the coal in the production process

Coal minersuse giant machines to removecoalfrom the ground. They use two methods: surface or underground mining. Many U.S.coal bedsare very near the ground’s surface, and about two-thirds ofcoal productioncomes from surface mines. Modernminingmethods allow us to easily reach most of ourcoal reserves.
