Mining Hydrogeology. Surface and underground mining dewatering operations may alter natural groundwater and surface water flow systems. Such operations require specialized water-handling procedures to minimize impacts in areas underlain by solution-prone carbonate rocks (e.g., limestone quarries) and underground mine pools/voids and adjacent to sensitive surface water features.

Abstract. Although all deep mining has now ceased in the Durham coalfield of northern England, dewatering still continues (in June 1995) in the central area of the Coal Measures outcrop.Beyond the radius of influence of the dewatering pumps, the water table has already recovered, and several uncontrolled minewater discharges are found.
