UNDERGROUND DEVELOPMENT OF ORE DEPOSITS WITH CONSERVATION OF THE GROUND SURFACE

Abstract

Introduction. In a market economy of particular importance are indicators of the quality of raw materials. Loss and decontamination of ores can be achieved by controlling stresses and strains using the residual bearing capacity of the fractured rocks with the primary condition of preserving the earth's surface of destruction. Goals and objectives. The purpose of the study is to substantiate the rational parameters of the technology of the geodynamic safety criterion. The goal is achieved by solving a complex of production due to technical problems, ensuring the correctness of the results, the assessment of geomechanical condition before the development of preventive measures of the impact of mining operations on the environment. Methods. Research methods include system and analysis of theory and practice results, experimental research and scientific forecasting. Results. The value of the criterion of optimum processing technology in the form of preservation of the earth's surface of destruction, such as guarantees of contact of the zone of destruction of the massif of mining, the zone of living matter, flora, fauna and Humans. A detailed understanding of the mechanism of interaction of the structural blocks of a discrete gravitational-tectonic-structural field. The mechanism of manifestation of the residual bearing capacity of the destroyed structural rock separations, the limitation of the degree value, the optimization of the mixture strength and the size of the pillars, the creation of geomechanical balanced segments with the minimization of the costs of the earth's surface condition control are specified. The proposed classification of methods of calculation of extent of the flat roof. The given classification of the methods of array management differs from the assessment of the state of the developed space during the work, after the end of the redemption, and not during the cleaning dredging. An example of the earth's surface conservation is given for the development of a flat-falling field, preserving the earth's surface without filling voids. Conclusion. The processes of control of the state of the masses and the earth's surface are their equivalent, which allows monitoring of the development of the field at all stages of the enterprise's existence. The use of geomechanical factors for the organization of mineral raw materials, mining tool for the implementation of resource-saving and environmental protection trends of mining production and reserve to improve the quality of the extracted ores when to ensure the competitiveness of the enterprise.
