摘　　要：底板高承压水体上采煤的关键是确保在采动影响下底板岩层不突水.针对平禹一矿13091高承压水底板,采用直流电法三极探测技术对工作面两巷底板进行了探测,并对探测结果中存在的明显低阻异常区进行了详细分析,指出了工作面有突水可能性区域.据此提出了注浆改造深度、工作面加固范围等注浆加固底板的技术参数,并形成了一套适合本矿的注浆加固底板施工工艺.The key of coal mining below a high-pressured aquifer is to ensure that no water inrush from the floor will occur under the mining induced effect. Aiming at highly-pressured aquifer floor in working face No. 13091 of Pingyu-1 coal mine, we use the direct current sounding technology in drift of working face No. 13091 to probe the floor, obtaining that the floor has an obvious low resistivity anomaly. We analyze the low resistivity anomaly in detail and point out that the working face has the area where the water inrush is possible. On the basis of this, we put forward a technique suitable＇for reinforcing the floor of this coal mine, which includes the depth of grouting, and the scope of widening the working face.
