摘要
为了确定锚杆支护在巷道中起到的加固作用,通过对山西省长治经坊煤业有限公司3-6011辅助运输巷现场调研、井下钻孔窥视,并形成窥视孔柱状图,对顶板地质情况进行分析,并对围岩地质力学评价,最终确定3-6012辅助运输巷锚杆支护方案及支护参数。
In order to determine strengthening function of anchor bolt support in roadway, peephole column was formed to analyze roof geological condition and evaluate geomechanics of surrounding rock through field investigation and underground borehole peering of 3 - 6011 auxiliary haulage lane, which finally determined anchor bolt support scheme and support parameters of 3 - 6011 anxiliary haulage roadway.
