Flow field study on the restrained jet ventilation in mine chamber

Mine chamber is the necessary production-space in mining, and the chamber ventilation is the restrained jet in the limited space, According to the hydrodynamic and the jet theory, this paper refers to some problems on the flow field in three types of common mine chambers at the moment, and k-epsilon turbulence models of the chambers ventilation are established, and the boundary conditions of computation models are analyzed, and the airflow fields and velocity distributions in three types of mine chambers are simulated by Computational Fluid Dynamics (CFD). The results of numerical simulation show: the different types of mine chamber, the different flow field and velocity distribution, and the different efficiency of ventilation. The results of the simulation have been verified by the experiment, and will provide some useful guidance for studying the optimum design data and effective ventilation on the mine chamber ventilation.
