Abstract: In mine industrial site such as deserts, the Gobi desert, grassland, as the natural terrain is too flat, local drainage direction is not clear, for industrial site vertical design brings a certain degree of difficulty.By surface model of the type of terrain, clear direction of the drainage of the site;Using different height projection surface of the terrain below, determine the site low control elevation; Finally taking the site General layout flat soil surface1 and flat-field gradients, optimized site vertical design and earthworks.

Key words: Site vertical design, optimization of site earthwork, the lowest elevation slope, flat field, flat terrain dunes
