摘要
分析了煤层开采上覆岩层的破坏规律,提出在地面通过钻孔向采空空间和采空区灌注高水材料充填体,使高水材料充满冒落裂隙带和垮落带裂隙以控制或消除地表沉降。
Analyzes the destruction law of overlying strata in coal mining, and puts forward that filling ultra-high water material in to the mined-out space and gob by drilling in the ground to fill the caving fractured zone and fissures in caving zone with high water material can control and eliminate surface subsidence.
