Abstract


PROGNOSIS OF WATER SYSTEM CHANGES IN THE VICINITY OF PLANNED EXPLOITATION OF SULPHUR DEPOSITS SITUATED UNDER THE OSIECKIE LAKE NEAR TARNOBRZEG

Abstract. The hydrogeological model along with prognostic calculations allowed for presenting the prognosis of water condition changes within the Quaternary multiaquifer formation as a result of planned exploitation of the sulphur deposit situated under the Osieckie Lake. Sulphur extraction with use of underground melting will become possible after changing the way of deposit dewatering. It includes lake partition with the earth weir, water pumping out from the southern part of the lake and the creation of several mining sumps. Their total discharge of ca. 5000 m3/d will assure required depression of the groundwater table also under the conditions of land subsidence. In the northern part of the lake, the current environmental conditions will be retained. However, a supply of uncontaminated surface water with the rate of 1400 m3/d will be required.
