Research on Dstribution Law of Gas Flow Field and Buried Parametersin Goaf

针对马堡煤业“U”型通风工作面上隅角瓦斯超限频繁,严重制约安全高效生产的难题,通过FLUENT软件模拟得到马堡煤业综采开采条件下采空区瓦斯分布,研究现采采空区瓦斯流场分布规律,结合现场试验考察,得到具有指导意义的综采采空区瓦斯运移规律和合理的采空区埋管参数。

According to the problem of the gas content over limit frequently in the upper corner of the U type ventilation in the underground mine and seriously restricted the safety and efficiency of coal production,Through FLUENT simulation,the gas distribution in the mined-out area under the condition of fully mechanized mining in Mabao Coal Industry was obtained,and the gas flow field distribution rule in the mined-out area was studied.Combined with on-site experimental investigation,the guiding gas migration rule in the fully mechanized mined-out area and reasonable buried pipe parameters in the mined-out area were obtained.
