摘　　要：以郑煤集团某矿为例,通过对工作面底板进行瞬变电磁法和无线电透视法探测,分析煤层底板的赋水性及导含水构造。研究结果表明:物探范围内煤层底板-45 m处低阻区岩层赋水性相对较弱,该区域对安全回采影响偏小;煤层底板-70 m处岩层存在20处低阻异常区域,O_2灰岩含水层发生底板突水的可能性较大,必须对底板进行注浆加固。最后以现场断层揭露、钻孔出水量和水压,说明该工作面综合物探结果的可靠性。Taking a mine of Zhengzhou coal and electric power group corporation Ltd. as a test mine, the transient electromagnetic method and the radio perspective method were applied for analyzing the floor structure and water abundance. The results show that there is little influence to mining safety on the rock strata 45 m below coal seam. There exists 20 low-resistivity areas in the rock strata which is 70 m below coal seam, water inrush from O2 limestone aquifer is likely to happen during the mining, and it is necessary to take floor grouting reinforcement measures. Finally, the reliability of the comprehensive geophysical results is explained by fault exposure, water flow and water pressure of drilling.
