Taking a specific deep open pit mine as the research object, the physical model of the deep open pit mine is established by using Gambit software, and after gridding, the air flow law and temperature field distribution in the pit of the deep open pit mine under different heat release, different positions and different natural wind speeds are numerically simulated by using Fluent software. The results show that the increase of heat release from mechanical equipment will lead to the decrease of air velocity and the decrease of complex circulation intensity in the stope, which will make the heat unable to be effectively discharged and the overall temperature of the stope increase to form a high-temperature mine. The space-time air velocity ratio of the mechanical equipment area on the windward side is larger than that on the leeward side, that is, the heat dissipation effect of the equipment on the windward side is better than that on the leeward side.

摘要

Taking a specific deep open pit mine as the research object, the physical model of the deep open pit mine is established by using Gambit software, and after gridding, the air flow law and temperature field distribution in the pit of the deep open pit mine under different heat release, different positions and different natural wind speeds are numerically simulated by using Fluent software. The results show that the increase of heat release from mechanical equipment will lead to the decrease of air velocity and the decrease of complex circulation intensity in the stope, which will make the heat unable to be effectively discharged and the overall temperature of the stope increase to form a high-temperature mine. The space-time air velocity ratio of the mechanical equipment area on the windward side is larger than that on the leeward side, that is, the heat dissipation effect of the equipment on the windward side is better than that on the leeward side.
