最近,在金属矿山和石灰石矿,为了推广无轨采矿并防止振动危害,正着眼于凿岩机的钻车化以及铲运机的普及。作为这些设备的驱动装置,柴油机的使用日益增多。特别是由于运输距离、运行速度的增大,使设备具有逐渐向大型化发展的趋势。到1974年6月为止,矿山使用柴油机驱动的设备已达 Recently, at metal mines and limestone mines, drilling rigs for drilling rigs and popularization of scrapers have been focused on the promotion of trackless mining and the prevention of vibration hazards. Diesel engines are increasingly used as a drive for these devices. Especially due to the transport distance, operating speed increases, so that the equipment has the tendency to gradually large-scale development. By June 1974, the use of diesel-powered equipment at the mine had been reached
