Natural And Mine Waters Of Verkhnekamskoe Salt Deposit

The characteristic of suprasalt waters, natural and man-made brines of the Upper Kama deposit of potassium and magnesium salts is given. A classification and a set of diagrams allowing to diagnose the nature of newly identified brines are proposed. For over-salt waters, a change in composition with depth is shown, and for salt brines, an interconnection with the lithological composition. Two main trends in the evolution of brine and emergency waters are identified. They are caused by the formation of brines in the roof of the salt layer subject to varying degrees of erosion by the processes of underground leaching. It is noted that the composition of condensate waters formed by mine workings during the years depends on the lithological composition of the host rocks and is due not to direct dissolution, but to selective leaching.
