Abstract This paper summarizes the computer applications in open-pit mine planning at the Iron Ore Company of Canada (IOC). A brief history of the use of computers at IOC is given, and a description of the existing facilities is outlined. The following systems are discussed: storage and retrieval of geological data; geotechnical data analysis; long-term grade and tonnage forecasting; ore grading; and open-pit mine design. Justification for using computers in open-pit mine planning is given, and possible future areas of application are considered.
Keywords: Open-pit mining, Computers, Mine planning, Iron Ore Company of Canada, Geological data, Geotechnical data, Slope design, stability analysis, Dewatering, Grade estimates, Tonnage estimates.
