摘　　要：为了摸清矿井周围地下水赋存规律,解决矿井涌水问题,以鸟山矿风井为例,采用激发极化法对井筒周围地下水进行勘测,并结合工程地质资料对勘测结果进行解释,得到矿井具体的含水层埋深、厚度以及涌水量结果。与实际情况对比表明,激发极化法由于不受纯地形起伏及围岩电阻率不均匀性的影响,因此在矿井地下水勘探方面具有良好的可靠度。用测水结果指导井筒施工,不仅可为矿井建设提供安全保障,还加快成井速度。激发极化法还可以对已完成注浆的井筒进行效果检查,评定注浆堵水的质量,具有普遍推广意义。In order to determine the occurrence of groundwater around the mine and solve the prob lem of mine water inrush, Niaoshan coal mine air shaft is used as an example to survey the groundw ater around the shaft by applying the induced polarization method. By combining engineering geolog ical data, the survey results are interpreted to obtain the depth and thickness of the aquifer and water inflow. Compared with the actual results, the induced polarization method is quite reliable in the mine groundwater exploration because it is not affected by pure undulating terrain and surrounding rock resistivity heterogeneity. By using the exploration results to guide shaft construction, it not only provides security for mine construction, but also accelerates well completion. The induced polariza tion method can also be used to check the effect of the shaft where the grouting is completed and as sess the quality of the grouting. Therefore this method has the potential of application in broader area.
