摘要
范各庄矿北翼水文地质条件复杂,煤系基底奥灰富水性强,发育有断裂构造、岩溶陷落柱等垂向构造,因此,奥灰水为该区域重点防范对象。为确保安全生产,分析评价了煤矿开采中是否存在突水危险,提出防范水害发生的技术措施。
Hydrological condition is complicated at North wing of Fangezhuang Mine.Ordovician limestone groundwater-bearing there was strong at coal measure basement,and vertical structures such as fractural structure and karst collapse column developed.Therefore,Ordovician limestone water is focal objects to be guarded in this mining area.In order to guarantee safety production,this paper analyzed and evaluated whether there were water-burst danger potentials during mining,proposed technical measures to prevent water disaster.
