Temperature Field Simulation And Airflow Optimization Of High-temperature Heading Face In Deep Mine

Deep mining is the trend of underground coal mining in China, while high-temperature in deep mine has brought a very negative impact for production of the mine. Improving the environment of heat deep mine is the major technical problem which need to be resolved for the current coal production and construction.By the computational fluid dynamics, heat transfer, air conditioning engineering and the flow field simulation theory, according to practical situation, the theoretical model of mine which can be used for actual analysis and calculation was proposed in this paper, and by the help of computational fluid dynamics software STAR-CD, the temperature and humidity fields within the roadway, as well as the distribution of velocity field were simulated. By field test data and software simulation of comparative analysis of the data to verify the correctness and accuracy of simulation software.In the meantime, according to the mathematical model, the situation of different flow are simulated, and inlet air temperature and wind speed and wind pipe imports outlet position of ventilating fans are optimized.This research provides basic data for analysis and prediction of heat and wet cooling climate, guiding mine cooling. While this are valuable for understanding of mine rock-degree field of temperature and humidity distribution and variation to guide mine production and improving the cooling efficiency...
