巷道锚杆索支护方式优化设计

Optimization Design of Bolt-cable Anchor Supporting of Roadway

以盖州市某煤矿为研究对象,运用数值计算方法对5种支护方式进行了深入研究,得到结论:(1)在设计锚索时,用锚索置换拟放置的锚杆,这不仅可以降低支护成本还能得到更好的支护效果;(2)在设计支护方式时,如果不用钢筋梯对锚索进行连接,应将锚索和锚杆同排布置。

Take a mine in Gaizhou as the research object, study the supporting effect of 5 types of supporting methods by using numerical calculation method, could conclude as follows：（1）in design of anchor cable, it can not only reduce support costs but also can have a better supporting effect by using the anchor cable to replace bolt;（2）when designing supporting method, if the anchor cables are not connected by steel ladder, the anchor cable and blot should be in the same row.
