The ventilation system is the basis to control the hazards in coal mine laneway. High reliability ventilation system can continuously convey fresh air into laneway , dilute the noxious gas, reduce disaster and ensure the mining productivity safe and effective. As we know that, many noxious gases in the coal mine laneway are compossible and their flowing states are complicated. In order to acquire the distribution characteristics of fluid movement, and evaluate the performance of ventilation system, a geometry and physical model of laneway was established in this paper with Fluent software, and the physical field of fluid such as velocity field, density field and temperature field were built and analyzed. A standard model was introduced to simulate the laneway fluid movement according to the turbulent kinetic energy equation and turbulent dissipation rate equation. The case study results showed that the CFD approach can effectively observe the performance of ventilation system and evaluate the safety and reliability of ventilation environment.
