Surface Coal Mining | West Virginia Coal Association

Surface coal mining techniques, which account for the majority of national coal production and roughly 42 percent of West Virginia’s coal production, involve the mechanical removal of overlying native earth and rock or “overburden” to reach underlying coal seams Surface mining can be further categorized into three basic operational methods:Coal Mining and Processing | Energy Trends Insider,Surface mining can be used when the coal is buried less than 200 feet underground In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal Once the mining is finished, the dirt and rock are returned to the pit, theCoal mining | World Coal Association,Surface mining Once the coal seam is exposed, it is drilled, fractured and systematically mined in strips The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used
