摘要
通过对祁东煤矿南部采区钻孔资料的收集统计,分析了南部采区松散层底部四含水的富水性特征,并分别考虑当四含水作为间接充水和直接充水含水层时,对南部采区61煤层6161工作面的四含充水性影响进行了分析,为工作面的防水煤(岩)柱设计提供了参考。
By collecting statistics the drilling data for southern part of the Qidong coal mine, the fourth aquifer water rich characteristics for bottom of loose layer in southern mining area are analyzed, and by considered separately as the indirect water filling and the direct water filling aquifer, the fourth aquifer water filling property for 6161 working face in southern mining area are analyzed, which provides reference for design of waterproof coal （rock） pillar of working face.
