Abstract
An investigation was made of ground response to pillar retreat mining in a 5.5-Foot-thick seam at 600-foot depth at a site in northern West Virginia. This paper describes mining-related stress changes and movements at mine level, displacements within the overburden, and ground surface subsidence and ground water level variations. Hydraulic properties of the rock strata were found to change and water levels decline in certain deep-lying strata.
