炮孔钻凿设备是矿山采掘、交通隧道、水利涵洞及地下工程中的主要装备,对提高工作效率,改善工作环境,提高经济效益和社会效益起有显著作用。特别是钻凿设备由气动到液压的更新换代,以及孔径和孔深的增大,促使工矿企业获得很大的效益增值。近十几年来,产量增加60%~70%;劳动生产率提高了2.5~3倍。随着工业技术的飞速发展,各国对液压钻凿设备的创新发展已更加关注。
Drilling hole drilling equipment is the main equipment in mining excavation, traffic tunnels, water conservancy culverts and underground engineering, and plays a significant role in improving work efficiency, improving working environment and raising economic and social benefits. In particular, drilling equipment from the pneumatic to hydraulic replacement, as well as the increase in aperture and hole depth, prompting industrial and mining enterprises to obtain a great benefit value. In the past ten years, the output has increased by 60% ~ 70%; the labor productivity has been increased by 2.5 ~ 3 times. With the rapid development of industrial technology, all countries have paid more attention to the innovation and development of hydraulic drilling equipment.
