Abstract
The United States has very large coal reserves in seams that are less than 1,065 mm (42 in) thick. These reserves are often not mined because of the difficulty of working in low heights; also, in most cases, the seams are beyond the technical or economical limits. The U.S. Bureau of Mines is attempting to develop new techniques for mining 150- to 1,065-mm (6- to 42-in) thick coal seams. Research has focused on existing thin-seam mining techniques, testing of small- and full-scale physical models of the Bureau's slot mining concept, and computer modeling of the full-scale process.
