What is coal used for? USGS
Coal is primarily used as fuel to generate electric power in the United States The coal is burned and the heat given off is used to convert water into steam, which drives a turbine In 2012, about 39 percent of all electricity in the United States was generated by coalfired power plants, according to the US Energy Information AdministrationCoal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after miningCoal mining | World Coal Association

CDC Mining How Does Limestone Rock Dust Prevent Coal
Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone) If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sinkCoal mining was able to use steam to go deeper than ever before, getting more coal out of its mines and increasing production One key factor to these engines was they could be powered by poor quality coal, so mines could use their waste in it and sell their prime materialCoal in the Industrial Revolution ThoughtCo
