一、前言风动凿岩机已有100年的历史，几经改进和不断完善，虽有很大提高，但最大的缺点就是能量利用率低，凿岩时，由于排气含有大量油雾，恶化了作业环境和视野，并有很大的噪音。1970年法国蒙塔贝特公司试制成功第一台液压凿岩机后，受到各国极大的注意。液压凿岩机一出现，就显示了它的优越性，很快得到了推广使用。据报道国外从1974年开工的大型隧道工程，几乎均采用了液压凿岩机，也都取得了很好效果。在这些凿岩机中，欧洲一般使用法国蒙塔贝特公司和瑞典阿特拉斯·科普柯公司的产品，在美国则主要使用英格索尔一兰德公司的产品。
I. INTRODUCTION The pneumatic rock drill has a history of 100 years. Although it has been greatly improved, it has been greatly improved. However, the biggest drawback is the low energy utilization rate. During rock drilling, the exhaust gas contains a lot of oil mist, which deteriorates the operation. Environment and vision, and there is a lot of noise. After the successful trial production of the first hydraulic rock drill by the French company Montabet in 1970, it received great attention from various countries. As soon as the hydraulic rock drill appeared, it showed its superiority and was quickly promoted. It has been reported that almost all foreign large-scale tunnel projects started in 1974 have adopted hydraulic rock drills and have also achieved good results. Among these rock drills, Europe generally uses the products of Montabet, France and Atlas Copco, Sweden. In the United States, it mainly uses Ingersoll-Rand products.
