一、电动铲运机的由来与发展以柴油铲运机为主的内燃无轨采掘设备的出现和不断完善,引起了地下采矿方法和开拓方式的变革,显著地提高了劳动生产率.西方各国地下金属矿山无轨采矿的比重已达三分之二,苏联也达四分之一.七十年代以来,国外新建地下矿山基本上都是按无轨采矿设计的.可以说,六十年代后半期以来,国外地下矿山经历了一个以采用内燃无轨自行设备为中心的、由有轨向无轨过渡的技术改造阶段.
I. The Origin and Development of Electric Scrapers The appearance and continuous improvement of the internal combustion trackless mining equipment mainly driven by diesel scrapers has led to the change of the underground mining methods and development methods and markedly enhanced the labor productivity. The proportion of mine-free track mining has reached two-thirds, the Soviet Union also reached a quarter.Since the seventies, foreign new underground mines are basically designed according to trackless mining.Can say, since the second half of the sixties, foreign Underground mines have undergone a phase of technological transformation from rail-to-railless transition centering on self-contained diesel-rail-based equipment.
