Massey Energy Company (Massey) produces, processes and sells bituminous coal of steam and metallurgical grades, primarily of a low sulfur content, through its 23 processing and shipping centers, called Resource Groups, many of which receive coal from multiple coal mines. At January 31, 2009, the Company operated 66 mines, including 46 underground mines (two of which employ both room and pillar and longwall mining) and 20 surface mines (with eleven highwall miners in operation) in West Virginia, Kentucky and Virginia. Massey generates revenues through the mining, processing and selling of steam and metallurgical grade coal, as well as through other coal-related businesses, including the management of material handling facilities and a synfuel production plant. Massey produces coal using four distinct mining methods: underground room and pillar, underground longwall, surface and highwall mining.
