摘要
分析了倾斜长壁综采放顶煤采场顶板受力与破坏情况，用材料力学理论推导出了基本顶岩层初次垮落和周期垮落步距的计算公式，并简单分析了仰、俯斜开采采场矿压特点。
Studied roof stress and destroy state of stope of longwall caving method along the dip in the fully mechanized mining,and induced calculating formula of first and periodic caving pace of main roof strata in accordance with material mechanics theory.At the same time,analyzed simply mine pressure feature of stope of up dip and down dip mining.
