平坦沙丘地形场地竖向设计特点探讨

Discussion on Features of Flat Terrain Dune Site Vertical Design

由于自然地形平坦,位于沙漠、戈壁滩、草原的矿井工业场地,局部区域排水方向不明确,给场地的排水方向、场地控制高程、平场坡度等要素确定带来一定的难度。通过对地处陕北毛乌素沙漠地带的可可盖煤矿工业场地的竖向设计及优化的过程的论述,提出了一种针对地表径流方向不明显的平坦地形条件下的工业场地竖向设计方法。

For the mine industrial site in natural flat terrain, such as deserts, Gobi desert, and grassland, the local drainage direction is not clear, which brings certain difficulty for the site drainage direction, site elevation control, and the flat - field gradient determination. The vertical design and optimization process for industrial site of Kekegai Coal Mine were introduced, which located in Mu Us Desert area in North Shaanxi. A vertical design method of industrial site was proposed for flat terrain with unclear direct surface runoff direction.
