摘　　要：离层水害具有瞬时水量大、突水征兆不明显、危害大等特点,严重影响工作面的生产安全。以钱家营矿2075E工作面为例,结合矿井地质、水文地质资料分析,基于离层水致灾条件及水害类型,对该工作面进行了突水可能性判别及离层水害归类分析。研究表明:顶板离层突水致灾必须包括离层发育、离层积水、离层溃水等条件;结合离层突水特征将离层水害分为动水压力型离层突水、静水压力型离层突水、采动裂隙型离层突水三大类;分析得出钱家营矿2075E工作面发生离层突水的可能性较大,且突水类型为静水压力型离层突水。研究成果为矿井有效防治煤层顶板水害提供了理论与技术支持。The separated layer water hazard has the characteristics of large instantaneous water volume,no obvious phenomenons of water inrush,and great harm,which seriously affects the production safety of the working face.This paper taking the 2075E working face of Qianjiaying Mine as an example,combined with the analysis of mine geology and hydrogeological data,based on the disaster-causing conditions and water damage types of separated layer water,the working face is judged to be the possibility of water inrush and the classification analysis of separated layer water hazard.The results show that the disaster caused by roof separation strata water-inrush must include the conditions of separation development,separation area water,and detachment water outburst.According to the characteristics of separation water inrush,the water hazards of separation are divided into three categories that hydrodynamic pressure type separation water inrush,hydrostatic pressure type separation water inrush,and mining fracture type separation water inrush.And the analysis show that the possibility of separation water inrush in the working face of Qianjiaying Mine 2075E is relatively high,and the water inrush type is hydrostatic pressure type separation water inrush.The research results provide theoretical and technical support for the effective prevention and control of coal seam roof water damage in mines.
