Optimization of mine ventilation and methane recoveryFunded under: ECSC-COALRES 7C
This report describes a computer simulation model which was developed to aid in the assessment of the optimum operational performance and design of a methane drainage system. The model solved compressible flow equations using the linear theory method, calculating the flow, pressure and purity of each pipe in the range. Two drainage systems of operational collieries were analysed using the program. In both cases an initial model was calibrated using underground data and the performance of the network assessed. To improve performance remedial measures and alternative system configurations were suggested. A personal computer (PC)-based version of the program was developed. Various mine ventilation strategies and previous research concerning the application of numerical techniques to solving ventilation networks were studied. A computer program was developed, based on one method which was found most suitable. Using the program, optimization analyses were carried out on the ventilation networks of two representative UK collieries. The exercises confirmed the applicability of the optimization method for the comparison of main and booster fan combinations. The exercises investigated the optimum total air power required to maintain the prescribed fresh airflows within the network.
