Abstract
In the process of developing a mineral deposit into the open pit atmosphere, dust and toxic gases are emitted from a number of sources. The intensity of such emissions depends on the properties and condition of the rock, weather conditions, engineering and development technology, the effectiveness of the application of methods for suppressing dust and harmful gases. In this regard, dust and gas contamination in the workplace can vary widely and have a negative impact on humans and the environment. The aim of the work is to analyze the processes of dust formation during blasting operations at the quarry of the mining and integrated works (for example, OAO Mikhailovsky in the city of Zheleznogorsk, Kursk Region). During mass explosions at the quarry of the mining and integrated works, the sources of dust and gas emissions were investigated, and a qualitative and quantitative assessment of their components was given.
