Today surface mining equipment is capable of removing overburden to mine coal seams approaching 200 feet in depth. However, because a large portion of the surface reserves has already been removed, in the future surface mining activities are expected to decline, accompanied by a resurgence of underground mining in deeper coal beds. In fact, this
