Petrikov deposit of potash salt is situated in Gomel oblast of Belarus in the south-east of Pripyat Trough, and consists of Northern and Southern prospects. Underground mining of potash salt will start at the Northern prospect with the area of 166 km2. It is expected that mining will last for about 50-80 years. Environmental Impact Assessment (EIA) was carried out at the stage of designing of Petrikov mining and processing plant. Standard EIA procedure included a set of investigations, including assessment of surface subsidence, assessment of changes in groundwater level, assessment of changes in productivity of forest phytocenoses and crops, and assessment of groundwater pollution due to production of potash fertilizers. Maximum values of possible surface subsidence (up to 2.3 m) will occur within the area, where the surface will be effected by mining of potash layers 1, 2, and 3 of the productive horizon IV-p, using long-pillar mining system. Surface subsidence will influence surface topography, surface and groundwater, landscape structure and land resources. The result of surface subsidence will lead to inundation and swamping of land, as well as to increase in the areas affected by annual floods in the valleys of Pripyat and Bobrik rivers. Surface subsidence will affect the whole area of the prospect within the limits of planned mining fields, except the areas above safety pillars. In the result of raise in groundwater level the area with groundwater depth of more than 2 m will decrease from 69.1% to 17.8%, and the areas with groundwater depth from 3 to 5 m will disappear. The area with groundwater depth less than 1 m will increase from 0.1 % to 34.0 %. Within 19.5% of the area the groundwater level will raise above the surface level (the area of inundation). Surface subsidence and change in groundwater level will cause certain decrease in yields of timber and crops, besides this 25.64 km2 of forest, 0.68 km2 of arable land and 3.24 km2 of meadows will be inundated. In order to prevent inundation within certain areas the protective engineering facilities have been designed, and arrangement of groundwater monitoring wells has been proposed. The protective facilities at solid and liquid sludge dumps are designed to prevent the environment from pollution. Nevertheless, the patterns of possible migration of pollutants in groundwater were assessed in case of accidental discharge of waste.
