As the large coal reserves are depleted, the coal industry is forced to explore smaller coal seams with lower cover. The strict environmental regulations in today's coal industry will soon influence or prohibit mining the smaller, shallower coal reserves due to the land surface and subsurface subsidence affects from undermining. Therefore, an analysis of surface and subsurface affects has been conducted in to better understand the relationship between the subsidence mechanism and hydrological impact of subsidence in areas with low cover.;A field study near Waynesburg, Pennsylvania was undertaken from 1998 through 2004. The hydraulic pressure heads in the local aquifers were monitored and recorded by 30 piezometer wells in 8 locations over a 9 panel longwall district. The Laurel Run stream located directly above the longwall district was monitored by 16 stream flow stations. Precipitation data was considered during the analysis.
