摘要
通过水文地质和工程地质条件分析、相似材料模拟和数值模拟认为淮北海孜煤矿的顶板水害为次生离层水包破裂所致,钻探和光学成像证实了分析和实验结果。针对灾害原因,采取了采动疏干的防治水方法,取得了满意的效果,确保了类似条件工作面开采的安全。
The water hazard was deduced as the cause of water cell breaking wllich was caused by over burden strata separation during mining activities according to hydrogeological and geotechnical analyses, physical analogue and numerical simulation. Drilling and borehole scanning verified the above results. To control the water hazards, the responding draining measure was taken and the tests were successful. The achievements were applied to the working faces with the similar hydrogeological condition to guarantee mining safe.
