海兰瓦利铜矿（HisnlandValleyCopper）公司现在开采两个低品位矿体──洛内克斯（Lornex）和瓦利（Valley）矿体。该公司成立于1986年。作为一种降低成本的措施，公司决定采用一套采场破碎和胶带运输系统，从瓦利露天矿向3km远、高出露天矿地表175的洛内克斯选矿厂运送矿石。该系统采用两台族回破碎机，向一系列带式输送机给矿．以最大运输能力130kt／d向主贮矿场运矿。本文描述了该采场破碎系统在目前配置方式下的运行情况，以及该系统至今的演变过程和今后的移设计划。
Hisnland Valley Coal now mines two low-grade ore bodies - Lornex and Valley. The company was founded in 1986. As a cost-cutting measure, the company decided to use a set of stope crushing and belt conveyor systems to transport ore from the Wael open-pit mine to the Lonex concentrator, 3km far above open-seam mine surface 175. The system uses two sets of back to crusher, to a series of belt conveyor to the mine. With the maximum transport capacity of 130kt / d transported to the main storage mine. This paper describes the operation of the stope crushing system under the current configuration mode and the evolution of the system so far and future plans for relocation.
