摘　　要：为了解决内蒙古盛鑫煤矿51203回采工作面上部4号煤采空区积水区域不明,影响该工作面回采安全的问题,利用井下幅频电透视技术对51203工作面上部4号煤采空区积水进行针对性探测,通过前期物探设计,中期工作面现场数据采集,后期室内数据处理解释,圈定出了工作面上部4号煤采空区积水的位置及影响范围。盛鑫矿根据这一物探成果,采取提前打钻放水等针对性措施,对工作面上覆4号煤采空积水区进行处理,消除了工作面顶板采空区突水对工作面回采所造成的威胁,取得了良好的效果。In order to solve the problem of water accumulation in the No.4 coal goaf in the upper part of the 51203 mining face in Shengxin Mine,Inner Mongolia,which affected the mining safety,No.4 coal in the upper part of the 51203 working face was mined with underground frequency electrical perspective technology.The water accumulation in the area was targeted for detection.Through the early geophysical design,field data collection in the mid-term working face,and indoor data processing and interpretation in the later period,the position and influence range of the water accumulation in the No.4 coal goaf in the upper part of the work face were delineated.Based on the results of this geophysical survey,Shengxin Mine adopted targeted measures such as drilling and releasing water in advance to deal with the No.4 coal seam goaf water accumulation area on the working face,which eliminated the safe mining of the working face due to water inrush from the roof goaf of the working face,with good result.
