Abstract

 Deep deposit extractions require research in new technologies of mineral resource search and exploitation. Thermal contact less methods give good opportunity to drill relatively great depths. According to findings of theoretical and practical studies, radial fractures evolve in thermally strained rock environ. Therefore, for the new drilling method research, it is necessary to study both drilled rock and resulting melt in detail. This paper deals with rock melt and its possible penetration into fractures formed during drilling process. Simultaneous recording of TG and DTA using thermoanalyzer SETARAM TGTDA92 was made to determine phase transitions and rock melting temperatures. Using ANSYS13 software, it was possible to create CAD model and to determine the behavior of melted rock and rock melt. The results of the study are meant for their practical use during the vertical drilling processes.
