露天矿内减少采矿和运输设备停工和降低养路作业工作量的途径之一是消除由于轨距扩大所引起的列车掉道。在铁路移动线的上部结构仍为现有结构而矿山企业则加速推行轴重300千牛以上列车的情况下,在地质条件复杂的矿山为保证固定的轨距,要进行重新钉道并使用金属拉杆和轨撑,更换不适用的轨枕和扣件。但是
One of the ways to reduce the downtime of mining and transportation equipment and reduce the workload of road maintenance operations in opencast mines is to eliminate train lanes caused by the widening gauge. In the case that the superstructure of the railway moving line is still the existing structure and the mining enterprises accelerate the train with the axle load of 300 kN or more, in order to ensure the fixed gauge in the mine with complicated geological conditions, Tie rods and rails, replace unsuitable sleepers and fasteners. but
