包西铁路在陕北有红柳林接轨方案和大保当接轨方案。红柳林接轨方案在乌兰木伦河两岸通过大面积范围的煤矿采空区；大保当接轨方案无采空区，但通过风沙区，广泛分布的煤矿采空区及风沙区控制线路方案。通过对采空区和风沙区分布综合勘察，分析评价采空区稳定性和风沙区活动性及危害，并从工程地质条件、压煤、工程建设难度、工程投资对两大接轨方案进行综合比选，推荐投资较省的大保当接轨方案为贯通方案。

There were two track junction schemes for Baotou-Xi'an Railway in northern Shaanxi Province:the one was the scheme of track junction at Hongliulin district and the other was at Dabaodang district. If using the scheme of track junction at Hongliulin district, the railway would have to pass through large areas of coal goaf regions on either side of the Wulanmulun River; and if using the other scheme, there would be without any coal goaf region, but the railway would have to pass through wind-blown sand regions. So it was obvious that the route scheme was dominated by a wide range of either coal goaf regions or wind-blown sand regions. This study, focusing on that problem, and by means of comprehensive investigation, analyzed and evaluated the stability of the coal goaf regions, the activity of the wind-blown sand regions, and the harms arising from them. Furthermore, comprehensive comparison with each other of the two schemes was carried out in terms of engineering geological condition, coal mining situation, construction difficulty and project cost. Eventually, the scheme of track junction at Dabaodang district, with lower cost than that of the other scheme, was recommended by this study.
