液压凿岩机是七十年代发展起来的新设备,被人们称为“凿岩机的新一代”。它与风动凿岩机相比,具有高钻速、低能耗、低污染和容易实现自动化等优点。近年来,在国外矿山和各种岩石工程中得到了迅速的发展,已有取代风动凿岩机的趋势。国内也已取得了可喜的进展,至今年5月止已鉴定了9个型号,在冲击部效率上本机是最高的。 本机是广西壮族自治区于1976年3月为了解决采矿中深孔凿岩问题,下达的科研任
Hydraulic rock drill was developed in the seventies new equipment, known as “a new generation of rock drills.” Compared with the pneumatic rock drill, it has the advantages of high penetration rate, low energy consumption, low pollution and easy automation. In recent years, rapid development has been made in foreign mines and various rock projects, and the trend of replacing wind-driven rock drills has been achieved. There have also been encouraging developments in China. Up to May this year, nine models have been identified and the unit is the highest on impact department efficiency. This machine is Guangxi Zhuang Autonomous Region in March 1976 in order to solve the problem of deep-hole drilling in mining, issued by any of the research
