Surface mining is the technique used when coal is found near the surface. Underground mining is used to extract coal lying deep beneath the surface. Surface mines use large earth-moving equipment, such as draglines, shovels and loaders. Underground mines use longwall systems or continuous miners.
Fifty years ago when most coal mining was done manually, underground mines accounted for 96 percent of the coal produced each year. Today, almost 60 percent is produced from surface mines. Most underground mines in the United States are located east of the Mississippi River, although there are some in the West, particularly in Utah and Colorado.

Coal mining | World Coal Association
Coal is mined by two methods: s urface or 'opencast' mining or underground or 'deep' mining. The choice of mining method largely depends on the geology of the coal deposit.
