实践证明,要露天矿保持高效而经济的正常生产,关键问题之一是把露天矿的采、运、排设备及其辅助设备使用好、维修好,管理好。但是,在过去某些矿山的具体设计管理工作中,往往存在忽视维修设施的设、置忽视司乘人员培训、忽视机电设备维修的偏向。霍林河露天煤矿引进的中型设备运转状况不好,就是一个值得深思的例子。据1982～1984年的统计,该矿RH—75液压挖掘机平均年作业小时数仅达1992小时,平均台年生产能力只达94万立方米,75—B自卸汽车平均年作业小时1810小时,平均台年生产能力为14万米~3,均比国内设计规定的指标低,更低于美国同类设备的生产能力。例如,美国、西德为我国准格尔、元宝山煤矿所作的
Practice has proved that to open-air mines to maintain efficient and economical normal production, one of the key issues is to open-pit mines, transportation equipment and auxiliary equipment, good use, well-maintained and well managed. However, in the past, some mine design and management work often overlooked maintenance facilities, ignoring division training and ignoring mechanical and electrical equipment maintenance bias. The medium-sized equipment introduced from Huolinhe open-pit coal mine is in poor working condition, which is a worthwhile example. According to the statistics from 1982 to 1984, the average annual operating hours of the RH-75 hydraulic excavator in the mine only reached 1992 hours, with an average annual production capacity of only 940,000 cubic meters. The average annual operating hours of the 75-B dump trucks were 1,810 hours , The average annual production capacity of 140,000 meters ~ 3, lower than the indicators of domestic design requirements, lower than the production capacity of similar equipment in the United States. For example, the United States, West Germany for China’s Zhungeer, Yuanbaoshan coal mine made
