摘　　要：煤矿智能化、无人化开采迫切需要水害隐患地质透明化为其保驾护航。近年来,音频电透视技术大量应用于鄂尔多斯盆地北部区域的煤矿井下工作面顶板防治水工作中,并在煤矿工作面顶板富水区探测应用中取得了较好的效果。本文针对某矿3-1上201工作面回采过程中的顶板水害问题,首先建立了矿井音频电透视三维正反演模型,对算法的有效性进行了验证。在工程中对工作面顶板上方120m范围内可能存在的砂岩富水区进行探测,并对探测成果进行三维成像显示,最后对工作面顶板疏放水钻孔涌水量和音频电透视探测的富水异常区进行了对比。探测结果共划定3个富水异常区域,经疏放水钻孔验证,取得了良好的效果,对透明工作面的建立具有重要意义。The intelligent and unmanned mining of coal mine urgently needs the geological transparency of water hazard to protect it.In recent years,audio-frequency electro-perspective technology has been widely applied to the roof water prevention and control of coal mine working face in the northern area of Ordos Basin,and has achieved good results in the exploration application of coal mine working face roof water-rich area.Aiming at the problem of roof water disaster in the mining process of No.In view of the roof water damage problem in the process of mining on No.3-1201 working face of a mine,this paper firstly establishes a three-dimensional forward and inversion model of mine audio electrical perspective,and verifies the validity of the algorithm.In the project,the sandstone water-rich area which may exist in the area of 120 m above the roof of the working face is detected,and the detection results are displayed by three-dimensional imaging,finally,the water inflow of drainage borehole in the roof of the working face is compared with the abnormal area of rich water detected by audio-frequency electric perspective.The detection results have been divided into 3 water-rich abnormal areas,which have been verified by drainage boreholes and achieved good results,which is of great significance to the establishment of transparent working face.
