Summary The open-pit method for developing mineral deposits is one of the leading methods for obtaining ore and non-metallic raw materials. Its use in mining contributes to the activation of various processes that transform the geological environment, often causing irreversible changes in the properties and characteristics of all its components. The object of the study of the transformation of the geological environment was a Deposit of ore and placer gold, located in the Bodaybinsky district in the East of the Irkutsk region. The study of ground and hydrogeological conditions during drilling and mining operations in conjunction with analytical studies and instrumental observations allowed us to obtain quantitative characteristics of the parameters of the ground layers formed in the landscapes of placer deposits during repeated mining. On the basis of generalization of research results identified the main factors shaping the modern state of the geological environment on the territory of the gold deposits, the character and the degree of transformation of geological environment as a result of years of alluvial gold mining before the industrial mining pit method. |
