According to the results of a number of studies, a negative impact on the water and air environment of natural runoff exposed to man-made activities has been identified. Due to this influence, it is necessary to differentiate the types of water taken from these drains. The object of study is the mine water Novoshirokinskoe of the mine, and the subject is their horizontal geochemical typification.
The chemical macro- and microcomponent composition of mine waters, selected from different horizons, is investigated. The chemical composition is influenced by: the initial composition of groundwater, which is formed from the source of underground water, precipitation and surface sources of nearby water bodies; Mixing groundwater with different horizons and their relationship with dissimilar rocks and ores that can be used in the development and operation of this deposit.
Through data analysis, five hydrochemical types of groundwater were identified: bicarbonate-sulphate calcium-magnesium; magnesium sulfate-bicarbonate; magnesium bicarbonate; sodium bicarbonate; bicarbonate magnesium-calcium. It has been established that on underground horizons up to +850 m water is represented by bicarbonate-sulphate calcium-magnesium and sulphate-bicarbonate magnesium types. At the + 800 m horizon, magnesium bicarbonate is formed at the level of +750 m and magnesium-calcium bicarbonate at the +650 m horizon. With the decrease of marks there is an increase in the level of iron, manganese, muscle, zinc, aluminum and chromium. An excess of the content of some chemical components in them, which are water bodies of drinking and fishery significance, was found. Contaminated waters vary in degree of contamination. Such excesses are associated with the influence of ores and host rocks. Another reason is blasting |
