In this workcylinder testswere performed for two emulsion explosives (Emulinit 8L and Emulinit GM1) used in the mining industry. Based on the results of the tests, the detonation pressure and energy of these explosives were estimated. The detonation characteristics obtained, the profile of the expanding copper tube and the results of the numerical simulation enabled the constants in the JWL(Jones-Wilkins-Lee) equation of state to be determine for the detonation products of these two explosives.
