摘要
小煤窑破坏性无序开采,造成了许多采空区,给红会三矿八采区生产带来安全隐患。采用电法探测手段,根据研究区的地质概况确定了区内不同地层的电性特征,查明了该区内采空区的分布范围、小窑采空区的边界线、采空区的埋藏深度以及积水情况。与实测资料对比,探测精度在允许范围内,为该区井巷掘进工作提供可靠的技术支持和安全保障。
The destructive and disorderly operation of the small coal mines results in a lot of work-out sections creating hidden troubles for the eighth mining section of Honghuisan mine. The electric characters of different stratum in the research section are confirmed on the geology general situation and the boundary, embedding depth and seeper of the work-out sections are detected by electric method. And compared with the measure data, the detection precision is high enough to provide reliable technical support and safe guarantee for the operation of the sections under study.
