摘要
以牛马司煤业公司水井头矿-300东大巷的软岩支护问题为研究对象,在测试软岩矿物成分的基础上,分析了膨胀型软岩巷道变形的机理和围岩控制方法,提出了锚网喷注的联合支护方案。工业试验表明,该技术取得了良好的支护效果和经济效益,对同类软岩巷道具有一定的借鉴作用。
Taking the problem of supporting the soft rock haulage tunnel at the southern -300 m level in Shuijingtou Coal Mine of Niumasi Coal Industry Company in China as the object of study, mineral components of the soft rock were tested, deformation mechanisms of the soft rock roadway were analyzed, and ways for strata control were proposed. A supporting method with combined use of shorcrete-boh, steel wire net, steel strip and grouting was put forward. The in- dustrial experimentation shows that the support technology has resulting in a good supporting effect, and great economic profit, providing a reference for the support of same sort of soft rock roadways.
