Investigation of the gas-dynamic processes in the operation of an explosion-reactive complex

Abstract

Abstract To conduct drilling and blasting operations in difficult climatic and geological conditions at mining enterprises, it is promising to use explosion-reactive complexes (ERC). Having a clear advantage, these devices have a number of disadvantages, mainly due to the gas-dynamic instability of the process of their functioning. A non-stationary gas-dynamic model of the development of such processes at different stages of ERC operation was developed and analyzed. The analysis was performed by methods of numerical mathematical modelling. The simulation results allowed the authors to further justify the rational parameters of the installation and its individual components, which significantly increased its efficiency.
