摘要
灵北煤矿51001综采工作面属于带压开采。以51001综采工采面布置的探测钻孔探测成果为依据,对煤层底板灰岩含水层及隔水层情况进行综合分析,并采用突水系数法对该采面开采安全性进行评价。51001综采工作面底板突水系数为0.036 MPa/m,小于《煤矿防治水规定》规定的0.06 MPa/m,采面带压开采相对安全。但工作面开采遇断层破碎带时仍存在突水可能,建议采用底板注浆、强化排水能力等措施进行防治水。
Based on the borehole exploration results at 51001 fully-mechanized working face of Lingbei Colliery,the author makes an evaluation of mining safety with water inrush coefficient method by comprehensive analysis of the aquifer and aquiclude of floor limestone,which shows that water inrush coefficient of floor is 0.036 MPa/m,less than 0.06 MPa/m specified in“Regulations of Water Control in Mine”;mining under pressure is relatively safe but with a possibility of water inrush when crossing fault fracture zone,and proposes the water control measures of floor grouting and drainage capacity reinforcement.
