  • Open Pit Mining Techniques

    Open-pit Mining Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

    'The Trend's first open-pit mine came in 1965, but it was the steep rise of gold prices in the 1980s and the introduction of cyanide heap-leaching that made mining such low-grade ore profitable.' 'Additional drilling at the site of the proposed open-pit mine allowed the company to increase its estimates to roughly 26 tons of gold, it said in a statement.'

    In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.
