one called shock line or lead line.
whats the point of covering the hole at 3:55? i mean its gonna get blown up anyways right?
flyrock prevention
that would be my ultimate job ever working in a mine working with explosive to bring thousands upon thousands of tons of earth to the floor
I think they drilled down around 30' to the coal on the first shot. I'm not sure about the other two. It varies depending on the job and how big of a lift the shovels can take off
hope you didnt have airblast problems that day boys!... stemming with cuttings is a good way to find 145db on the seismo surprised you only had as much ejection as you did, top loading the anfo looked like it was faster than pulling hose though! big holes too. just read your description and thought id chime in and let you gents know that boosters are made of a compound called PETN not ng. keep up the hard work gents. we all know someones gotta do it. if youre up in ontario workin sometime order some nordex product!
I work for that company, blaster holds like 15 ft on each hole
What depth are they typically running? 80'?
