桁架锚索在7518切眼支护中的应用

Application of the Braced Girder and Anchored Cable in the 7518 Open - Off Cutting Timbering

以五阳煤矿7518综放工作面开切眼锚杆锚索联合支护为例,介绍了桁架锚索的技术特点及施工工艺,说明了桁架锚索对复杂、困难条件下的巷道支护所起的补强作用,为大断面综放工作面开切眼锚杆支护技术的推广应用,提供了经验参考。

The article introduces the technical characteristic and executive technology of the braced girder and anchored cable, taking the example of braced girder and anchored cable combined support in the open - off cutting timbering in the 7518 working face in the Wuyang coal mine. It clarifies the strengthening function of the braced girder and anchored cable in the complex and difficult condi- tions of the drift timbering. It provides the experiential reference to the generalized application of the technology of braced girder and anchored cable in the open - off cutting in the big section working face.
