Study On Simulation And Prediction Of Temperature And Humidity Of Air In Machinery Transport Airway

The machinery transport airway commonly exists in coal mine. it is also the horizontal airway which has the most equipment and the most complicated heat & humidity source .It is bearing it not only a transport airway , but also be coal mining face's enter air way. It usually effect temperature, humidity and heat circumstance of coal mining face. This paper introduce heat source of high-temperature mine, briefly analysis the main heat source of Liang Bei coal mine. Take 11151 transport airway of Liang Bei coal mine for example; quantitatively analysis it's heat and humidity source and determining their nature. Do a research on the thermodynamic parameter variety law .based on these results; forecast the linear variety of temperature and humidity by improved Ping Song method. During this process, research the temperature of rock, the heat conductivity of coal and rock, convective heat transfer coefficient of air, heat discharge of coal on strap and wet ratio of surrounding wall etc. simulate the temperature field by applying the Fluent. By analyzing the forecasting and simulation result; bring out a method for forecasting and researching the temperature and humidity of horizontal airway. It has an important significance for heat-harm treatment of coal mine.
