| 摘 要： | 通过对北京矿务局木城涧矿十槽煤不具备常规复采条件底煤复采的相似材料模拟试验研究，证明了回采上分层时顶板冒落情况和矿压显现规律，初步探明了留与不留煤皮假顶情况下，回采下分层时顶板岩层二次失稳情况和矿压显现规律，为类似条件底煤复采制定合理的复采方案、安全技术措施等提供重要的依据和指导作用。

| Abstract: | By using simulating experimental means of similar material, this paper indicates the investigation of extracting sublayer coal in Muchengian colliery under abnormal condition and mine pressure showing laws and testifies caving conditions when extracting toplayer coal ,at the same time , this paper studies top roof rock seam destabilization again and mine pressure showing law when extract sublayer coal under artificial coal seam of top coal remained and top mined,the resuits identically on-the-spot extracting laws,and it provides important lasis for rational and safety plan for similar conditions of sublayer coal mined. |
