摘　　要：以金凤煤矿011804工作面采空区为例,根据该采空区积水特征,在011804工作面下区段的011806回风巷建立排水系统,布置钻场,开展钻探作业,并对疏放水量进行动态观测与统计,计算得出了采空区积水充水系数,摸清了采空区积水分布规律,为金凤煤矿其它工作面采空区积水量计算及积水分布特征分析提供了依据。Taking Jinfeng Coal Mine 011804 working face goaf as an example, according to the characteristics of goaf water, drainage system is built in the 011806 wind alley of 011804 working face section, drilling field is arranged to carry out drilling operations, and dynamic observation and statistics of drainage water are made. The water filling coefficient of goaf is calculated, the distribution law of goaf water is found out to provide the basis for calculation of ponding volume and analysis of water distribution characteristics of other mining face in Jinfeng Coal Mine.
