法国奥德省萨尔西涅金矿,最近在露天开采中,使用一个钻程钻孔12米的液压钻车。这种钻车由蒙塔贝公司设计和制造,装在Cat235型挖掘机的底盘上。有一个钻臂,其伸缩长度为1.5米。钻臂上安装有液压马达滑架和GCT19型链条,可安装长6.1米、直径45毫米钻杆2根(螺纹连接,无连接器)。滑架可回转90°,以使司机室内钻孔工有良好的视线。使用第三代HC120 ER型液压凿岩机,在萨尔西涅金矿钻凿一个直径89毫米、深12米的炮孔,约需6分钟。钻车上有一台压风机供应湿风清扫炮
The Salginie gold mine in Aude, France, recently used open pit drilling with a 12m hydraulic drilling rig. Designed and manufactured by Montauban, this rig is mounted on the chassis of a Cat235 excavator. There is a boom, the telescopic length of 1.5 meters. The boom is equipped with a hydraulic motor carriage and a GCT19-type chain for the installation of two 6.1-meter-long, 45-mm diameter drill rods (threaded, without connector). The carriage swivels 90 ° so that the driver’s bore driller has a good view. Using a third-generation HC120 ER hydraulic rock drill, a hole 89 mm in diameter and 12 meters deep was drilled at the Salzgini mine in about 6 minutes. There is a blower on the car that supplies wet wind sweeper
