Abstract: A priority task for facilitating the development of the Arctic zone of the Russian Federation is to design new blasting technologies to be efficiently used in extremely difficult climatic, mining and geological conditions at remote operations. This is further motivated by the fact that up to 40% of Russia's gold reserves, 60–90% of its natural gas resources and 100% of its primary diamond deposits are located in the Arctic zone. The article analyses the problems of blasting operations while developing deposits in the Arctic zone. The main formulations of ordinary explosives are reviewed that allow to solve a number of challenges associated with blasting operations in remote and hard-to-reach Arctic regions. Based on the performed analysis of existing methods, further areas of research are identified that can improve the quality and safety of blasting operations: 1) determination of optimum weight and dimensions of boosters based on ordinary explosives depending on the initiating borehole size; 2) determination of the relation between the particle size / composition of the booster and the detonation velocity; 3) determination of physical parameters of transition from deflagration to detonation and gaining sensitivity to the initiating pulse from the detonator cap by the ordinary explosive compositions.
Keywords: Arctic zone, seasonally freezing soils, permafrost, frozen crust, granulites, ordinary explosives, compound stability, deflagration, water-blocking additive, detonation, booster
