| 摘 要： | 露天矿采场边坡、交通路堑边坡、水电工业场地边坡等岩石开挖工程均采用钻眼爆破，目的是破碎岩石。通常爆破力并不停止在破碎线，而是继续深入到帮壁的岩石中，这就弱化了岩石，有时甚至破坏了正好维持稳定性所需要的强度。众所周知，一般爆破后岩石后冲较大，往往造成与爆源直接邻近的边壁损坏，如台阶(梯段)顶部的龟裂，表层岩石的松动，

| Abstract: | The paper introduces rock drilling in slope level with KQX120 Cutting DTH drill about itsprinciple, method, manufacture of drilling tool and effect. Contrasting with retrofittedgeological probe drilling facilities, the result shows that the construction cost is lower andeffect is better with KQX120 drill |
