Abstract

The current stage of blasting operations in Russia is characterized by a high rate of development and production of new types explosives and initiating devices. In this context improving the technology of mass explosions in the quarries is an important task. The idea of the work is improving the energy efficiency of explosives and achieves the required quality of rock crushing. Increased explosive fragmentation of rock can be achieved by increasing the fugacity and brisance provided a rational volume concentration of energy in the rock mass explosion. To implement the necessary quality rock crushing author proposed to use explosives based on ammonium nitrate using turbulence promoter and modernized packaging explosive of cartridges. However, to achieve the most efficient technology of blasting is an urgent question of constructing storage of explosive materials. In view of this, the authors developed a model project of powder storage with its feasibility study.
