的路面材料。通风平巷的断面根据通过的风量和允许的风速确定。平巷的断面形状根据围岩的稳固程度、服务年限和支护材料供应条件等确定不支护的或用混凝土、锚杆、喷锚、石材等支护的巷道断面为拱形;木材支护的巷道为梯形;在侧压力大的软岩或膨胀岩石中的巷道，也有采用圆形的或曲线形断面的。通风平巷的壁面应力求平整光滑。 (陆礼锰)P{ngx{ong平巷(drift)沿矿体走向布置、不直接通地面的水平巷道。位于矿体中的为脉内平巷，位于围岩中的为脉外平巷。平巷的坡度根据运输和排水的要求确定，一般为3%。一5%。。平巷按用途分为运输平巷、通风平巷、探矿平巷、放水平巷、充填平巷等。通常主干运输平巷和通风平巷用脉外平巷;探矿或使用年限很短的采矿平巷用脉内平巷。运输平巷分有轨和无轨两种，断面尺寸根据运输车辆的外形尺寸、人行道和水沟宽度、必要的安全间隙等因素确定。有轨运输平巷设有轨道，根据运输量大小确定采用双轨或单轨。无轨运输平巷一般为单车道;按行车密度、车速和使用年限采用不同
