Abstract
The article presents comparison of the values of maximum permissible concentrations, revealed during the analysis of the national standards of Russia and Australia in the field of regulation of nitrogen oxides. The impact of poisoning of the workers of the quarry with nitrogen oxides after blasting operations are presented. A detailed review of studies of methods for reducing nitrogen oxide emissions is given. The way of decreasing emission of nitrogen oxides using highly active catalysts as a part of the profiled tamping is offered. Laboratory studies were carried out using a model explosive and pentaerythritol tetranitrate. The results obtained showed that zinc carbonate (ZnCO3) is the most effective. The reduction in the amount of nitrogen oxide emissions was 40% of that released during experiments without the addition of catalysts.
Highlights
IntroductionThe modern world is a huge and complex mechanism in which such areas as IT, extraction of mineral resources and their processing are permanently developing [1,2]
It can be seen that by having considered the results obtained, it can be argued that the effectiveness of the use of catalysts as part of a contoured stemming in order to reduce emissions of nitrogen oxides released after blasting operations has been confirmed
An important aspect is the obtained results of laboratory studies associated with the use of a real explosive instead of a model explosive, pentaerythritol tetranitrate (PETN), in order to prove the feasibility of using methods to reduce nitrogen oxide emissions
Summary
The modern world is a huge and complex mechanism in which such areas as IT, extraction of mineral resources and their processing are permanently developing [1,2]. These directions constantly intersect and complement each other [3,4]. It is important to note that the development of the mining industry inland makes it possible to pursue an economic policy in the field of import and export of extracted resources, which is an integral part of the GDP, and, the sustainable development of the state itself [10,11,12]
