Research into man-made impact of rock blasting in surface mining of mineral deposits

The topicality of this research is defined by the increasing volume mining operations near settlements and production infrastructure, as well unit capacity haulage equipment and, consequently, growing rock mass simultaneously blasted prepared for excavation. Changes in conditions at UK Kuzbassrazrezugol JSC have been analyzed. A brief analysis results on various factors affecting degree man-made impact blasting presented. One ways to safely increase introduction energy-saving environmentally friendly technologies use plastic explosives, which would ensure higher completeness chemical transformations efficiency blast through special fuel mixtures containing surfactants instead diesel compositions granular industrial explosives. This will contact surface area oxidizer several orders magnitude stability energy-output ratio charges with zero oxygen-combustible balance. Reducing consumption energy intensity mining, environment, seismic action blast, radius hazardous zone - all can be achieved using placed hoses variable diameter when wet dry masses. article shows dependence changes load atmosphere distance from epicenter weight detonated explosives operations, between yield fines size gap charge charging chamber.
