摘要
乌兰煤矿北二采区与几个地方小煤矿毗邻,因采空区的边界及含水性情况不明,严重影响采区的设计,同时老窑采空区严重地威胁着矿井的生产与安全。本文介绍了应用三维地震及电磁法探测采空区边界及含水性的技术方法与地质效果。
The north second mining section of Ulan Coal Mine Company adjoins to several small local coal mines. Owing to the borderline of mined-out areas and the water-bearing zone are unknown, the design of the area is deeply influenced, and the old mined-out area threatens the production and safety of the mine. The method for the exploration of the mined-out areas by using 3D seismic and electromagnetic laws and its effect are introduced.
