摘　　要：在深凹露天采场掘沟工程中,因为丰富的地下水的影响,如何提高掘沟穿孔成功率成为许多矿山生产过程中的难题。本钢矿业公司专业人员进行了这方面有益的探索,寻求到了在地下水、地表水丰富情况下,提高掘沟成孔率的有效方法,使用护孔套筒形成完整孔口,成功解决了这一技术难题。对其它深凹露天矿山和类似工程中有一定的参考价值。The abundant groundwater always has some effect on the deep sunken open pit ditch engineering. So how to improve the success rate of trenching perforation has become a usual problem which is difficult to deal with in the process of production in many mines. Benxi Steel mining company professionals have carried on the beneficial exploration on this subject. In this paper, we＇d like to introduce the solution we found, that under the condition of abundant ground water, surface water, the effective method to improve the success rate of trenching perforation. That using protection sleeve hole formed complete orifice successfully solved the technical difficult problem. For other deep open pit mines and similar projects have some reference value.
