Numerical simulation of disaster effects induced by typical industrial explosive explosion
Abstract：In order to evaluate the disaster effects generated by accidental explosion in air for typical industrial explosives,the spreading characteristics of air shock waves and temperature field of free-field explosion for 1kg ANFO,emulsion explosives and the 2nd rock explosives are investigated based on the nonlinear dynamics software AUTODYN and JWL state equation of explosion products,and are compared with TNT explosives.The calculated results show that in the temperature damage effect,the highest temperature is generated by rock explosives;the second is ANFO,followed by emulsion explosives.That disaster effect of temperature,the highest temperature is generated by the 2nd rock explosives and the second is ANFO,followed by the lowest temperature peak emulsion explosive.These conclusions provide theoretical basis for the correct use of industrial explosives and the safety of mines.
