| 摘 要： | "Y"型通风方式能够较好地治理工作面上隅角和采空区瓦斯问题,但现场直接测定采空区漏风场和瓦斯流场很困难。通过建立二维解算模型,应用计算流体力学软件fluent对采空区漏风场和瓦斯浓度场分布进行了数值模拟研究,并对不同主副进风巷配风比进行了综合比较,得出配风比为5∶1时瓦斯治理效果最好。

| Abstract: | The Y-type ventilation is a better way to control the upper corner and gob gas,but the direct determination of air leakage field and gas flow field in gob is very difficult.This paper establishes a two-dimensional calculation model,the distribution of air leakage field and the gas concentration field in gob are studied by using CFD numerical simulation software,then a comprehensive comparison is carried out about different air volume distribution ratio between main and auxiliary air roadway.it obtained that gas control effect is the best when air volume distribution ratio is 5:1. |
