Geomechanics of creating underground infrastructure during ore mining using emulsion explosives

Abstract

The monograph is devoted to solving the scientific problem of geomechanics of creating underground infrastructure during ore mining using emulsion explosives based on the established patterns of the formation of crush zones, intensive grinding and cracking around the charging cavity formed in a rock mass as a result of the explosion, as well as changes in the density and detonation velocity of emulsion explosives along the length of the charge column, formed at different angles of inclination of the wells. The established patterns form the basis of methods for calculating the parameters of drilling and blasting for creating underground infrastructure during ore mining, as well as calculating the performance of both emulsion and other industrial explosives based on the degree of detonation velocity. The monograph is intended for a wide range of engineering and technical workers, mining engineers, research and design organizations. Can be used in the educational process of institutions of higher and secondary vocational education when teaching disciplines in mining.
