While numerous mining companies still conduct surface mining in their sites, the costs that come along with it may become prohibitively expensive on the long run. One particular indicator is the strip ratio, or the number of waste materials in units that a mine site must remove in extracting one unit of ore. Mining companies seeing a larger strip ratio can then turn to underground mining as a more cost-efficient and land-friendly investment. The Objective of Underground Mining What underground mining does is to extract the ore from the earth in a safe and economical way without producing too much waste. Underground mining is particularly feasible for mining companies specialising in the extraction of minerals, rocks, and precious stones that are found far beneath the ground. This is also an effective option for companies mining rocks or minerals on the side of a mountain.
