coal - Problems associated with the use of coal | Britannica

Methane may be extracted from coal beds prior to mining through the process of hydraulic fracturing ( fracking ), which involves high-pressure injection of fluids underground in order to open fissures in rock that would allow trapped gas or crude oil to escape into pipes that would bring the material to the surface.

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.
