| 摘 要： | 我国绝大部分采煤工作面均采用"U"型通风方式,其落山角是采空区瓦斯的集中涌出区域。本文通过对综采工作面落山角瓦斯来源和瓦斯超限原因的分析,探索出一套"两进两回"治理落山角瓦斯的通风方式。该方式能有效提高局部积聚区域内瓦斯扩散强度,并能加强巷道中风流的瓦斯运移,治理落山角瓦斯简单易行、稳定可靠,有较好的推广应用价值。

| Abstract: | Most of China＇s coal mining faces have applied U type ventilation system, and the upper corner is concentrated area of gas emission. This paper analyzes the gas source in upper corner of coal face and the reasons of gas ultra limit, and then advances a set of ＂two-intake and two-return＇ventilation to deal with gas,which is accunmlated in the upper corner. This method can effectively improve the strength of gas diffusion,and can strengthen the gas migration in the wind tunnel. It is simple,stable and reliable,and has good application value. |

| Keywords: | upper corner gas controlling two-intake and two-return |
