摘要
针对麻家梁煤矿14104-1回采工作面异常涌水情况,为查找工作面出水水源和导水通道,通过施工探查钻孔,结合出水区域地质及水文地质条件,从含水层水位、水质及导水通道3个方面进行综合分析,开展奥灰突水机理研究,并对涌水通道进行注浆治理,结合注浆情况及涌水量变化,最终确定此次涌水水源为奥灰水,涌水通道为断层裂隙导水。通过对涌水区域底板隔水层内导水通道进行注浆治理,达到封堵导水通道目的,降低突水风险,实现工作面安全回采。
In view of the abnormal water inflow in No.14104-1 mining face of Majialiang Coal Mine,in order to find the water source and water conducting channel of the working face,through the construction of exploration drilling,combined with the geological and hydrogeological conditions of the water outlet area,the water level,water quality and water conducting channel of the aquifer were comprehensively analyzed.The mechanism of Ordovician limestone water outburst was studied,and the grouting control of the water channel was carried out.Combined with the grouting situation and the change of water inflow,it was finally determined that the water source was Ordovician limestone water and the water channel was fault fissure conducting water.Through the grouting control of the water conducting channel in the floor aquiclude of the water inflow area,the purpose of plugging the water conducting channel was achieved,the risk of water outburst was reduced,and the safe mining of the working face was realized.
