布置高抽巷后采空区瓦斯运移数值模拟

he study clearly fully mechanized top coal mining mode after the layout of the high pumping Lane Gob gas migration law has to focus on the appropriate drainage measures to effectively control the face of the gas concentration, improve the drainage pipes Concentration, the introduction of computational fluid dynamics CFD to this new technology. The simulation results show that near the inlet side of the gob Lane shallow, relatively low gas concentration, the more close to the return air side, the higher the gas concentration, and with increasing distance from the face, gob gas Concentration increasing. The fully mechanized top coal gap after more fresh air flow into the face of high pumping Lane, extraction of high pumping Lane Goaf to a certain extent.
