Commonly used mining techniques to extract coal ICSC:

Jan 25 2018 Underground mining is more widely used to extract coal compared to opencast mining as many coal seams are said to be found deep below the earth surface. The underground mining includes six type of mining methods that include longwall mining continuous mining room and pillar mining blast mining shortwall mining and retreat mining.

What is coal used for USGS:

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants bituminous coal subbituminous coal or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam which drives a turbine which produces electricity. In 2019 about 23 percent of all electricity in the United
