Study on the sliding mechanism of the external dump slope in the open-pit mine with wind-blown sand base.

Wind-blow sand (WBS) is widely distributed in the "Desert Gobi" region. This study is aimed at exploring the mechanism of how different thicknesses of the WBS layer influence the slope movement of external dumps in open-pit mines. To achieve this aim, the slope of the external dump in the open-pit mining area of Panel 3 in Daliuta Coal Mine was taken as the research object.
