Please cite as: CHEMIK 2014, 68, 1, 9–16 This paper presents the results of saletrole cylindrical explosive charge detonation in the air, using Ansys LS-Dyna program. Results of numerical analyzes were referenced to the actual effects of detonation in proving ground researches. Simulation and experimental researches were performed for cylindrical charges having a diameter 45 mm and length 250 mm. Additionally the measurements of the blast wave intensity were conducted by using Held’s Method, and measurements of the blast wave overpressure in three characteristic directions relative to the charge are also discussed. Keywords: blast wave, ANFO, computer simulation, impulse density
