一、概况在国外金属地下矿,随着无轨运输技术的迅速发展,斜坡道得到了广泛应用。斜坡道运输机动灵活,为提高矿山生产能力和降低采矿成本开辟了新的途径。目前,矿山有与地表相通的主要斜坡道,也有阶段之间相连的辅助斜坡道。主要斜坡道是在有井筒运矿岩时,作为设备出入地表进行大修、通风 First, the general situation In foreign metal underground mine, with the rapid development of trackless transport technology, ramp has been widely used. Ramp transport is flexible and opens up new avenues for increasing mine productivity and reducing mining costs. At present, there are major ramps in the mine that are connected to the surface, and auxiliary ramps connected between stages. The main ramp is in the well bore ore transported, as equipment access to the surface overhaul, ventilation
