摘要 矿井工作面底板探水电法穿透方式较多,且特点各异。通过室内实验模拟井下常用的单极—偶极法、平行双极—偶极法以及双巷并行电法技术,分析三种探测方法的优缺点,为工作面底板水害实测提供参考。结果表明:三种方法采集数据各有特点,对于异常体均有反应。单极—偶极法采集数据量有限,其探测结果的收敛性稍差;平行双极—偶极法数据采集量较大,但数据采集效率相对较低,施工时间长,适合进行小范围探测;双巷并行电法技术的数据采集量大,数据采集效率高,目标体收敛性好,其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。 There are many electricity penetration methods with different characteristics for detecting the floor-water hazard in the working face. Through the laboratory test by simulating monopole-dipole method,parallel bipolar-dipole resistivity method and parallel electrical method,the authors analyzed the advantages and disadvantages of these three kinds of detecting methods so as to provide reference for detecting the floor-water hazard in the working face. The results show that the three methods have their respective characteristics and reactions to anomalies. The monopole-dipole method has less convergence of the detection results,and the quantity of data collected by this method is limited; the parallel bipolar-dipole resistivity method characterized by relatively low data-collecting efficiency and long construction time is suitable for small range exploration by collecting massive data; the parallel 3D electrical technique of lane pairs is suitable for meticulous exploration because it can collect massive data,has good convergence of the target body and can accurately determine the spatial limits of the water-bearing district on the working face floor.
