Аннотация: Perm region is an old mining region. Mining has been underway for more than 300 years. Potash salts and coal were the main types of exploitable mineral deposits in the twentieth century. Coal deposits are located in the Pre-Urals, geologically confined to the West-Urals folding zone. The high prevalence оf karst rocks is typical for this area. Deposits of the Kizel coal basin are the subject of study. These deposits were developed from the end of the 19th to the beginning of the 2000s. High water inflows were common - total drainage reached 10-12 thousand m3 /hour. The mines have been flooded since the beginning of the 90s of the last century, by now all the mines have been flooded, 16 springs of mine waters have been formed. High discharge rates - up to 1000 m3 /hour during snow melting arc typical for these springs, the total average annual flow rate of springs of mine waters is more than m3 /hour. The waters of the mine water springs are sulphate high-metal with low pH. These springs for tens of kilometers pollute the rivers ol the Kama basin, the Volga tributary. Attempts are being made to reduce the environmental damage caused by the spouting of mine waters since the early 2000-s.
