Coal Production Scheduling Optimisation of Single Seam Open-Cast Mining

The paper presents new developments of the methodology of open pit coal production scheduling optimisation. They deal with the specific features of the exploitation of single coal seam and utilisation of truck-shovel and dragline systems. A production scheduling optimisation model is developed as a linear programming problem. The objective function maximises the net present value of the mining project under the technological constraints for meeting the demand function of the coal processing plant and effective utilisation of the available production equipment. Both principles of mine planning, coal quality optimisation and waste deferment are incorporated in the model. Results of a case study are provided to illustrate the applicability of the optimisation model.
