Is it possible to improve the quality of planning for open-pit mines?
Open-pit mine production scheduling (OPMPS) includes determining which blocks, within the final pit limit, should be mined each year and where the blocks should be transported, such as to a mill, trash dump, or stockpile, in order to maximize net present value (NPV). Long-term production planning for open-pit mine operations plays a key role in the assessment of mining projects. An important contribution in this field is presented in paper, wherein an algorithm developed that utilizes graph theory and dynamic programming to identify the ultimate pit limit that maximizes revenue. Furthermore, it is necessary to take into account various operational limitations when addressing this scheduling problem. The research, the results of which are presented on the pages of the journal "Mining Science and Technology", has shown that the use of alternative algorithms for calculating the block model of a quarry will improve the quality of field development planning.
