李国政
云南磷化集团有限公司昆阳磷矿分公司云南省昆明市 650600
摘要：昆阳磷矿在用 40 台运输车辆均进入故障损耗期，运转率降下降、故障率升高，运行成本逐年增加。其中
小松 HD325-6 自卸车于 2007 年投入使用，已累计平均运行 33000h；20 台卡特 773E 自卸车于 2011 年投
入使用，累计平均运行 29000h。为保障生产任务的完成，需引进运输车辆参与剥离生产。经对云南类似
露天矿山的同力、临工、宇通等品牌矿用宽体自卸车的实地考察，将具有国产特色的矿用宽体自卸车定为
试用车型，通过使用为下一步车辆更新选型提供依据。

Abstract： The 40 transport vehicles in use at Kunyang Phosphorus Mine have all entered a period of failure and loss, the operation rate has dropped,
the failure rate has increased, and the operating cost has increased year by year. Among them, Komatsu HD325-6 dump trucks were put into
use in 2007 and have accumulated an average of 33,000 hours of operation; 20 Caterpillar 773E dump trucks were put into use in 2011, and
have accumulated an average of 29,000 hours of operation. In order to ensure the completion of production tasks, it is necessary to introduce
transportation vehicles to participate in the divestiture of production. After ﬁ eld investigations on the wide-body d
