Geophysical monitoring of the development of stress-deformed ore massives

Abstract

Relevance. Topical issues of rationalization of nature management are considered, including the establishment of the magnitude and regularities of the ecological risk of technological processes, the assessment of the communication processes of technogenic products and the prediction of the ecological dependence of biota on mining during the underground development of the deposits of the Sadonsky ore cluster. The Aim of the research is to comprehensively study the interaction of natural and technical systems that ensure the geomechanical balance of massifs in the area of subsoil development by systematic monitoring of the stressstrain state of the massifs using the methods of complex generalization, analysis of practical experience and scientific achievements in the field of underground ore mining in the massifs. Complex structure, theory and practice of destruction of solid media by means of continuum mechanics and mathematical statistics with the development of economically and environmentally acceptable options for the extraction of metal ores. Methods. The results of modeling the state of ore-bearing massifs on optically active materials are presented. A reliability factor is proposed for assessing the safety of mining technologies for the development of critical stresses and deformations. Results. An adequate relationship has been established between the nature of the force impact on natural and artificial massifs and their stability with the correlation between the strength of the massif and the safety of the earth’s surface, as a guarantor of the safety of biosphere ecosystems. The results of modeling the tension of the massif by the finite element method, the distribution of pressure along the contour of the excavation on the support and the study of the filtration heterogeneity of ores crushed for leaching purposes according to the propagation velocity of stress waves are given. The results of the analysis of retro- and prospects for the development of methods for managing the state of rock mass in the development of fields are generalized. A conclusion is made about the possibility of ensuring the optimal stress ratio in the elements of the geomechanical system by geophysical methods within the framework of monitoring the state of the rock mass and underground workings. Taken together, the recommendations represent a program for the recovery of the region’s mining enterprises from a protracted crisis and the restoration of the former potential of one of the flagships of nonferrous metallurgy, the implementation of which creates an economic, environmental and social effect in a depressed industrial region.
