根据寺河矿4303工作面现状,基于非均质多孔介质渗流方程建立了对应三维的CFD模型。将采空区设定为连续性同向介质,通过设定边界条件和参数,模拟计算寺河矿采空区的瓦斯浓度分布规律,并得出回风巷和上隅角的瓦斯浓度。通过现场实测回风巷和上隅角的瓦斯浓度来验证模拟结果基本符合寺河矿的实际情况。

According to the situation of 4303 working face in sihe coal mine, based on the equation of heterogeneous porous media seepage corresponding three dimensional CFD model is established . Will set the goaf as continuity synthetic medium, by setting boundary conditions and parameters, the simulation calculation of sihe mine goaf gas concentration distribution, and return air lane and the upper corner gas con-centration. Through the field measurement of return air lane and the upper corner gas concentration to verify the simulation results basically accord with the actual situation in sihe coal mine.
