总结国内外治理上隅角瓦斯的普遍方法,通过对比分析不同的通风方式治理采空区上隅角瓦斯的特点,利用Fluent软件对3D模型的采空区进行数值模拟,得出Y形和U+L形较U形对于治理上隅角瓦斯有较好的效果,工作面上隅角瓦斯浓度符合规程规定,为矿井安全高效生产提供理论指导。
Summarizes the common methods of harnessing the upper corner gas at home and abroad. By comparing the characteristics of different ventilation ways to control gas in the upper corner of the goaf, Fluent software is used to simulate the goaf of the 3D model, and the Y-shape and U + L shape is better than U shape for the treatment of upper corner gas. The gas concentration in the upper corner of the working face conforms to regulations and provides theoretical guidance for safe and efficient mine production.
