    Realization of boreholes for heat pumps in the area of the University Hall and the Centre of Innovational Technologies (CIT) VŠB Technical University of Ostrava
    (2008) Klempa, Martin; Mazáč, Josef
    Down the hole hammers seem to be the best instruments for drilling the boreholes for heat pumps. Heat pumps use renewable energy sources to supply heat for homes or industrial buildings and to heat service water. Boreholes for neat pumps are unrecoverable products. Therefore they have to be drilled in high quality. Basic information about down the hole drilling is given in this paper. Attention is paid to disintegration of rocks using down the hole hammers, their construction, basic technical characteristics, drilling equipment and also ensuring the optimum conditions for effective operation of the down the hole hammers. In the end, the areas of their application with the concrete case of drilling in the area of Aula + CIT VSB - Technical University of Ostrava are presented.
