CONCEPT OF SYNERGETIC INTERACTION BETWEEN ROCK BREAKAGE AND GEOMECHANICS PROCESSES IN MINERAL MINING

The purpose of the study is to develop, on the basis of the theory and practice of controlling the action of an explosion in various mining technical conditions, an idea of the concept consisting in elaboration of theoretical prerequisites and geomechanical support of new methods for deep-level rock breakage. In addition, our task was to determine how to effectively and safely solve specific technological production problems in mining at great depths. One of the aspects of the new conceptual approach for solving the problems of mining in complicated conditions, in particular, under induced seismic events and gas-dynamic phenomena is considered. The approach is based on interconnecting the geomechanics and rock fracture research, which allows the use of theoretical and experimental analogies and efficient interchange of appropriate instrumentations of the two methodologies. The scientific novelty of the research consists in development of mathematical models of rock deformation and failure at different scales under the influence of static and dynamic loads reproducing natural conditions. The modeling has shown shown that the explosion load of various design charges has different effect on stress-strain state of surrounding rock mass, which allows selecting charge design parameters such that mitigate blasting impact on geo-environment.
