补充资料：横巷
横巷
cross cut
触ngxlong横巷(c ross cut)在地下矿开拓中，不直接通地面、且横穿矿体走向的水平巷道。又称穿脉。坡度一般为3%。一5%。。按用途、分探矿横巷、运输横巷、装矿横巷、通风横巷等。探矿横巷是用来探查矿体的数量、厚度、产状、矿石质量和工程地质特征的;如果不考虑将来在采矿时利用，可以采用1.sm火Zm或更小的断面;如果考虑将来采矿时要利用，则应与运输横巷的断面规格一致。运输横巷是用来与沿脉运输平巷构成环形运输线路的。装矿横巷是为某些采矿方法的采场出矿而设置的，多数是利用运输横巷作装矿横巷。断面主要决定于运输设备的规格和必要的间隙。用无轨设备运输时，用单车道;用有轨设备运输时，铺单轨。通风横巷是用来沟通通风网路，向采场送风或自采场排风的。其规格取决于通过的风量和允许的风速。 横巷的断面形状根据围岩的稳定程度，服务年限和所采用的支护材料而定。围岩不稳固或服务年限长的，以及支护材料为混凝土、喷锚、石材的，一般采用拱形。在侧压力很大的软岩或膨胀性岩石中，也可采用圆形。用木材支护的，一般采用梯形。 (陆礼铸曾耀)
