摘　　要：贯屯煤层布置三条煤层大巷,为了便于系统的形成,首采工作面三个工作面巷道设计了5个风桥实现与大巷的联系,但存在施工慢、质量难以保证等问题。文章提出抬高工作面巷道联络巷布置层位,实现与大巷立交;回风巷采用联络巷跨越大巷,方便掘进胶带运输机的布置,实现了回采巷道优化。文章同时对大巷与工作面巷道的直角联系进行了优化。There were three seam roadways set in Guantun Mine. In order to form a system, five air bridges designed for the three mining gateways of the first coal mining face in the mine could realize the connection with the mine roadway. There were slow construction, difficult controlled quality and other problems existed in the five air bridges. The paper proposed that the level of the connection gateway of the miming gateway should be raised to realize the crossing with the mine roadway. The air returning gateway would cross over the mine roadway with the connection gateway, would be favorable to the layout of the belt conveyor for the gateway driving and could realize the optimization of the mining gateway. An optimization was conducted on the right angle connection between the mine roadway and the mining gateway.
