Development of methodological approaches in modeling the properties of multicomponent granulites used in low temperature conditions and other complicating factors

The article addresses the questions of modelling the properties of multicomponent granulites to be used in conditions of low temperatures and other complicating factors. A methodical approach is used which is based on identifying a set of basic and indirect features that characterize the modelled multicomponent simple explosives as a complex object with essential features, distinctive properties, qualitative and quantitative characteristics, and technological indicators. An algorithm to modify the properties of multicomponent granulites was developed in order to solve the problem. This algorithm structurally separates the varying indicators and parameters in the manufacturing and application processes. Specific features of the used raw material components are shown as well as limitations in low-temperature applications. The effects of physical, mechanical, structural and other characteristics of granulite components on the explosive properties are shown, as well as the technical and technological aspects of production. The material mix of recycling materials formed in the processes of mining, concentration and processing of mineral raw materials is provided and the comparative efficiency of granulites is shown with account of cost indicators of the materials used. A method of desulphurisation during explosion of multi-component granulites is proposed which is aimed at neutralization of sulphur dioxide in the blast products. Natural and climatic factors, economic and geographical characteristics of the field location, geocryological conditions and characteristics of the permafrost soils are considered, as well as mining, geological and technical conditions of the development that affect blasting operations in the permafrost soils.
