Modern strip mining is heavily mechanized and employs as few people as possible. Strip mining companies do not hire nearly as many miners as traditional deep mining 300 ton drag scoops and town-house sized bulldozers now do the jobs that used to employ miners.

The effects of this damage can continue years after a mine has shut down including the addition to greenhouse gasses death of flora and fauna and erosion of land and habitat.
Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips.

The actual mining occurs at this step. It is done in a narrow strip in an elongated form. First the primary strip is mined for coal. After it is extracted thoroughly the second strip is created by removing filth rock and waste from the top. This debris is dumped on top of the first and used strip. The process repeated till the last strip is
