A Review of Operations Research in Mine Planning
نویسندگان
چکیده
Applications of operations research to mine planning date back to the 1960s. Since that time, optimization and simulation, in particular, have been applied to both surface and underground mine planning problems, including mine design, longand short-term production scheduling, equipment selection, and dispatching, inter alia. In this paper, we review several decades of such literature with a particular emphasis on more recent work, suggestions for emerging areas, and highlights of successful industry applications.

Monitoring and assessment of pollutants resulting from bench-blasting operations
Nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (ANFO) explosive at the Sungun surface mine, located in the northwest of Iran. The pollutants were monitored during some blasting operations at the mine. It was concluded that the gases and dust clouds initially went up to the ...
متن کاملCut-off Grade Optimization for Maximizing the Output Rate
In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...
متن کاملA practical approach to open-pit mine planning under price uncertainty using information gap decision theory
In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...

LKAB’s Kiruna Mine is located above the Arctic Circle in northern Sweden, and produces about 24 million tons of iron ore per year, making it is the second largest underground mine in the world today. The orebody, a world-class high-grade magnetite deposit, is approximately 4 km long and 80 m wide on average, and lies roughly in the north-south direction, with a dip of some 60 degrees. Surface m...
