Dirty Great Machines - Down-The-Hole Drilling | Technology Documentary | Reel Truth. Science

Kidd Mine in Ontario, Canada plunges 200 miles underground and is the deepest base metal mine in the world. The miners use a technique called blast hole mining to extract metal and use state of the art Down-The-Hole Drills located beneath the surface to make holes at almost any angle.

peters is so good at explaining how do they drill, as a layman i understood almost everything he explained

[exploringabandonedmines]

Looks a lot safer than the 100 year old mines we visit underground!

[tiny]

I really like James he explains the process really well for everyone to understand how it all gose down underground

You guys have big balls going 12 and a half miles down in the darkness...
I spit my balls up and out my mouth. Gagged and farted, watching this, not to mention the claustrophobia.
What's the song?
"Take this job and shove it!!!"
Seriously though. Kudos to you guys that can handle this kind of work.
I know my limits.

Mother Earth is so beautifully amazing

40:28 Lol some dude in the background playing Space Cadet Pinball

[wiesemarius]

not the deepest mine in the world. I think the Kidd mine is 7th if I am not mistaken. South Africa has the top 5 deepest mines in the world

We mine 75% of the salt and leave 25% for pillars. What happens after the mine is no longer producing and is abandoned. Will the mine flood and collapse after water washes away pillars, causing mayhem on the surface above?

For all the mines in operation, you need experienced people to run the machinery and equipment.
In my hometown, the german Freiberg there is located the first and oldes mining academy in the world. 850 years ago, silver was found near the surface. This was the beginning of the silver rush in Freiberg. In 1750 the mining academy was founded to make the underground mining more safe and more efficient.
The mining academy was the mother of all mining methodes we using in the present time. The old silver mine is now part of the academy. The students can using the stopes for practice her knowledge. This is unique in the world.
In the 850 yeras, more than 64 million tons of rock was mined. The output of pure silver was more than 6000 tons. For 200 years Freiberg was the richest city in Germany. The silver exploration ends in 1912 but the History of mining is present everywhere in the City.

In potash and salt mines the equipment dies when you take it out of the mine.

[volt-u]

modern technology? Czechoslovakia has been using this method for 50 years

[daretolive]

Island Nation With tons of salt on the roads. I would wager their cars rust pretty fast.

[breakalegfpv]

if they haven't struck oil yet ? they never will. LOL

[cpcattin]

Heavier than 6 African bull elephants. ! ?? How much is that in giraffes ?😊

[lewymartain]

They are Amazing, they made that Robot look like a girl even with a ring in her lip. Pity they couldn't get her speaking voice to sound more human ????

200miles!🤣😂 That's what I was thinking. Been to the bottom of #4&was bolting in 9800 Station before it broke into ramp. Pressures are crazy, "Unopened bottle of water, the label was loose around the bottle before opening the bottle". That's how much pressure on the body, "for the kiddos out there". And using a jackleg and stoper, in 48°c plus 100% humidity. Like working out for 10.5hrs straight while in a sauna sucking dust from a vacuum as a breather hose, mixed with blue diesel fumes. Enjoy.. ALL TRUTH, EVERY WORD.
