大倾角煤层锚梁网支护技术应用分析

Application Analysis of Roof Bolting with Bar and Wire Mesh Technology in Coal Seam with Large Inclined Angle

在分析潘北矿11118工作面运输巷锚梁网原支护设计的基础上,结合井下支护条件和实际支护效果,对原有设计巷道断面及支护参数进行补充修改,使得大倾角煤巷锚杆方式在支护结构上更加合理,生产过程更具可操作性,从而保证了巷道的支护效果及施工质量,节约了支护成本的投入。

By analyzing former supporting design of roof bolting with bar and wire mesh on 11118 working face of Panbei Coal Mine,the old parameters of designed roadway section and supporting were modified and optimized combined with the actual downhole conditions and on-site supporting effects,which made supporting structure of coal roadway in coal seam with large inclined angle more reasonable,process more operational,thus ensured the effect of roadway supporting and construction quality,and saved input of supporting costs.
