shows a typical cross section of coal seams inter-spersed in layers of sandstone and shale. 1.2 Mining Methods Coal is mined by three methods: surface, under-ground, or in situ. The percentage of coal produced by each mining method can be identified from production statistics kept by the Energy Information Administration (EIA), a U.S. agency.Web
