硬厚片麻岩下综放采煤覆岩破坏规律初探
ANALYZING THE REASON OF WATER BURST IN HORIZONTAL ROADWAY OF NO.1 HUANGLING COAL MINE
【摘要】 新集煤矿13 煤处于厚层、坚硬推覆体片麻岩下综放开采,通过对覆岩破坏的应力法预测和地面施工钻孔探测,初步掌握了坚硬片麻岩的采后破坏规律,为坚硬顶板下安全开采和片麻岩下提高开采上限提供了依据。
【Abstract】 Analyze the reason of the water burst from three aspects,i.e.,hydrology and engineering geology,investigating and inspecting of the source of water burst,and physical exploration.
