摘要: 为了优化采区底板岩层赋水性的探测效果，基于电透视法和高密度电法，结合全电场空间电位分布理论，提出一种以轴向单极-偶极法为底层装置、三维供电组合为供电装置、多通道采集工艺为测量装置的高效、立体底板探水系统。结果表明：采用此探水系统能够大幅度提高矿井物探效率，精准探查工作面附近岩层任一位置、任一深度的赋水性分布情况，划分底板岩层的贫、富水区域，评价工作面的安全性，实现工作面底板赋水性的全区域、无盲区、三维立体探测。Abstract: In order to optimize the detection effect of water-bearing capacity of lower strata in the mining area, based on the electric perspective method and high density electric method, combined with the spatial potential distribution theory of the whole electric field, an efficient and three-dimensional floor water detection system was proposed. The system takes the axial unipole-dipole method as the bottom device, the three-dimensional power supply combination as the power supply device, the multi-channel acquisition technology as the measuring device. The results show that using the water exploration system can greatly improve the mine geophysical exploration efficiency, accurately detect the water-bearing distribution of the rock stratum at any position and at any depth near the working face, divide the poor and water-rich area of the floor rock strata, and evaluate the safety of the working surface. It can realize the full area, no blind area and three-dimensional detection of water-bearing capacity on the bottom plate of the working face.
