摘要： 针对大倾角特厚煤层综放工作面回风平巷大范围失修、回采期间上分层采空区有害气体渗出和矸石窜入等问题，并基于煤矿采动破碎岩体高渗透、Darcy渗流等特性，对回风平巷与上分层运输巷(采空区)之间的煤柱厚度进行了设计研究，并得出回风平巷的合理布置位置，分为四大类位置和两小类位置。
关键词: 大倾角, 特厚煤层, 回风平巷, 巷道布置, 煤柱厚度
Abstract: Aiming at the Steeply Dipping Thick coal seam fully mechanized working face air return Tunnel Fall into disrepair, Originate from gob The upper section goaf gas seepage and Gangue falling In mining period，Based on the broken rock and coal mining, seepage properties of high permeability Darcy, Researched on Pillar Thickness between air return Tunnel and transportation Tunnel (gob)，at last Obtain of the Reasonable layout of air return Tunnel，Divided into four main categories position (I, II, III, IV), two small (Class III - I - II, III).
Key words: Steeply Dipping Thick coal seam, the layout of air return Tunnel, Darcy flow, Pillar Thickness
