More than half of solid minerals are extracted in Russia by open pit mining. The development of large deposits is usually carried out by quarries of considerable depth, which is constantly increasing. Increasing the depth of quarries, as a rule, contributes to the deterioration of working conditions and atmospheric air pollution both in and around the quarries.
