工作面内隐伏含水体电法探测的实验研究

he hidden water-bearing bodies or water-bearing structures in working face are one of the main causes of the water disaster in working face. In order to detect the water-bearing bodies under the floor of working face, a new DC detecting method, that is, the parallel bipole-dipole resistivity method was introduced. The physics simulation experiment was made. The modeling test was carried out in a big water tank. The iron block was used to simulate the water-bearing body in working face and the water to simulate the surrounding rock mass of the roadway. In the data processing and interpretation, this paper provided the resistivity computerized tomography method (RCT) to inverse the position of the target body. The modeling experiment in the water tank indicated that it is feasible and valid with the bipole-dipole method in detecting the hidden water-bearing in working face, and it would have a promising future for its obvious virtue of amplified observation signals and adaptive range.
