摘要
通过对某大型露天矿山矿用电动轮汽车使用的考察和调研,结合国内矿山电动轮汽车实际使用期限,运用现场数据统计分析,对电动轮汽车经济寿命影响因素进行深入分析,估算出国内矿用电动轮汽车的最佳经济寿命为11.38年。
Through inspecting and investing the usage of mining electric trucks in some large-scale surface mines and combining with the actual life of mining electric trucks in domestic mines, the economic life influencing factors of mining electric trucks are analy：ed by using statistical analysis of .field data. The best economic life of domestic mining electric trucks is estimated at 11.38 years.
