摘要
针对寺河2号井97盘区支护过剩、成本高的特点,对现有支护方案进行优化,通过理论计算,数值模拟分析,采用耦合让均压支护设计理念,引入弹塑形支护设计准则,确定了九七盘区大巷的新支护系统的基本参数,达到了巷道安全、经济、快速的掘进目标,对于九七采区的安全、经济开采具有重要的现实意义,为该矿井类似条件下巷道支护设计提供参考和依据。
According to sihe No.2 97 panel bolting supporting excess, the characteristics of the high cost, by means of theoretical calculation and numerical simulation, the design concept of coupling pressure equalization support is introduced. The design parameters of the new support system of the 97 panel roadway were determined, which reached the goal of safe, economic and fast excavation of the roadway, which was very important for the safety and economic exploitation of the 97 mining area Practical significance. And it provides the reference and the basis for the mine roadway support design under the similar condition.
