摘　　要：选取合理的锚杆支护参数,不仅可以满足安全生产需求,还可以节约资金,提升支护效率。根据某矿91-101回风巷在采取两种支护参数前后的变形及掘进速度和支护成本方面的分析,选择了更为合理的支护参数。实践证明,在类似条件下,该支护参数支护效果较好。Selecting reasonable bolt supporting parameters can not only meet the safety requirements,but also save money and improve efficiency.Based on the analysis of deformation,excavation speed and supporting cost of 91-101 return air roadway before and after adopting two supporting parameters,this paper selected more reasonable supporting parameters.Practice has proved that the supporting parameters are desirable under similar conditions.
