1. Southern Ohio Coal Company, Athens, OH (United States)

Southern Ohio Coal Company`s (SOCCo) Meigs Division, a part of American Electric Power`s Fuel Supply Division, is located in the southeastern Ohio counties of Meigs and Vinton, and consists of two large underground mines and a central coal preparation plant. The division began mining the 54-inch Clarion 4A seam in the early 1970`s, with three underground mines, which first used conventional mining, but changed to continuous mining after only a few years. Longwall mining began in 1978 at the Meigs No. 2 Mine. In 1989, Meigs No. 1 and Raccoon No. 3 Mines were interconnected underground, with the combined mine being named Meigs No. 31. A longwall was installed in Meigs No. 31 in September 1989. The Meigs Division operated three longwalls until 1993, but then reduced to two longwalls (one at each mine) and five continuous miner sections, which are used solely to develop main entries and gateroads for the longwalls. Longwall panel size has steadily increased through the years, growing from the initial 500 ft. wide by 5000 ft. long panels to the present panels which range from 900 to 1100 ft. wide by 10,000 to 13,000 ft. long.
