针对铺龙湾煤矿4102综放工作面切眼实况,依据锚杆锚索支护原理,制定了合理的巷道支护方案及参数,并对实施效果进行检测分析,证实“锚杆+锚索+金属网”联合支护方式在大断面综采切眼软质(不坚固)围岩巷道一次成巷中的应用是可行的。
According to the actual situation of cut face of 4102 fully mechanized coal caving face in Paolongwan Coal Mine, according to the principle of bolt and anchor support, a reasonable roadway support plan and parameters were established and the effect of test was analyzed. It was verified that “anchor + anchor + Metal mesh ”joint support method in a large section of fully mechanized cut eye soft (not strong) surrounding rock roadway into a lane is feasible.
