摘　　要：以阳煤五矿为例,采用矿井瞬变电磁法详细探查了工作面底板隐伏地质构造及富水异常区,并利用巷道控制点底板标高和钻孔数据计算突水系数,进而采用矿井瞬变电磁探测成果与突水系数相结合的方法,对地质构造复杂段的富水情况进行综合评价,确保了工作面底板带压区的安全回采。Yangquan coal industry No.5 coal mine,for example, the mine transient electromagnetic metho d was used to detect the concealed geological structure and water anomaly area of working face floor, and water bursting coefficient was calculated by using the control points floor level of the roadway and drillings data,then the method of mine transient electromagnetic exploration results combined with water bursting coefficient are adopted to evaluate comprehensively of water situation in the complex section of the geological structure, and has ensured safety mining in working face floor with pressure zone.

关 键 词：突水系数 带压开采 安全评价
