Abstract
The deterioration of the ecological state of the environment and health of the population living in developing Carpathians deposits of potassium, determines the need to study environmental hazards and risks. The problem of exploration and construction a significant land area is of importance in the conditions of modern society development. Great competition, high density of buildings and insufficient volume of land fund resulted in the use of structurally unstable soils under construction. In the industrial area of Kalush, Ivano-Frankivsk region, large area is occupied by saline soils, which belong to the district of development of Kalush-Holynska potassium salts deposits. The ineffective conservation of mines led to the formation of ground dips and destruction of civil and industrial buildings. The problem of insurance of civil and industrial buildings destruction currently is one of the major. While designing buildings, which are located in the area of the mine workings harmful impact, the State building standards of Ukraine and international standards must be taken into account. Study of foreign experience enables prediction of stability of buildings foundations constructed on saline areas. The presence of different quantitative composition of salts in soils affects the deformation parameters of soils. When saline soils are moistening the dissolution and removal of salts which they contain occurs, and accordingly the soil porosity increases. According to the results of calculations dependences between the concentration of salts in the liquid have been received and the specific amount of salt on the thickness of the soil with time in cases of disperse and pellicle salinity. Kinetic curves of suffosion subsidence to disperse and pellicle types salinity were built, the use of which will allow to predict and control subsidence of technologically loaded areas saline soils.
