Исследование перемещения разнопрочных горных пород взрывами скважинных зарядов

Аннотация

Subjects of research: object of research arc empty different strongly compacted rocks Dzhcroj-Sardara deposit of phosphoresces. Purpose of work: consists in moving different strongly compacted rocks by explosions borehole of charges at the expense of increase of efficiency of explosion based on redistribution energy saturation blown up horizon and change of character of interaction of charges. Methods of research: the job is executed with application of a complex method of researches including theoretical generalization, experimental researches in industrial conditions with use of mathematical modeling, and also mathematical statistics and correlation analysis. The results obtained and their novelty: the way of moving of compacted rocks by explosion raising a production efficiency of the directed explosions boreholes by charges blasting matter on dump is developed, which scientific novelty consists in use short boreholes of charges which arc taking place in strong inclusions for an effective utilization of their energy and differential of influence on a file in different strongly compacted rocks, expenses, ensuring decrease, for their splitting and moving to the produced space, on the basis of which the technique of their engineering account is developed and the patent №IAP 04242 from 06.09.2010 is received. Practical value: the technique of definition of factor of dump is developed at moving different strongly compacted rocks by explosions boreholes of charges in industrial conditions and way of moving different strongly compacted rocks in internal warehouse by explosions boreholes of charges. Degree of embed and economic effectivity: the developed way is introduced on dig area of Tashkura of the Dzheroj-Sardara deposit of phosphoresces of Navoi mining metallurgical combine. As a result of introduction the economic benefit at a rate of 505,172 millions sum per one year is received (112,3 sum on 1 m3 empty of compacted rock (in the prices of 2011)). Field of application: mining industry.
