Ulyts'kyj O. The prognosis of activization of strains of a mining array above old mining works at flooding mines

The dissertation includes a solution of an actual problem - establishment of singularities of a modification of hydro-geological conditions contains at closing group of collieries and geomechanical processes above old mining developments on small depthes with the purpose of the prognosis of a possibility of formation of failures and activization of process moving of a terrestrial surface. Is installed, that above old mining works the preservation in a steady condition of breeds of a roof is possible. In an outcome of filling of the produced space the geomechanical processes renew because of a diminution of durability of breeds and probably formation of failures above old mining developments and activization of process moving of a terrestrial surface. For prevention of these appearances it is recommended, that the level of flooding of mines was not above 150 m, and also the formula for the definition of magnitude of expected strains is offered.
