摘要
为了确定某矿采区专用回风巷围岩合理的支护体系,对矿井采区专用回风巷围岩具体的地质情况和巷道所处不利条件进行了分析,确定了在不同情况下的巷道支护形式和参数。工程实践表明,设计的锚杆、锚索支护方案在采区专用回风巷支护效果较好,能保证巷道围岩的稳定性。
In order to determine a reasonable supporting system for the surrounding rock of a special return airway in a mining area, the specific geological conditions of the surrounding rock and the unfavorable conditions in the roadway were analyzed, and the form and parameters of the roadway supporting under different conditions were determined. The engineering practice shows that the bolting and anchor supporting scheme is effective in the special return airway of the mining area, and it can ensure the stability of the surrounding rock of the roadway.
