“…The eolian dust of the open beaches and tailings dam yields about 100 tons of inorganic dust with an amount of SiO 2 from 70 to 20% per year, which leads to the formation of an atmochemical halo of an area of 16 km 2 . A significant proportion of dust in the atmospheric surface layer settles on the high-value forest landscapes [Conner & Hoeffner, 1998;Pashkevich & Petrova, 2017].…”

The Lomonosov diamond mine is located in the Primorsky district of the Arkhangelsk region, 100 km northeast from the Arkhangelsk and is represented by six kimberlite pipes: Pomorskaya, Arkhangelskaya, Karpinsky-1, Karpinsky-2, Pionerskaya, and Lomonosov. Ore mining has been carried out since 2005 on the Arkhangelskaya pipe located in the southern part of the deposit. The Arkhangelskaya pipe is composed of tuffites, tuffaceous sandstones, breccias of sedimentary rocks, and sandstones. The kimberlite mineral composition is characterized by clay minerals pseudomorph after olivine.

“…The negative environmental impact of mining enterprises raises annually (Bwapwa et al, 2017;Pashkevich, Petrova, 2017;Simate, Ndlovu, 2014). This is due to an objectively increased consumption of material resources by mankind (Alekseenko et al, 2017a;Beloglazov et al, 2014;Cehlár et al, 2016;Gumenik et al, 1988;Pashkevich, 2017).…”

The paper provides an assessment of the potential technogenic impact of sulphidecontaining wastes produced by ore extraction and processing at the Ozernoe deposit, which is currently at the initial stage of mining. The analysed averaged samples of ore and wastes of mining and processing were obtained in the course of semi-industrial experimental preproduction. The results of monitoring studies in the area of sulphidecontaining dumps formed at an exploring mine in the 1960s were used for assessing a potential hazard of the wastes. The origin of acid mine drainage is described. Advantages and shortcomings of tests assessing acid mine drainage are considered. The used express-method of acid indication allows to reliably determine the risk of acid mine drainage by the values of acidic and neutralising potentials formed by rocks. An estimation of acid mine drainage formation and heavy metal migration is carried out at dumps of the exploring mine. The forecast of environmental impact is given for the future wastes of mining and processing at the Ozernoe deposit.

Insulation methods, helping to prevent the negative environmental impact of mine dumps, tailings and other waste storages, are considered and their drawbacks are revealed. The proposed two ways of environmentally sound and cost-effective preserving are described. The first approach is to form polymeric screens over the waste surface, as well as under a storage facility. The conducted experiments included the investigation of changes in physical and mechanical properties of polymers depending on their processing temperature. To study the suitability of low-density polyethylene, high-density polyethylene and polypropylene, the damage to the coating structure integrity as a result of normal load application is assessed. The second approach is to cover slopes of the dumps with a three-dimensional erosion control mat. The subsequent hydroseeding allows ensuring complete coverage and high strength of the slope surface in a short time and at the lowest cost. In order to prevent mine dump erosion and minimise associated costs, the analysis of key properties was performed. It was revealed that polypropylene and polyester used as a geonet are characterised by the lowest volume of fertile soil needed to cover.
