Abstract: The input control of explosive materials and the measurement of the detonation rate of the charge are important in the production of explosive work. The detonation rate of the explosive charge, as one of its most important characteristics affecting the quality of the explosion, depends on many factors, the main of which are: the quality of preparation of explosives and their components. Incorrectly selected parameters of drilling and blasting operations and poor quality of preparation of explosives lead to a decrease in the detonation rate up to detonation failures. In turn, detonation failures lead to an increase in material costs and an increase in the risk of negative events related to safety when handling explosive materials. The correct approach to preliminary quality control with the use of appropriate measurements will improve the efficiency and safety of preparing the rock mass for excavation by drilling and blasting. The article presents a technique for measuring the detonation velocity of a borehole charge with the corresponding results and conclusions, allowing timely measures to be taken to maintain the detonation velocity of explosives at the required level.

Keywords: measuring the detonation rate of an explosive charge, parameters of drilling and blasting operations, surfactants, pulse reflectometry
