The use of extended cut mining with remotely-controlled continuous mines is increasing rapidly across the U.S. coal industry. The accompanying higher advance rates present problems such as higher levels of methane liberation and more dust generation at the face area during coal extraction. These circumstances give rise to many questions concerning miner health and safety. The design of an adequate mine face venitlation system, for the scenarios described above, requires considering the system in a three-dimensional, rather than a two-dimensional manner. Computational Fluid Dynamics (CFD) is a promising numerical simulation method that has the potential to solve three-dimensional fluid flow problems and to aid in the design of proper face ventilation arrangements. Validation of these results with experimental data is required before any CFD code can be used for design purposes. In this paper the authors will present a series of CFD simulations representing various face ventilation scenarios. Experimental data using a scaled (1:15) model in conjunction with the Particle Image Velocimetry (PIV) technique is being used for preliminary validation of these CFD results.
