【摘要】：基于計算流體動力學(CFD)和礦井通風理論,以田陳煤礦7309綜掘工作面為研究對象,建立了單一壓入式通風系統(tǒng)條件下的綜掘工作面幾何模型。采用FLUENT軟件對不同供風速度下綜掘工作面三維空間內風流場、溫度場及濕度場的分布特性及變化規(guī)律進行數值模擬。模擬結果表明:增加供風量對降低巷道溫度有一定的作用,但對巷道內的濕度影響較小,當壓風筒出口風速為16 m/s、風量為480 m3/min時,綜掘巷道內的溫度低于26℃,綜掘機附近工作區(qū)域相對濕度保持在40%~57%之間,此時的供風參數滿足煤礦安全規(guī)程要求。
[Abstract]:Based on the theory of computational fluid dynamics (CFDs) and mine ventilation, the 7309 fully mechanized excavation face of Tianchen Coal Mine is taken as the research object. The geometric model of fully mechanized excavating face under the condition of single pressure-in ventilation system is established. The air flow field in three dimensional space of fully mechanized excavating face with different velocity of air supply is analyzed by FLUENT software. The distribution and variation of temperature field and humidity field are numerically simulated. The simulation results show that increasing air supply plays a certain role in reducing tunnel temperature, but has little effect on the humidity in roadway. When the wind velocity at the outlet of the pressure tube is 16 m / s and the air volume is 480 m3 / min, the temperature in the roadway is lower than 26 鈩，
