What is the difference between underground mining and open pit mining

Aside from being a beautifully polished gem, diamonds are also used to cut, grind or drill other materials. Underground mining uses different underground mining techniques to excavate hard minerals, such as ore which contains, gold, copper, silver zinc.

Mining is important to the South Africa Economy. Not only is gold one of the biggest exports it also creates one million jobs. To view more articles, please visit the Leads 2 Business Blog.

Supports move forward as coal is extracted. The roof collapses behind. Longwall is much more efficient than bord-and-pillar because it collects more of the coal instead of using it for support. The two methods of mining will continue to be used. Technology and innovation from companies like Bend-tech will keep advancing these methods as the industry moves towards better safety practices and greater efficiency.

Over the past century, the mining world has taken full advantage of amazing technological advances and innovation. Today, instead of using candles and canaries, miners use LED integrated explosion-proof cordless mining headlamps and multi-purpose gas detection sensors. However much technology mining now incorporates, the basic idea behind the act of mining remains the same: something you need is in the ground and you have to find a way to get it out.

As one might expect, there is a wide variety of mining methods available today; yet when it comes down to it, all of them can be split into two basic categories: underground mining and open pit mining.

As its name indicates, open pit mining is a method of extracting rock or minerals from open pits, like quarries and burrows. Underground mining Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible.

Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. What is underground mining?

Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. Our products.
