Nikolashyn Y. The surveying control of the deformed processe for the forecast of stabikity of boards of deep opencasts

The dissertation is dedecated to the problems of edge stability in deep iron are quarries.In this work the mine surveying approach is developed: mining rack displacemt in open cast mining based on the conception of the forcast of the critical edge deformations in quarries.Complex destrueting mechanism and deformation conditions in prelimiting state have been found impact of softening process on ende shift deformation in deep quarries edges on the base of modelling rusults, large scale nature experiment implaying the light lenth metering, precision slopeotistanse metering, geomechanical and hygdrogeological observations.Lalent deformation techneques for determination for worked out endes complicated by funnel fornation are suggested as well as methods of control for by edge massif state in complex mining conditions, implemented in projecting and in the industry.
