METHOD OF CONTROL OF AREAS OF EARTH SURFACE SINKS ABOVE POTASSIUM ORE MINES

摘要

mining. SUBSTANCE: subsidence phenomena are detected by skeleton and area geological routing survey. Then, bedrocks are drilled-in and morphology of native bed surface in subsidence places is revealed. At the same time, dynamics of manifestation of exogenic geological processes is determined by decoding of aerospace photomaterials of different years and by observation of profile lines of surface and deep reference marks. Structure and state of water-protecting ground mass are studied with help of nonexplosive high-resolved seismic exploration by method of common-depth point with geomechanical analyses, on its results, of stressed-deformed state of massif. Hydrodynamics of above-salt waters is controlled by measuring level of underground waters in hydrogenological observation hole. In course of hole drilling, rock samples are used for determination of their physicomechanical properties. EFFECT: provided prognosis of development of negative processes of technogenic-natural genesis of undermined territories.
