海兰瓦利铜公司系一生产铜精矿与钼精矿的大型企业。矿山开采是用传统的电铲-汽车作业方式并配合以大型采场内矿石破碎与输送系统。两个矿体的矿石品位均很低(0.4%Cu、0.007%Mo),这就要求采矿量在26万t/d以上(剥采比为1:1)。为使矿山赢利,采矿成本必须保持在最低水平,因此,开采技术必须保持先进。除了采场内破碎系统之外,该矿还率先采用了电铲称量系统,与现代化汽车调度系统相配合。设备维修基本上是在矿山机修厂就地进行,汽车发动机和电动轮电机以及需要消除应力的一些大修理项目则由当地机修厂协助完成。电铲和汽车修理工作由矿山维修组承担。矿山的短期规划与长期规划均由矿山工程设计处设计编制。露天矿边坡设计、采后土地复垦以及爆破技术工程是请外部顾问协助完成的。
Highlander Copper Company is a large-scale producer of copper concentrates and molybdenum concentrates. Mining is the use of the traditional electric shovel - car operation and with a large stope ore crushing and conveying system. Both ore bodies have very low ore grade (0.4% Cu, 0.007% Mo), requiring a mining volume of more than 260,000 t / d (stripping ratio of 1: 1). To make mines profitable, mining costs must be kept to a minimum, and mining technology must therefore remain advanced. In addition to the crushing system in the stope, the mine pioneered the use of a shovel weighing system that is compatible with modern vehicle dispatch systems. Equipment repairs are performed on-site at mine mills, with automotive and electric wheel motors and some major repairs that require stress relief to be completed by local machine shops. Shovel and car repair work by mine maintenance team. Mine short-term planning and long-term planning by the mine design office design preparation. Open pit slope design, post-harvest land reclamation and blasting engineering are assisted by an outside consultant.
