摘　　要：东山井田位于娘子关奥陶系岩溶泉域的西部。奥陶系灰岩水已严重地威胁着 15号煤层的安全开采 ,在底板隔水岩柱薄弱地带或断裂陷落柱构造破碎带 ,存在着岩溶水突破相对隔水层溃入矿坑的可能性。本文着重研究了底板突水条件 。Dongshan Coalfield is located in the western part of Niangziguan Spring Area.Ordovician karst water threatens mining No.15 coal seam safely.The possibility of karst water gushing is existed in weakness zone of water resisting coal block and fractured zone of collapse columns.This paper deals mainly with the condition of water gushing from coal seam floor and advances the control measure.
