成果简介	NOVELTY - Invention relates to mining, in particular to disposal of liquid industrial effluents located in cryolithozone of mining enterprises. Method for recycling industrial wastes of an enterprise in cryolithozone conditions includes studying the area of mining operations with the implementation of geological and geophysical studies of rocks to clarify the structure of the subsoil, hydrogeological investigations for calculation of possible natural water courses, drainage water coming from water-bearing formations to mine workings. Then the used pit is selected as the accumulator of utilized industrial wastes in the form of low-mineralized drainage water of the pit, mine and concentration tailing ponds. Numerical simulation of physical and chemical equilibrium and degree of saturation of waters interacting with open pit rocks is carried out. Mixing of technogenic waters from tailing dumps is simulated. Composition and mineralization of the obtained mixture is determined and then mixed with atmospheric precipitation. Numerical simulation of spatial tasks of geofiltration is carried out to determine the dynamics of movement of drainage water into the pit walls. Quality indices of mineralization and temperature of pumped water are studied at all stages of operation of a waste pit as a drainless accumulator. Observation wells are drilled. A technogenic water reservoir is created in the pit by pumping recycled industrial wastes. Through observation wells the state of the subsoil is monitored by observing the change in the piezometric surface of the water-bearing complex within the pit field and the chemical composition of the waters. Hydrochemical monitoring of surface watercourses and monitoring of dynamics of geo-temperature changes in cryolithozone rock thickness with determination of the level of safe filling of the worked-out pit with low-mineralized waters taking into account the subsequent natural filling with atmospheric precipitation and flood waters. USE - Mining. ADVANTAGE - Localization of technogenic load on the geological environment with significant reduction of hydrogenic heat flow into the thickness of permafrost rocks. 1 cl, 3 dwg
