“…The 3rd International Electronic Conference on Geosciences, 7 -13 December 2020 forest) is cut. In addition, the operation of the largest diamond-bearing pipes is complicated by the arrival of brines from subpermafrost high-pressure water-bearing horizons, their safe disposal in underground storage is a cornerstone of ensuring a favorable environmental situation [3]. Rock elevated from the depths, accumulate in the overburden rock dumps with a height of approximately 100 meters, and enrichment products are stored in extensive tailing dumps.…”

Geochemical risk is caused by the release of hazardous chemicals to the earth surface. Primary diamond deposits are located in difficult mining and geological conditions. They represent natural geochemical anomalies associated with the mineral composition of rocks and groundwater, which contain a number of impurity elements with high toxic properties (Tl, Di, As, Cd, Hg), increased concentrations of heavy metals (Cu, Zn, Pb, Ti, V and others). The paper presents the physical-geographical and mining-geological conditions of the diamondiferous region, where three large mining and processing divisions operate: Udachninsky, Aikhalsky and Nyurbinsky. pH, organic matter (humus), total nitrogen, physical clay were identified in the study samples, by using potentiometric, photoelectric colorimetric, spectrophotometric methods and pipette method for particle size analysis. Gross and mobile forms of trace elements were determined by atomic absorption and emission spectrometry. The groups of elements were identified, that determined the natural and man-made anomalies. The accumulation of Cr, Ni and Co determines the influence of kimberlite magmatism in general. Cu, Sr and Li are accumulated in the soils of the Daldyn-Alakit diamond-bearing region. Increased concentrations of Mn and Cu are typical in the soils of the Sredne-Markhinsky diamond-bearing region. An assessment of the ecological and geochemical state of the study areas was carried out according to the indicator of total pollution (Zc), which is the sum of the excess of the concentration coefficients of chemical elements accumulating in anomalies. Areas of pollution and zones of the greatest risk are localized, which occupy up to 75% of the total area of industrial sites. They confined to quarry-dump complexes and to areas of impact of tailing dumps of processing plants.

“…The scope of the school embraces two trends: the analysis of open pit mining data of metallic (nonmetallic) and coal deposits and the long-term monitoring of initiation and evolution of vegetative ecosystems in the areas of depleted and operating open pit mines and overburden dumps. Environmental professionals in mining are always faced with the same problems and solutions presented on a selective basis in [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

The paper presents study results of the disturbed lands ecological state due to the opencast mining of deposits of non-ferrous metal ores in the Murmansk, Arkhangelsk and Krasnoyarsk regions. According to the OMS data on quarries, rock-disposal dumps, processed ore storages' surface there have been detected some self-restoring vegetation ecosystems. The necessity in rehabilitation of rock-disposal dumps piled during mining operations in areas with a short vegetative cycle has been substantiated.
