Assessment of the state of the soil cover on the territory of the goldcopper-porphyry deposit for the design of the mining complex

One of the problems in performing engineering and environmental surveys is conducting soil studies within the boundaries of deposits and promising ore occurrences to determine soil fertility, assess their sanitary and epidemiological condition. The urgency of the problem is determined by the requirements of environmental legislation for the rational development of natural resources and the need to preserve the fertile soil layer. Conducting soil research is mandatory and is fixed in a number of regulatory documents regulating the conduct of engineering and environmental surveys. Standard methods of obtaining information were used during the study of the soil condition: field examination, laboratory tests and in-house processing of the data obtained. The results of agrochemical and geochemical testing of the soils of the studied territory were obtained, the depth of the humus layer of soils was determined, a schematic soil map was compiled, which became the basis for making recommendations for removing the soil cover. It was recommended that when carrying out earthworks, a removal rate up to a depth of 0.4 m should be provided for all types of soils, and used without restriction during reclamation, and for areas of development of sod-taiga soils, further use is possible after mixing in storage areas to improve the chemical properties of rocks. Background concentrations of heavy elements in the soils of the territory were also determined, which are characterized by excess content of arsenic, copper and zinc elements, which is explained by the fact that the studied territory is confined to an area with the presence of ore mineralized zones that form a regional natural background.
