摘要: 根据寺河矿XV1301综采工作面的并列双U型通风现场的实际情况,建立了流体力学模型,模拟对比分析了若XV13013主进风巷风量不变的情况下不同比值的XV13011辅助进风巷风量和XV13015另一进巷风量对采空区流场及瓦斯运移特征的影响。研究表明在并列双U型通风方式下,若XV13011辅助进风巷风量和XV13015另一进风巷风量配比为3:1时,能够明显地减少采空区大量的瓦斯随漏风涌向上隅角,从而可以使流经上隅角和主回风巷的瓦斯减少,缓解瓦斯积聚问题。并且这一研究为瓦斯治理和风量配比优化提供理论依据。

Abstract: According XV1301 mechanized mining face parallel double U-ventilated actual site conditions in SiHe. The hydrodynamic model are established to simulate the comparative analysis of the main intake airway if XV13013 case of constant air volume ratio XV13011 different auxiliary inlet Lane XV13015 another intake air flow and air flow lane on the flow field and goaf gas migration characteristics. Studies have shown that parallel double U-ventilation, if XV13011 auxiliary inlet air volume and XV13015 another lane into the wind air volume ratio of 3:1, Alley, can significantly reduce the upward corner gob centralized air leakage, which can effectively alleviate the upper corner and the main return airway gas accumulation phenomenon. This study is the ratio of gas and air flow control optimization theory.
