【摘要】 以山西某矿6101综采工作面为背景对软弱顶板下综采工作面的矿压显现规律进行了研究,并根据矿压显现特征调整了回采巷道超前支护距离。研究结果为保证矿井安全高效生产提供有利的支撑,也为其他矿井类似条件下回采工作的开展提供了一定的借鉴。更多还原

【Abstract】 Based on the 6101 fully mechanized mining face of a mine in Shanxi Province, the law of strata pressure appearance of fully mechanized mining face under weak roof is studied, and the advance support distance of mining roadway is adjusted according to the characteristics of strata pressure appearance. The research results provide favorable support for ensuring the safe and efficient production of the mine, and also provide a certain reference for the development of mining work under similar conditions in other mines.更多还原
