摘要
松软岩层中的井下巷道支护是目前矿山建设中的一个主要难点．针对车集煤矿的具体条件，对井下巷道的破坏形式及破坏机理进行了分析，在此基础上，提出了锚注法修复加固方案，并阐述了锚注法的支护机理及支护参数．实践表明，应用效果显著．
The support in soft rock drifts is the main difficult point of mine construction. In view of concrete conditions in Juji coal mine, the form and the mechanism of damage in soft rock drifts are analyzed. Based on the analysis results, a reinforcement plan of rock bolting and grouting is drawn up. The support mechanism and the parameters of rock bolting and grouting method are also expounded. It is proved by practice that the applied effects are remarkable.
