Kalinichenko O. Scientific basis for the control of stress-deformed state of the array in the formation of the underground man-made structures.

Dissertation is devoted to solving the problems of development of scientific bases of control of stress-deformed state of the array by specifying the interaction of stress fields regularities in the formation of artificial underground structures. We propose a method that allows to predict the probability of formation of sinkholes collapse and its parameters over the open underground mining production areas. A system of elastic-plastic deformation of medium equations for calculation of stress-strain state of the rock mass, and the system functions, which determines the components of the tensors of stresses and strains in view of the laws of nonlinear continuum mechanics of rocks. "Giant-Gliboka" define the fundamental laws and set the key depending on the transformation of the stress-strain state of the example of the impact of the open space of the cleaning chamber 40 waste prolonged preservation of the mine. Established universal adaptive performance values of maximum stress in horizontal, tent, and inclined svodoobraznyhpotolochinah treatment chambers, depending on the development of depth, inclination and curvature potolochiny and differentiated strength of iron ore. It is proved that when developing rich iron ore at greater depths sublevel caving systems need to use vertical and inclined compensating chamber. In developing the rich iron ore development chamber systems at depths greater than 1,500 m key requirement is to move on tent and svodoobraznyepotolochiny that provide maximum stability under high rock pressure. The expediency of the introduction of high-performance environmentally friendly "frame-modular" technology combined with the laying of the exhaust chamber, providing decrease in the amount of deformation in the 77-81 % while reducing the cost of the identity of stowing operations at 43-54 % compared to a hardening bookmark. It is proved that for security monitoring ground surface within the mining allotment of mines, industrial and municipal facilities expedient to create a single data center surveying monitoring and geo-information centers on the subject of economic activity. This structure will ensure effective collection of relevant spatial information on the study area and create conditions for effective and qualitative solutions of strategic and operational objectives of safe operation of underground mines and the basin as a whole. A progressive release technology broken ore in blocks II pending contact with the filling mass chambers I queue, thus increasing the extraction of ore from the unit. The technological scheme of mining mine field area with trapezoidal base units and a combined tab cameras. Formulated the theoretical basis and the method of determining the economic risks from the possible violations of the earth's surface due to underground mining of iron ore.
