智利科德尔科(Codeleo)公司是一个政府所属的公司,该公司从事采矿、工业贸易并经营位于丘基卡马塔(Chuquicamata)的世界最大的铜矿。1990年,科德尔科公司铜的年产量为68.2万t。该公司曾经针对丘基卡马塔铜矿的废石运输问题做过一次有关赢利性的调查,调查时对常规的汽车运输系统和一套采场内破碎加松散物料输送系统进行了比较,结果证明,后者是更合算的。1987年12月,由日本三菱(Mitsubishi)公司和德国克虏伯(Krupp)公司组成的联合体承包了整套废石破碎-运输系统的制造及安装工程。该系统包括目前世界最大的半移动式破碎站、7km长的带式输送机系统、一台卸料小车和一台排土机。此系统的平均生产能力为9000t/h,最大能力为9600t/h。废石的容重为2.Ot/m~3。
Codeleo, a Chilean company, is a government-owned company that engages in mining, industrial trading and operates the world’s largest copper mine in Chuquicamata. In 1990, the annual output of Copperco’s copper was 682,000 tons. The company had conducted a profit-seeking survey of the waste rock transportation at the Chukkarmata copper mine. The investigation compared the conventional car transportation system with a set of crushing and bulk material handling systems in the stope. The results Prove that the latter is more cost-effective. In December 1987, a consortium of Mitsubishi Corporation of Japan and Krupp of Germany contracted to manufacture and install a complete package of waste rock crushing-transport systems. The system includes the world’s largest semi-mobile crushing plant, a 7-km long belt conveyor system, a dump truck and a dump. The system’s average production capacity of 9000t / h, the maximum capacity of 9600t / h. The weight of waste rock is 2.Ot / m ~ 3.
