为准确预报矿井工作面底板异常体，依据并行电法技术原理，提出了构建三维测试系统，利用立体电法反演成像进行地质异常体及富水性解释的方法。根据两淮地区，矿井主要受奥陶纪灰岩水威胁的情况，建立了模拟工作面内部隐伏低阻异常特征的三维地电模型，探讨其立体电法探测地质异常体的可行性和有效性。仿真计算结果表明该技术对低阻异常具有较高的分辨能力。该方法应用于安徽某矿工作面东二B组采区，成功的探测出采区内1#陷落柱与裂隙发育范围及其含、导水性。

To accurately predict mine working face floor anomalous body, based on parallel electric method principle constructed 3D test system, a method of geological anomalous body and water yield property interpretation through stereoscopic electric inversion imag?ing put forward. Coalmines in Huainan and Huaibei areas have been mainly threatened by Ordovician limestone water, thus a 3D geo?electric model to simulate working face insidious conductive anomalous features has been modeled, from this carried out stereoscopic electric prospecting feasibility and validity studies. The simulated computation results have demonstrated the technology ’s higher reso?lution capability in conductive anomalous feature identification. The method has been used in east IIB winning district of an Anhui coalmine, successfully detected subsided column No.1, fissure developed scope and their water-bearing property, water conductivity.
