Abstract

Hongtoushan copper mine was studied by analyzing the type of heat source, the calculation method about thermal releasing in stope, thermal transfer between rock and air, distribution of temperature in stope were formulated. With CFD (Computational Fluid Dynamics, DFD) simulation and Fluent software, geometrical model of a stope was built, boundary conditions was initialized, then the temperature distribution, velocity and pressure field, concentration of oxygen and CO2 of air were simulated. In order to validate the simulation result, the parameters of the stope were measured with meter, and comparing with the data of simulation. The result shows that the data of measuring and simulating are compatible. According to the distribution of temperature and velocity, some ways such as flow angle and flow velocity are put forward, simulation and parameter optimization made also, a satisfied result is acquired. The conclusion can be used on ventilation designing and stope improving.
