摘　　要：对于不稳固岩石中巷道的掘进,矿山一般采用木支护普通掘进法,成本高、效率低、安全性差。文中介绍了一种用水泥卷锚杆支护的掘进新工艺,不但工作安全可靠,降低了掘进成本,而且大大提高了掘进速度。For tunneling in the incompetent rock,most mining companies adopt wooden supporting system,the cost of which is high,the efficiency is low and the security is less satisfactory. A new method is presented,namely concrete scroll rockbolt supporing . Not only does it improve the security of working and reduce mining costs,but also it accelerates tunneling speed.
