The impact of blasting on the environment in the open pit mining

Abstract

In the open pit mining of mineral raw materials, blasting, whose role is to break the undisturbed mass for easier loading, is the necessary technological phase. In the mass blasting at the open pits of metal ore, there is a rise of cloud composed of gases and dust, blasting mining products, which have negative effects on the surrounding environment. This work presents the calculations of a cloud size, concentration of gases and dust in blasting.
