Underground development of ore deposits with conservation of the ground surface

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...
