针对矿井工作面内底板水害,可利用井下电法穿透技术进行有效探测.利用双巷音频电透视技术和双巷三维并行电法技术在淮北某矿Ⅲ631工作面底板进行探水,实践表明:两种探查技术各有特点,其中双巷音频电透视技术发收分离,采集数据量有限,其探测结果的收敛性稍差,对工作面内底板赋水区定位范围大,适合于进行大范围勘探;双巷三维并行电法技术数据采集量大,目标体收敛性好,其对工作面内底板赋水区的空间范围判断准确,适合于进行精细探查.

@@@@Underground electrical penetration technique can be used to effectively detect water hazards in working face floor. The field detection results which were obtained by the two-entry audio-frequency electrical penetration and two-entry parallel 3-D electrical method in Ⅲ631 working face in a mine of Huaibei Mining Group showed that the two detection techniques have their own characteristics:the tow-entry audio-frequency electrical penetration is suitable for a wide range of exploration by collecting limited data with sending and receiving separation,having bad convergence of the detection results and a large location for containing water in working face floor;the two-entry parallel 3-D electrical technique is suitable for fine exploration by collecting massive data,having good convergence of the target body and accurate judgment on the spatial range of the water-containing zone in working face floor.
