·The open pit mine production scheduling problem OPMPSP in the traditional T&S system consists of scheduling the extraction of a mineral deposit that is broken into a number of smaller segments or blocks across a horizon of several periods in order to maximize the total discounted profit known as net present value NPV from the mining
·The problem of long term production planning of open pit mines is a large combinatorial problem Application of mathematical programming approaches suffer from reduced computational efficiency due to the large amount of decision variables This paper presents a new metaheuristic approximation approach based on the Ant Colony Optimization ACO
·Long term block scheduling is a challenging problem that involves determining the best extraction period for blocks to maximize the net present value of the open pit mining business This process involves multiple constraints mainly ensuring safe pit walls and imposing maximum limits on operational resource consumption However most of the models proposed
·In most open pit mines material haulage costs can comprise over 50% of the total mining costs This portion can even increase as the future mining conditions will become more challenging
·A New Open Pit Mine Planning Optimisation Model Using Block Aggregation and Integer Programming vol 118 South African Institute of Mining and Metallurgy SAIMM Long term open pit mine production planning a review of models and algorithms Int J Min Reclamat Environ 22 1 2008 pp 3 35 /17480930601118947
·OPEN PIT PRODUCTION SCHEDULING 1 1 Purpose of Production Scheduling The purpose of open pit production scheduling is to obtain a series of ore and waste extraction schedules which meet the economic objectives of mine management over the mine s life The economic objectives of interest to management could be to maximize total profits from the
·The objective of this paper is to present and test the simulation optimization approach for short term mine production planning and scheduling with a focus on the MILGP optimization model To illustrate the The system considered in this model is an open pit mine with truck shovel operations The system includes trucks shovels plant
·to open pit mine production scheduling with stockpiling OPMPS S and provide a new linear integer model to solve this problem This model aims to improve the profitably of open pit mine operations in long term by determining which notional three dimensional blocks of ore and waste to extract and when and where to send them
·Effective transportation planning is crucial for the financial health of open pit mining companies Alarie and Gamache 2002 Studies estimate that transportation costs can account for up to 60% of total operating expenses and approximately 32% of all energy consumption in open pit mines Alarie and Gamache 2002; Sahoo et al 2014 Optimizing truck
