摘要
分析并优化夹河矿2442运输巷支护参数,在实践中对构造应力区域施工工艺进行改造,从而保证了构造应力区域的有效支护。
Based on result of analysis,optimization is made of the parameters of the bolting plus wire mesh supporting system used in the 2442 haulage roadway of Jiahe Coal Mine.In the practical application of such a system in the region subjected to tectonic stress,the roadway development process is modified,with an aim to ensuring the effectiveness of the supporting system in such a geologically unfavorable region.
