摘　　要：根据国家能源集团宁夏煤业有限责任公司红柳煤矿水文地质条件,井下巷道施工采用瞬变电磁法探测工作面顶板含水层富水区,结合地面钻孔窥视法确定工作面顶板覆岩破坏“两带”高度。技术人员制订了对顶板砂岩含水层水超前预疏放水方案,采用定向钻机施工疏水钻孔提前疏放水,为工作面安全、高效回采创造有利条件。According to the hydrogeological conditions at the Hongliu Coal Mine of CHN Energy Ningxia Coal Industry Co.,Ltd.,aquiferous zone in the roof of working face is detected using the transient electromagnetic method for underground construction,and the height of"two zones"of overburden failure on the roof of working face is determined by the surface borehole peep.Technical personnel develop an advance predrainage scheme for sandstone aquifer in the roof,and drain water in advance through the drainage borehole constructed using directional drilling machine,thus creating favorable conditions for the safe and efficient mining of the working face.
