By the 1940's, surface mining of coal had become an important in­ dustry in the area. The disturbance of earth materials during surface coal-mining operations exposes iron sulfide compounds which increase dissolved solids in streams. In addition, the exposed materials become more easily eroded and sediment loads of streams are increased. TheMine Subsidence - Kentucky,longwall mines (which are designed to remove large blocks of coal across long distances) generally occurs as the longwall panel advances or shortly after.
