coal mining Definition, History, Types, Facts

2021-7-21  Coal mining, extraction of coal deposits from the surface of Earth and from underground.. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal ...

Coal Mining - an overview ScienceDirect Topics

Coal mining operations reduce coal seam gas pressure and induce fractures in the surrounding strata, which increases gas emissions from longwall workings and surrounding coal seams. Efficient utilization of effective methane co-extraction during mining helps prevent possible gas explosions and outbursts, providing a safer, more productive coal mining environment.

Coal National Geographic Society

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
