摘要
从巷道围岩所处具体层位、岩性和巷道压力显形特点等方面入手,选择巷道支护形式,并通过巷道的实验,找出适合朱仙庄矿高地应力软岩巷道的合理支护参数,解决部分软岩巷道支护问题,缓解软岩支护矛盾,以达到永久支护效果。
From the concrete roadway layer, rock lithology and characteristics of roadway pressure chooses the form of roadway support, and through the tunnel experiment to identify reasonable support parameters of high stress soft rock tunnel of Zhuxianzhuang Coal Mine, solve some problems of soft rock roadway support, in order to achieve permanent support results.
