“…Constraint (11) ensures that shovels cannot be assigned to a face which is already mined, except if face was mined by itself and shovel is sitting idle. Constraint (12) ensures that if shovel 's' was assigned to face 'f' and to only one face in period 'p' , it will continue to be assigned to face 'f' in the next period.…”

“…The shovel allocation decision-making tool at this stage is required to optimise the operational objectives by providing optimal shovel placements and target productions. The scope of the existing multi-stage dispatching models [8][9][10][11][12][13][14] in the literature has remained limited to truck allocations for better operational results. The multi-stage model proposed by Soumis et al [10] provides shovel allocation decisions using man machine interaction, which render it unusable as a dynamic tool.…”

Mining optimization laboratory (Mol), university of alberta, edmonton, canada ABSTRACT The complexity and uncertainties associated with mining operations often lead to deviations from short-term plans. A proactive approach will predict such deviations and help minimise opportunity losses, providing economic and operational gains. This paper presents an optimisation tool as a dynamic shovel allocation decision-maker for mining operation simulation models. The objectives of the optimisation tool are to provide shovel allocations to mining faces in order to maximise production, meet desired head grade and tonnage at the crushers, and minimise shovel movements. This paper presents the development and implementation of the optimisation tool with an iron ore mine case study.

“…In another coal mine study by Temeng et al [12], they tackled the scheduling dispatch problem much differently-although it was a surface pit, their ideas could generalize to any complex logistics problem. They applied nonlinear goal programming theory to develop a software routine that maximized production (supply flow through the network in their case), subject to constraints which included maintaining ore quality characteristics.…”

This case study uses a surface mine to investigate multidisciplinary logistics analysis methods for improving refinery operations. Existing resource scheduling, inventory forecasting, and economic production quantity procedures have not been able to identify how to improve productivity. The objective was to locate and demonstrate proven techniques from operations research (and other related disciplines) which could be applied to solve logistics problems. Historical operations data along with a new sample (n = 140) were utilized for the analysis. Preliminary parametric tests failed, but later a multiple server queue model was developed by integrating nonparametric techniques, waiting line theory, stochastic probabilities, and break-even scenario analysis. Quantitative and qualitative data were analyzed, resulting in a solution to increase truck arrival rates by 10% which was projected to increase refinery utilization by 7-77%, thereby generating a potential productivity savings of $161,223.31 per year.

“…Temeng and others contributed greatly to the theory and practice of automotive mining machinery usage at open-pit facilities. In their papers they determined the sphere of haul truck efficient use in open-pit mining [1,3,5,[8][9][10], summed up the experience of its operation [2,4,7,[11][12][13][14], highlighted the issues of techno-economic studies devoted to automotive mining machinery usage efficiency [1][2][3][4][5][6][7][15][16][17].…”

Abstract. Theoretical and methodological fundamentals of mining haul trucks optimal design are articulated. Methods based on the systems approach to integrated assessment of truck technical level and methods for optimization of truck parameters depending on performance standards are provided. The results of using these methods are given. The developed method allows not only assessing the truck technical levels but also choosing the most promising models and providing quantitative evaluations of the decisions to be made at the design stage. These areas are closely connected with the problem of improvement in the industrial output quality, which, being a part of the widely spread in Western world "total quality control" ideology, is one of the major issues for the Russian economy.
