摘要
Abstract
New iron mine is a typical north China type coal ifeld, the underlying ordovician limestone karstic ifssure aquifer is development, karst groundwater, the storage conditions good, rich water is stronger, and the higher conifned water head. Full of mining area is under pressure mining. At the top of ordovician , the existence of ancient weathering crust increased between coal seam and aquifer thickness of water-resisting layer; at the same time as a result of the existence of ancient weathering crust, to think the guide height and pressure guide litres height is zero. The two factors of under pressure mining for coal mine has important hydrological geological effect.关键词
