摘　　要：目前对于水体下长壁开采的理论和安全评价机制已近成熟,但对于崩落法采煤上覆岩层的破坏规律还缺乏研究,文章以山东枣庄矿区3#煤中厚天然焦开采试采区为背景,通过理论分析和数值模拟方法,研究了大面积厚层天然焦崩落法开采顶板突然破坏导致的覆岩破坏特征和发育高度,为水体下崩落法采煤提供了理论依据和安全保障。At present, the longwall mining theory under the water body and the safety evaluation mechanism are becoming in mature. There is a less study on the failure law of the overburden strata above the coal mining with the blasting and caving method. Taking the thick mineral coke mining trial face in No. 3 seam of a mine in Shandong as the background, with the theoretical analysis and numerical simulation method, the overburden strata failure features and development height to cause the mining roof sudden failure during the blasting and caving method of thick mineral coke in large area were studied. And the study could provide the theoretical basis and safety protection to the mining with the blasting and caving method under the water body.
