针对张村矿断层突水问题,分析了矿区断层分布规律,利用距离判别法对张村矿主要断层的突水等级进行了判别分析,结果表明:因煤层与太原组石灰岩之间的隔水层太薄,小于底板采动破坏深度,太原组石灰岩水比寒武系石灰岩水更容易发生突水;断层落差越大,在高水压作用下突水或涌水量会越大,其富水性会越强。分析结果与矿区实际情况和瞬变电磁探测结果是吻合的,并根据研究结果提出矿区断层突水防治措施,对于矿井安全生产具有一定的指导意义。
According to the water inrush problems of the fault in Zhangcun Mine, the paper analyzed the distribution law of the faults in the Mining Area. A distance judgment method was applied to the judgment analysis on the water inrush grades of the main influence faults. The results showed that due to a water isolation layer between the seam and Taiyuan Formation limestone was too thin and less than the mining failure depth of floor, the water in the Taiyuan Formation limestone would be easier to case a water inrush than water in Cambrian limestone. The higher of the fault drop, the higher of the water inrush or a water inflow quantity would be under the high water pressure role and the watery would be higher. The analysis results and the actual conditions in the mining area as well as the transient electromagnetic exploration results could be fitted. According to the study results, the water inrush prevention and control measures of the mining area were provided and could have certain guidance significances to the mine safety production.
