摘要
为了解决杜儿坪煤矿采空区自燃以及瓦斯超限的耦合治理问题。利用Fluent软件对抽采前后情况下的采空区进行数值模拟研究,得出在抽采情况下采空区自燃三带区域的变化,也为62711工作面的防灭火提供理论基础。
In order to solve the problem of coupling control of spontaneous combustion and gas overrun in the goaf of Duerping coal mine. The Fluent software is used to simulate the goaf in the case of before and after the extraction, and the change of the spontaneous combustion three-zone area in the goaf is obtained, which also provides the theoretical basis for the fire prevention of the 62711 working face.
