摘要: 采用Fluent数值模拟软件,选择标准双方程模型进行数值模拟,研究U+L型、U+I型通风方式下综放采空区瓦斯浓度分布规律。从数值模拟的结果看:U+I型通风方式沿走向、倾向和竖直方向的采空区瓦斯浓度分布规律与U+L型通风方式基本一致,相比较于U+L型通风方式,U+I型通方式可更有效的降低工作面和上隅角瓦斯浓度,起到了很好的瓦斯治理效果。
关键词: 综放工作面, 通风方式(U+L型, U+I型), 数值模拟
Abstract: The Fluent numerical software and the standard double equation model are adopted to do some research on the gas distribution rule of sublevel caving goaf under the ventilation method of U+L and U+I.According to the numerical simulation results,along with the trends,tendencies and vertical direction,the gas distribution rule of sublevel caving goaf under the ventilation method of U+I is consistent to the ventilation method of U+L.Compared with the ventilation method of U+L,the ventilation mehtod of U+I is capable of decreasing the gas conentration of the working face and the upper corner,so,perfect gas controlling effects can be obtained.
