Abstract:
Full-scale experimental study of the rock spallation by means of plasma jets is carried out. The aim of the experimental study was the measurement of the thermal power of plasma, weight of the rock spalls and duration of the plasma jets influence on the borehole surface. For the weight measurement of the rock spalls VT-200 analytical balance was used. In experimental study plasma jets flow out directly into the borehole of the granite block. The borehole and nozzles parameters of the plasmatron are complied with geometrical similarity. Experimental data are processed in the form of the energy consumption dependence of the thermal reaming of the borehole from the duration of the thermal treatment of the borehole surface. The results of the study could be applied to the borehole drilling processes.
