| 摘 要： | 应用理论分析、数值模拟等方法,对错层位工作面与传统放顶煤工作面上覆岩层的结构进行分析,得出错层位巷道布置下工作面新的上覆岩层的结构,即L形垮落方式和基本顶呈悬壁梁状的破断传递;得出错层位工作面上覆岩层易垮落,较传统放顶煤工作面上方易垮落区域面积要大,而且高度约有100 m;由于接续工作面的连续推进,使得接续工作面上覆岩层的垮落与首采工作面垮落的岩层连与一个更大的梯形区域,而且梯形区域的高度有120 m左右.

| Abstract: | With the theoretical analysis, numerical simulation and other methods, the paper analyzed the strata above the coal mining face in dislocated seam and conventional top coal caving mining face. The analysis results showed that the above new strata structure of the coal mining face in the dislocated seam were in L falling type and the basic roof was in a suspended beam for breaking transmission. The results showed that the strata above the coal mining face in dislocated seam were easy to fall down and the fal... |
