歪头山铁矿属于大型露天矿,矿山年产矿石300万t,采剥总量在1200万t左右。当前矿山生产经营面临诸多不利因素,主要是主体设备老化,设备效率低;汽车运输能力不足,新水平准备周期长;生产运输工艺系统复杂,设备配置不合理等诸多情况。矿山的生产经营成本较高。而铲装运输系统是矿山生产中最重要的环节。对于歪头山铁矿来说,它是集采、运、选为一体的综合性矿山,矿山主体设备种类较多,确定合理的车铲配比尤为重要。只有这样才能最大限度地降低电铲欠车和车辆待装时间,提高设备效率,改善车铲利用,从而达到整个工艺系统的优化。
Waitoushan iron ore is a large open pit mine, with an annual output of 3 million tons of ore, mining stripping total about 12 million t. The current mine production and management are facing many unfavorable factors, mainly the aging of the main equipment, equipment, low efficiency; lack of motor transport capacity, the new level of preparation cycle is long; complex production and transportation system, equipment configuration and many other irrational. Mine production and operation costs are higher. The shovel transport system is the most important part of mine production. As for the Waitoushan Iron Mine, it is a comprehensive mine integrating mining, transportation and selection. There are many types of equipment in the main body of the mine, and it is particularly important to determine a reasonable ratio of the shovels. Only in this way can we minimize the number of vehicles and vehicles waiting to be off the shovel, improve equipment efficiency, improve car use, so as to achieve the optimization of the entire process system.
