Analysis of Mine Face Ventilation Systems

Due to advances in remotely controlled equipment, longer cuts are possible in underground coal mines. However, with greater production comes an increase in environmental problems, including the generation of more dust. At the same time, higher levels of potentially explosive methane gas are liberated at the mine face during coal extraction. To dilute each of these problems, a large quantity of air is needed at the face of the excavation.

The use of various ventilation techniques in conjunction with these modern mining methods, leads to a complicated flow distribution (flow patterns) in the face area.Results of this research have shown that Computational Fluid Dynamics is an effective analytical tool for mining engineers to use in analyzing complex airflow fields at the mine face area and in examining contaminants transport. Ultimately the use of CFD will aid mining engineers to create safer, more productive, and environmentally friendly underground mines.
