Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.

This gas has, in many cases, a low calorific value and can be burnt in turbines and microturbines. If coal is gasified to produce syngas and then combusted to produce electricity, this results in a more clean process than combusting coal directly as a solid fuel. Syngas can be used also as a raw material, to produce hydrogen and methanol.
