Abstract: The drilling work can be done with the compressed-air driven percussion drill，the hydraulic pressure rotation drill and the multi-purpose drill at different geological conditions. The drilling conditions of deep holes for soft surrounding rock are obtained. The important technical support for pre-drilling and pre-reinforcement at soft surrounding rock is provided. 分别通过对风动冲击钻机、液压回转钻机、多功能钻机在不同地质条件下的钻凿作业进行分析，得出在软弱围岩成功实现深孔钻凿穿越的条件，为软弱围岩的超前钻探与预加固提供重要技术支持。
