摘　　要：以内蒙古乌海天誉煤矿9#煤层为例,从现有采煤方法和水文地质条件出发,研究奥灰含水层的富水性能和底板隔水层的分布规律,并以突水系数等值线图评估安全开采可行性,选择煤矸石充填开采并进行成本分析。Taking Tianyu coal mine No. 9 coal seam in Inner Mongolia Wuhai city as an example, it is from current mining method and hydrogeological condition to study water rich property in Ordovician limestone aquifer and distribution law of water resisting floor. Safety mining feasibility study is conducted by groundwater bursting coefficient contour map. Gangue backfill system is conducted with cost analysis.
