Subsurface mining is a mining method in which soil and rocks are removed to reach underlying coal or minerals. It is used to mine ore deposits that are 50 m or more beneath Earth's surface. Room-and-pillar mining is a common method of subsurface mining. This method is used to extract salt and coal.Web

1. It's cheaper than other mining methods. At first glance, mountaintop removal might seem expensive. Explosives, for one thing, aren't exactly cheap, especially since millions of pounds are needed for a single mountain. The earth-moving machines used in digging up coal are also pricey, with some costing approximately $100 million.Web
