Justification of the possibility of using calculation methods to assess the intensity of pollutant emissions during mass blasting in coal open mines

Currently, coal remains one of the most popular energy resources worldwide, and coal mining, especially open-pit mining, annually leads to the degradation of significant areas, having a complex and long-term negative impact on all components of the natural environment. The source of the most intense salvo emissions in open-pit coal mines is blasting operations. It is impossible to perform an instrumental determination of the emission intensity during mass explosions, since the presence of people and equipment in the blasting zone is prohibited. Therefore, there is a need to use reliable calculation methods to determine the emission intensity in order to model the negative impact of mass explosions on the components of the natural environment. The paper analyzes the existing methods for calculating the emission intensity during mass explosions selects a method and calculates the emission intensity using model blasted blocks as an example, and verifies the obtained calculated values of the ground concentration based on the results of in-kind observations. This made it possible to give a comprehensive assessment of the feasibility of using calculation methods for the emission intensity during mass explosions in open pits and highlights a number of shortcomings and simplifications that require adjustment to improve the accuracy of the calculation.
