  • Colliery: How Coal Mining Works? - Science ABC

    11/12/2018  Coal mining (also called colliery) is the process of extracting coal from the ground’s surface or from deep underground. Coal miners literally raze entire mountain ranges to feed our insurmountable desire for cheap energy. There’s something brutally simple about coal mining. Take away the monstrous-but-sophisticated machinery and eco-friendly-but-incredulous marketing jargon

  • Coal Mining and Processing Energy Trends Insider

    Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground’s surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining
