MONITORING OF THE ECOLOGICAL STATUS OF THE TERRITORIES OF DEVELOPMENT OF POTASSIUM SALT DEPOSITS AND ESTABLISHING THE METOD FOR MINIMIZING ECOLOGICAL RISKS

The analysis of data concerning the composition of highly minaralized salt brines of potassium deposits within the Precarpathian (in particular, Kalush-Holyn deposit) is carried out; the methods of salt brines disposal is analyzed. It is revealed that traditional approaches to salt brines destruction cannot be considered environmentally acceptable; the only reliable way of the disposal of highly minaralized salt brines is landfilling in depleted hydrocarbon reservoirs nearby. Based on conducted researches, it has been found that the suggested method of disposal of salt brines in depleted hydrocarbon reservoirs is environmentally friendly and ensure the safety of high-mineralized salt brines landfilling for the long-term prospect.
