Abstract

Abstract—Mass industrial explosions on extended benches of open pits are the most effective way to crush rock. Such explosions are accompanied by the rise of a gas and dust cloud. Three-dimensional numerical experiments are used to study the interaction of ascending gas and dust clouds generated by three, five, and multiple linearly arranged explosions in open pit mines. We examine both the initial stage of formation of a hot rarefied dust and gas cloud after the scattering of detonation products and the subsequent rise of thermals caused by buoyancy forces. We have obtained the dependences of the rise altitude and the size of the gas and dust clouds on the distance between adjacent explosions.
