本文总结了加拿大铁矿公司(IOC)在露天矿规划和设计中应用计算机的情况。介绍了该公司应用计算机的简要历史,并概略介绍了现有的设备。讨论了下列系统:地质数据的存储和检索;工程地质数据的分析;品位和储量的长期予测;矿石分级以及露天矿设计。论证了在露天矿规划中使用计算机的合理性,并考察了计算机未来可能应用的范围。 This paper summarizes the case of Canadian iron ore companies (IOCs) using computers in surface mine planning and design. Describes the company’s brief history of using computers and gives an overview of existing equipment. The following systems are discussed: storage and retrieval of geological data; analysis of engineering geological data; long-term predictions of grade and reserves; ore grading and design of open pit mines. The rationality of using computers in surface mine planning is demonstrated, and the scope of the possible future applications of computers is investigated.
