While underground mining, which allows coal companies to extract deeper deposits of coal, is viewed as less destructive than strip mining, the effects of mining widespread damage to the environment.

Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them
Surface mining can be accomplished by the following main methods: Openpit Mining: Removing ore to leave a crater. Quarrying: An openpit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are:
Surface mining at these scales is more economical for coal companies, safer for miners, and, coal operators say, essential for mining the thin seams of lowersulfur coal more valuable in today's market. With dynamite and immense machines, surface mines can produce more than two to three times as much coal per miner as underground mines can.
