摘要
兰兴煤矿正处于开拓阶段,巷道顶板易破碎,巷道锚杆支护缺乏合理的支护参数,通过对2#煤层顶板岩层强度特征进行分析,依据其顶板强度特征,选择适合其巷道顶板及两帮岩性的锚杆支护理论,详细的分析了其运输大巷锚杆支护参数确定过程及其应用效果,对其他巷道支护参数具有一定的指导意义。
Being in the pioneering stage, roadway roof is easy to break and rock bolting lacks of reasonable sup- port parameters in Lanxing Colliery. By analyzing characteristics of roof strata strength at No. 2 seam, bolt sup- port theory suitable for roadway roof and lithology of both sides has been chosen based on the characteristics of roof strength, the paper has made detailed analysis on the courses of bolt .support parameter definition of main haulageway and its application effect, which has a certain significance for other roadway support parameters.
