The paper briefly characterizes mining conditions at open-pit mining operations of UK Kuzbassrazrezugol JSC, as well as dependences of the man-made impact of blasting operations depending on the influencing factors. The obtained dependencies can be used in formation of a digital multifactor model of man-made environmental impact of blasting operations. The ways are considered to safely increase the volume of simultaneously blasted rock mass. The article shows the dependence of changes in the load on the atmosphere with from the blast center, the weight of simultaneously blasted explosives in surface mining operations, as well as the dependence between the yield of fines and the size of the gap between the charge and the charging chamber. Reducing the specific consumption of explosives, energy intensity of mining, the man-made impact of blasting operations on the environment, as well as increasing the hazardous zone range - all of this can be achieved by using charges placed in hoses of variable diameter that would ensure a gap between the charge the the borehole wall when blasting wet and dry rock masses. It was extablished that one of the ways to safely increase the volume of simultaneously blasted rock mass is the introduction of energy-saving environmentally friendly technologies in production and use of industrial explosives, which would ensure higher completeness of chemical transformations and the efficiency of the blast through the use of special fuel mixtures containing surfactants instead of diesel fuel in the compositions of granular industrial explosives, as well as changing the rheological properties, morphology of the industial explosive components, stability and energy intensity of explosive charges at zero oxygen balance due to increasing the contact area of the fuel and oxidizer by several orders of magnitude.
