地下矿山掘进天井或斜井是矿山作业中最费钱、最困难和最危险的工作之一。酒钢镜铁山矿使用爬罐掘进天井,达到了安全可靠、经济效益明显的目的。我矿使用的STH-5型天井掘进机——爬罐,是瑞典阿利马克爬罐厂制造的,适用于掘进垂直的、倾斜的和弯曲的矩形、圆形断面巷道,我矿掘进断面为2.5×2.5(米~2),井筒高60米。爬罐主要由主机、辅机、安全保护装置及软管绞车等组成。操作者可在有保护伞的工作平台上作业,在罐内操纵主机上行或下行,停车时只要拨动凸轮制动器手柄即可。主机包括
Underground mining tunnels or inclined shafts is one of the most expensive, difficult and dangerous jobs in mining operations. Jiuquan Steel Tieshan Iron and the use of cantilever tunneling to achieve a safe and reliable, the obvious economic benefits. I mine used STH-5 Paver - Climbing cans, is the Swedish Allemag Climbing plant manufacturing, suitable for the excavation of vertical, inclined and curved rectangular, circular section roadway, mine excavation section 2.5 × 2.5 (m ~ 2), well 60 meters high. Climbing cans mainly by the host, auxiliary machines, safety devices and hose winches and other components. Operators can work on an umbrella-mounted work platform, manipulate the host up or down in the tank, and simply dial the handle of the cam brake while parking. Host included
