水泥卷锚杆支护法快速掘进巷道的实践

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。

The practice of quick tunneling based on concrete scroll rockbolt supporing

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.
