Abstract
Sulfide dust explosions and hazardous sulfur gas emissions are still an urgent problem in blasting operations at copper deposits. In this paper, the solution to this problem is proposed by using an optimized explosive structure. Theoretical analysis of the main characteristics of explosive transformation of the proposed structures depending on the physical and chemical properties and the content of safety additives in the explosive is carried out. The obtained graphical dependences allow a differentiated approach to the choice of the explosive structure, providing effective explosion performance and proper safety of blasting operations.
