液压凿岩机是七十年代发展起来的一种新型高效率凿岩设备。它的出现,在凿岩机的动力和效率方面是一次重大的变革。世界许多国家竞相研制,发展很快。据不完全统计,目前已在九个国家、近二十家公司研制出近五十种样机,市场上正式出售的产品已达十余种之多。我们的液压凿岩机研制工作是于1973年开始的,协作单位有:长沙矿冶研究所、株洲矿山工具厂、天水风动工具研究所、湘东钨矿和木城涧煤矿。研制工作在经历了设计、试制、厂内调试和中间试验等阶段之后,于1976年分别在湖南湘东钨矿和北京木城涧煤
Hydraulic rock drill is developed in the seventies a new type of high efficiency rock drilling equipment. Its emergence was a major change in the power and efficiency of rock drills. Many countries in the world compete to develop and develop rapidly. According to incomplete statistics, nearly 50 prototypes have been developed in nearly 20 countries in nine countries and the number of products officially on the market has reached more than 10. Our hydraulic rock drill development work began in 1973, the collaborators are: Changsha Institute of Mining and Metallurgy, Zhuzhou Mining Tools Factory, Tianshui Institute of wind tools, tungsten ore and Cheung Shing coal mine. Research and development work experience in the design, trial production, the factory commissioning and intermediate tests and other stages, respectively, in 1976, Hunan Xiangdong tungsten ore and Beijing Wood City Stream coal
