Hydrogeological and geothermal changes in karstic reservoirs due to mine dewatering
Lowering of the piezometric-head due to pumping to protect mines from water-inrushes can create an extensive cone of depression. As a result of this, the directions of ground water flow in the surrounding aquifers can be changed, which can be sensitively indicated by the changes in water-temperature. In the bauxite deposits of Hungary the regular temperature measurements in the piezometric boreholes and observation wells, makes it possible to monitor, in combination with other methods, the hydrological structure of the surrounding rock mass.
