| 摘 要： | 介绍了模拟综放开采覆岩及顶煤的移动规律。正常放煤过程．顶煤呈现煤壁内受压裂．支架上方破碎．支架放煤口上方成散体的规律．这一规律随工作面推进．顺的序周而复始的进行。支架承受的是上方煤体和折断部分直接顶的载荷。

| Abstract: | This paper introduces the moving law of ovcrlying strata and top-coal in full-mechanizedbrawing coal model test.This law is that pressure and cracks appear in top-coal, breaking uppersupport and loosing on releasing chute of support during general drawing coal period.This law appears periodically following face. The outport bears the load of top-coal and breahs immediate roof. |
