New possibilities and perspectives of building hotwater line from geothermal wells heat exchanger to TEKO Košice

Thank to favourable geological conditions, Slovakia is a country abundant in the occurrence of low-enthalpy sources. The government of the state sponsors new renewable of the sources ecological energy,including the geothermal energy. Geothermal water is utilized for recreation (swimming pools, spas), agriculture (heating of greenhouses, fishing) and heating of houses. The effectivity of utilisation is about 30 % due to its seasonal use. That is why the annual house-heating and the hot water supply from geothermal sources are supported. Recently, the company Slovgeoterm has initiated heating of greenhouses in Podhajska and hospital and 1231 flats in the town Galanta. Nowadays, a research for the biggest geothermal project in the Middle Europe – construction in Košice basin has started

Energetic dependency on the oil reserve- resources of crude oil in the world

Crude oil belongs to the most important energy resources nowadays., However its reserves are the smallest in comparison with other energy resources as coal, gas or uranium. The world oil consumption continuously increases and within 20-year period there could be about one third. So, the consumption of combustibles will probably increase and the reserves will decrease. Promising are new resources or a better utilization of primary sources. It´s a question of a short time when world scientists should think about this indisputably worldwide problem and would provide an equivalent substitution with an available ecological solution

Possibility of Radioactive and Toxic WasteDisposal in a Rock Ssalt Deposits in Slovakia Combining Wells and Cavities

Disposal of radioactive and toxic waste in rock salt can be performed in two ways disposal in the salt mine repository or disposal in the deep wells connected with salt cavity. Presented article deals with the option of the disposal in a salt cavity at medium depths. The article also cover partially salt deposits in Slovakia and their potential suitability for waste disposal.

Realization of Borehol V1 Till V4 at Liquidation of Shaft Leopold Situated in the Solivar Part of the Town of Presov

Leopold shaft is situated in the Solivar part of the town of Presov, object (object of National Cultural Monument Gapla). Strong ascent of the level of natural salt brine resulted in the change of stress state of rock massif with subsequent deformation of shaft reinforcement and endangering stability of its surroundings and possibly affecting the surface. After the thorough evaluation of the findings the mining complex was to be liquidated. The shaft liquidation will consist of the system of independent, yet indivisible measures that will ensure long-term safety of the surface surrounding the Leopold shaft
