FIELD: mining industry, underground development of deposits of mineral wealth with filling of worked-out space. SUBSTANCE: method of filling of worked-out chambers includes installation of insulation bridges with water passage elements and supply of pulp into chamber through conduit. Filtration layer is formed in lower part of chamber. Water drainage from chamber is arranged from its upper part distant from point of pulp supply and filled mass is dried by means of filtration with drainage of water through water passage elements. Water can be drained out of chamber under pressure of pulp column in supply conduit, pulp can be fed along flank of chamber. EFFECT: development of productive method of hydraulic filling of worked-out chamber which ensures qualitative clarification of water, high density of filling mass and low energy consumption for lift of water from mine. 2 cl, 2 dwg |
