Objective. For the purposes of scientific research, by definition, basic properties and characteristics of explosives, explosion parameters and its impact on the environment the laboratory of destruction of rocks mining Institute UB RAS purchased the device "DATATRAP II" which allows determining the speed and duration of detonation, detonation pressure when testing powder, granular and emulsion explosives. The purpose given in the article results of the research was the testing of this measuring equipment at the test site, and in the technological wells. Methods. For this purpose we used a comprehensive method of research involving the synthesis and analysis of scientific literature and conducting experiments. Results. On the basis of instrumental measurements of velocity of detonation held to blow up the blocks in the technology well and field tests in mines of JSC "EVRAZ KGOK", OJSC "Uralasbest" in the quarries "Sibay", "Autumn", "Sibayskiy limestone", "Anniversary", "Orenburg minerals", "Khaibulinsky" and "left Bank" approved methods for determination of basic characteristics of emulsion explosives. Conclusion. The conducted instrumental measurements using a measuring equipment "DATATRAP II" with the aim of determining the detonation characteristics of emulsion explosives "Fortis" brand name "Eclipse" and "Advantage", "Nitronit" brands "of e-70 and e-100" during the instrumental measurements in technological blasting wells in mass explosions, in vertical and horizontal cylindrical charges of high EXPLOSIVES in field tests, and for determining the actual intervals of delay between the boreholes allowed us to obtain more accurate and additional measurements of the basic properties of EXPLOSIVES. Tested EE allowed us to determine the magnitude of velocity of detonation not only in field tests of individual charges, but also in several technological blasting wells with multi-channel parallel connection of the probe cable into the wells and simultaneous measurement of the actual interval of delay between the boreholes. The obtained experimental data allow to determine the compliance of explosives to quality control standards, specifications and to optimize the rational parameters of drilling and blasting operations.
