Capping operations of minerals are carried out by mining at the distance from the point of exit line crossing with the line of the sand surface contour to the point of crossing of the ledge slope line with the line of sand surface contour. And peat components of the inner exit are removed layerwise in a top down manner by longitudinal entries of a bulldozer with their further transportation into dumps.EFFECT: increased efficiency of capping works by a bulldozer method.5 dwg |
