Opis:: 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.

Opis:: The Jones-Wilkins-Lee (JWL) equation of state parameters for ANFO and emulsion-type explosives have been obtained from cylinder test expansion measurements. The calculation method comprises a new radial expansion function, with a non-zero initial velocity at the onset of the expansion in order to comply with a positive Gurney energy at unit relative volume, as the isentropic expansion from the CJ state predicts. The equations reflecting the CJ state conditions and the measured expansion energy were solved for the JWL parameters by a non-linear least squares scheme. The JWL parameters of thirteen ANFO and emulsion type explosives have been determined in this way from their cylinder test expansion data. The results were evaluated through numerical modelling of the tests with the LS-DYNA hydrocode; the expansion histories from the modelling were compared with the measured ones, and excellent agreement was found.
