在我国,矿山为了维持其生产,必须付出相当大的机械维修费用。据了解,维修费用约占矿石生产成本的15～20%。可见,它是矿山经济的重要组成部份,应予以重视。一、矿山机械维修费用的构成矿山机械经过修复后投入生产,可创造经济价值,所以其维修是否合理,最终是用经济指标来反映的。以湘潭锰矿红旗矿区为例,1982年,生产矿石15.5万吨,拥有设备总重932.8吨,总装机容量约7000千瓦,全年总维修费用103.95万元,万吨矿石维修费用为6.7万元,其构成如表1。
In our country, mines have to pay considerable mechanical maintenance costs in order to maintain their production. It is understood that the maintenance costs account for about 15 to 20% of ore production costs. Can be seen, it is an important part of the mine economy, should be taken seriously. First, the composition of mine machinery maintenance costs Mine machinery after repair put into production, can create economic value, so the maintenance is reasonable, and ultimately is reflected in economic indicators. Take Xiangtan Manganese Mine Hongqi Mining Area as an example. In 1982, it produced 155,000 tons of ore and owns 932.8 tons of equipment with a total installed capacity of 7,000 kilowatts. The total maintenance cost for the year was 1,093,900 yuan and the maintenance cost for 10,000 tons of ore was 67,000 yuan, Its composition is shown in Table 1.
