Applied Physics and Mathematics Annotation << Back Explosion and geotechnology:contradictions and problems Galchenko Yu.P. The main feature of the mineral complex is destroyed and issue to the earth’s surface of huge masses of rock are comparable in magnitude to the total amount of a substance in a biological turnover of all land ecosystems of our planet. State of the rock mass in the area of direct anthropogenic impact is determined by features extraction processes of minerals, being set required for this inevitable action. Explosive destruction of rock mass is in the foreseeable future, the only candidate of technological development mineral complex in the growing conflict between the increasingly complex requirements of geotechnology and limited control of the allocation and distribution in the array of explosive energy. The influence of the internal contradictions of the existing methods of technological explosion reduces the effectiveness of breaking and mining. Partial resolution of these conflicts is achieved considering the influence of the scale factor and using the ideas of destruction of rock massifs deconcetrated charges. Key words: the mineral resources sector, explosive demolition, rock mass, the contradictions, the methodology, the scale breaking, deconcentration charges fragmentation efficiency.
