液压凿岩设备问世已经十年了。迄今已用于从北极到热带的各井下和地面的矿山工程作业。加拿大的Inco公司于1975年第一次在采矿作业中使用液压凿岩设备,从1976年以来,加拿大已售出了50多台液压钻车。六十年代中期,出现了装运机和风动钻车,但设备规格不能使所有矿山都采用这种先进设备。当液压凿岩设备上市时,其尺寸与风动相似,依然没考虑更小矿山的需要。随着越来越多的液压设备投入使用,厂商和矿业主明显地感到,用双臂液压钻车来代替双臂风动钻车不是太有必要,因为在某些情况下,如独头巷道掘进,高生产率的双臂液压凿岩设备便不能充分发挥其潜力,所以,开始出
Hydraulic rock drilling equipment has been around for ten years. So far it has been used for mine engineering work on all boreholes and on the ground from the Arctic to the tropics. Inco of Canada used its hydraulic drilling equipment for mining operations for the first time in 1975, and since 1976, more than 50 hydraulic rigs have been sold in Canada. In the mid-1960s, there was a loader and a pneumatic drill, but the specification of the equipment did not make it possible for all mines to use this advanced equipment. When hydraulic rock drilling equipment is on the market, its dimensions are similar to those of aeroengines and still do not take into account the needs of smaller mines. As more and more hydraulics come into operation, it is clear to manufacturers and mine owners that it is not necessary to replace two-arm hydraulic drilling with two-arm hydraulic drilling because in some cases, Driven, high-productivity, dual-arm hydraulic rock drilling equipment can not fully exploit its potential, so start out
