液压凿岩——前十年和后十年即计算机、自动化和许多别的发展。液压凿岩设备首次成为气动凿岩机以外可以采用的一种重要设备只不过是十年前的事。今天以及今后一段时间内液压凿岩机是进行新的地下开拓首先选用的设备。现在已有许多改进,旨在提高设备的可靠性以及提高凿岩机、液压系统和安设凿岩机的液压支臂的工作效率。芬兰和瑞典的主要制造厂近来已采用新的一代液压凿岩机。别的国家的其他制造厂商在今年也在现场开始使用新型液压凿岩机。凿岩操作自动化是最大限度地发挥液压凿岩机的非凡凿岩能力的途径,目
Hydraulic rock drilling - the first decade and the decade after computer, automation and many other developments. For the first time, hydraulic rock drilling equipment can become an important equipment other than pneumatic rock drilling machine is only a matter of a decade ago. Today and for some time to come, hydraulic rock drills are the first choice of equipment for a new underground development. Many improvements have been made to improve the reliability of the equipment and to improve the working efficiency of rock jacks, hydraulics and hydraulic arms for setting up rock drills. The major manufacturing plants in Finland and Sweden have recently adopted a new generation of hydraulic rock drills. Other manufacturers in other countries are also starting to use the new hydraulic rock drill this year. Drilling operations automation is to maximize the hydraulic drilling machine extraordinary drilling capacity of the way, head
