First proved the need for a confidence interval instead of the overload factor in determining the calculated surface deformation. Installed distributions confidence limits for strain and displacement position of the boundary of the basin. The algorithm for determining the calculated strain and achieve industrial inspection techniques, which confirmed a significant increase in the reliability of the results of calculations of displacement and deformation of the earth's surface. Variations in patterns of deformation of the array can be used in related areas, in particular to support the technology parameters of safe mining in high rock pressure. Improved method of calculation used to determine the deformation of the earth's surface as a result of underworking stope. The developed method will be used in paper industry in defining rules undermining natural objects and structures. The expected economic impact of the use of techniques in the practice of mining is 450 th. one working face annually. The potential effect reaches 10.5 mln. A new technique for determining the estimated strain has world novelty and has great social significance in view of improving the safety operation of structures and objects on the earth's surface.
