MODEL OF FORMATION OF DUST AND GASES IN THE EXPLOSION CHAMBER OF THE BLASTHOLE CHARGE IN SULPHUR-CONTAINING ORE

Abstract

The ragging processes of sulphide ore and its oxidation in the explosion chamber during the detonating of an explosive charge were considered. The theoretical model of the processes of formation of dust and gases that take place in the explosion chamber was built taking into account the regularities of chemical and phase equilibriums at high temperatures according to the universal thermodynamic method of determination of equilibrium characteristics of random heterogeneous systems based upon the fundamental principle of entropy maximum. The model was based upon the system of famous laws and equations: V.L. Kirpichev’s law, logarithmic normal distribution, the equation of energy balance, diffusion law, and the principle of entropy maximum. The results of the calculations of parameters of gas formation and inhibition were obtained. Much attention was paid to the distinguishing of the regularities of formation of sulphur dioxide gas at oxidation of the finely divided sulphide dust. The efficient inhibitive additives were determined. Jr. of Industrial Pollution Control 33(1)(2017) pp 804-808 www.icontrolpollution.com Review *Corresponding
