METHOD OF STORING INDUSTRIAL WASTE Russian patent published in 1995 - IPC

FIELD: industrial waste treatment. SUBSTANCE: a method comprising the filling of dykes from coarse grain material, hydraulically depositing fine grain material by layer in the cleared space and draining water from the base of the fill features a novelty consisting in that coarse grain material is dumped on the outward slope of the dyke all the way down its height and along the perimeter of the fill after a first layer of fine grain material has been washed up and then the layers of fine and coarse grain materials alternate, starting with a fine grain layer and ending with a coarse grain one, so that a substructure is formed to give support to a next dyke to be deposited which is then overlaid with a fine grade layer hydraulically deposited at the outward slope of this successive dyke all the way down the height thereof whereby the substructure is of a width which is not less than that of the successively deposited layer of the fill at the base thereof. EFFECT: reliable protection of the environment against pollution by dust. 1 cl, 1 dwg
