摘要
利用有限元法分析了综放采场瓦斯巷和回风巷或运输巷采用“吕”字形布置后的卸压机理，得到了上部瓦斯巷宽度对下部回风巷或运输巷卸压效果的定量关系，为改革综放采场巷道布置并提高瓦斯巷抽放效果提供了新的设计思路和可靠依据．
The gas entry is always arranged on the top of air-drawing fully mechanized coal face. The depressing mechanism of top gas entry is analysized by the Finite Element Method(FEM), and the quantitation relation of width of top gas entry to the depressing effect of bottom air-out entry is also achived. A new design method and some reliable bases are put forword to realize the resonable layout of face entries and inprove the gas drainage effout of top entry.
