斜坡道提升的线路设计中,经常碰到地形坡度是变化的,特别是斜坡较长的线路。对于下部坡度缓、上部坡度陡的线路,往往发生矿车“抬头”掉道,而使设计人员对上部坡道的坡度变化不敢取大。笔者发现,有的资料中,对缆车道的变坡设计和使用情况,进行了系统的总结,其经验都是很好的;但提出的变坡计算理论则是错误的,以 Ramp ramp to enhance the line design, often encountered terrain gradient is changing, especially the longer the slope of the line. For the lower ramp, the steep slope of the upper part of the road, often occur mine car “head ” off the road, leaving the designer of the slope of the upper ramp change dare not take big. The author found that in some materials, the design and usage of cable-way changing slopes are systematically summarized and the experience is very good. However, the proposed slope-changing calculation theory is wrong to
