摘要
宜兴煤业5309工作面采空区与5308工作面之间留设4 m窄煤柱,为了确定5309工作面采空区对5308工作面瓦斯涌出的影响,以便制定合理的瓦斯治理措施,文中分析了5308工作面的瓦斯来源,结合FLUENT软件对5309采空区注氮驱替的效果进行模拟,结果表明5309采空区注氮驱替能够有效控制其对5308工作面的影响。
4-metre narrow pillar is set between the goaf at 5309 working face and 5308 working face. To determine the influence of the goaf at 5309 working face on the gas emission at 5308 working face, the author proposes the nitrogen displacement to the goaf at 5309 working face to achieve the gas control at 5308 working face by the analysis of gas source and the effect numerical simulation with FLUENT software.
