摘　　要：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。For the open-off cut in 4102 fully-mechanized working face of Pulongwan mine,based on bolt-anchor supporting theory,a roadway supporting plan with rational parameters was made.Effect testing and analysis proved that the bolt-anchor-net combined support was feasible in large section open-off cut in soft(loose) surrounding rock roadways.
