There are five geological provinces in the western states from which 100 percent of the lignite and sub-bituminous coal comes. Part of just one province, the Northern Great Plains, has recoverable reserves of lignite and sub-bituminous and bituminous coal which account for 44 percent of the nation's total. Most of western coal is low in sulfur and, therefore, in demand by utilities who must comply with the Clean Air Act. It lies in thick seams appropriate to surface mining methods. With a majority of coal reserves available in the West, several new mines are in planning stages. The article looks briefly at some of the aspects of mine planning which must be considered.
