【摘要】 为探明工作面底板内隐伏含水体,研究利用一种新的直流电法——平行双极-偶极电阻率法——进行探测.采用物理模拟方法,实验模拟在大型水槽中进行,利用铁块模拟含水体,水模拟围岩.在资料处理解释方面,采用电阻率层析成像反演计算目标体的位置.实验表明,采用平行双极-偶极电阻率法探测工作面内隐伏的含水体是一种行之有效的方法,该方法也因其观测信号强、适应范围广的优点,具备广阔的应用前景.更多还原

【Abstract】 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,the resistivity computerized tomography method(RCT) to inverse the position of the target body was provided.The modeling experiment in the water tank indicates that it is feasible and valid with the bipole-dipole method in detecting the hidden water-bearing in working face,and it has a promising future for its obvious virtue of amplified observation signals and adaptive range.更多还原
