| As the development of society and industy, more mine resoure is mined, the depth of mine is also expanded. meanwhile, there is a bad phenomena-high temperaure come out in deeper mine, the high temperature problem highly threaten the safety of mine in production and affect the healthy of labour force, restrict the economic benefits of mine enterprise. In light of National Mine Safety Law, improving the hight temperature is the essential for the safety and enhancing the labour benefits in mine.The paper preliminary introduce the state of high temperature in mine and the harmful influence to safety of producing and worker's health, meanwhile, the paper present the leading technology for the high tempereature and thermal harm in deep mine. Recollecting the simillar research reference at home and abroad, heat exchange theory and development level is summarized for mine. According the heat exchange heat theory between airflow and rock wall utilize the Computational Fluid Dynamics, Computational Heat Transfer theory etc. As the mine area -785 Middle drilling chamber for study, utilize the FLUENT software which is the most popular Computational Fluid Dynamics in world to analyze and study the flow field, temperature field and relative humidity field. For test and verify the feasibility and veracity of numerical simulation, the airflow velocity, temperature and relative humidity is measured. It's valid and scientific with FLUENT numerically simulate the local ventilation inside the drilling chamber by arranging and analyzing the measure data, its results will support the thoery which is apply to optimizational design for mine ventilation system in the future.Based on the numerical simulation with the FLUENT software for local ventilation in the drilling chamber, the better aeration-cooling is choosed. and based on the former ventilated scheme, the design of local ventilation system is adjusted and optimized for the mine area -785 Middle. |
