| 摘 要： | 对悬移支架普采工作面进行了观测,实测了支架活柱下缩量、工作面顶板移近量、顶板的来压强度以及巷道变形破坏参数,总结了该矿悬移支架普采工作面的矿压显现规律。观测表明该工作面老顶来压强度不高,所选悬移支架能平衡顶板压力,满足工作面正常开采时对支护阻力的要求。针对目前顶板的支护状况和顶板灾变危险,提出了提高支架初撑力等改善措施,研究成果对指导该矿区中小型矿井普采工作面具有重要意义。

| Abstract: | On the observation of movable support machine mining working face,the support sink,the main roof sink and the main roof intension and entry distort and entry destroy parameter are analyzed.The weighting law in movable support machine mining working face is gained.The observation indicates the main roof strength is small and the support can balance the load of the rock and can meet the requirement of normal mining.In view of the support and disaster situation,the support measure is put forward to improve the... |
