摘要
根据巷道围岩的变化,按照不同锚杆、锚索,钢带、钢网支护时的参数设计、施工及措施要求,确保复合顶板综采切眼支护的可靠性,实现了安全生产,取得了理想的经济效益,对类似条件下掘进工作面支护设计和施工有较高的借鉴价值。
According to the variety of tunnel surrounding rocks, and the demand of parameters designing, constmction of different bolt wihe mesh, steel belt and net, assure of reliability of support of compound roof, so as to realize safety prodution, get ideal economic profit. It has high valuable reference for the sinilar driving, support and construction.
