液压凿岩机和钻车从七十年代开始用于采矿作业时,它主要用在平巷掘进的水平凿孔上。在回采中采用液压凿岩钻车主要限于房柱开采法中,因为用这种采矿方法时,水平凿孔和爆破方法基本上与平巷掘进和隧道掘进时相同。液压凿岩钻车公认的优点是凿速快,工作环境得到改善,噪音低而且能见度较好。在液压凿岩钻车在水平凿孔上的应用迅速得到普及时,大直径潜孔钻机(通常是钻竖直或接近竖直的下向孔)也开始在回采急倾斜的矿体中得到日益广泛的应用,回采方
Hydraulic rock drills and rigs have been used mainly for horizontal boreholes in drifting tunnels since they were used in mining operations in the 1970s. The use of hydraulic rock drilling rigs in the recovery is mainly limited to the column and pillar mining method because the horizontal drilling and blasting methods are basically the same as for the tunneling and tunneling with this mining method. The recognized advantages of hydraulic rock drilling rigs are fast chipping speed, improved working conditions, low noise and good visibility. Large-diameter downhole drilling rigs (usually uprights or near vertical downwards holes) are also beginning to gain traction in steeply dipping orebodies as hydraulic rock drill rigs are rapidly gaining popularity in horizontal boreholes A wide range of applications, mining side
