Abstract

The work is focused on the problems of crystal lattices of chlorite-slates and quartzite's by the methods of X-ray diffraction thermal gravimetric analysis when rocks were exposed to the air plasma within the temperatures ranged from 2000 to 3000 °K within the bounds of technological process of widening the boreholes. The analysis of physical-chemical parameters of rocks crystal lattices exposed to the irradiation of plasma conducted within the frames of non-equilibrium thermodynamics has showed the concordance of the Le-Chetelier principle about the displacement of the thermodynamic system to the direction of the effect at the thermal exposure, one form of which being the transformation of the rocks crystal lattices and consequently an increase of activation energy, a thermal breaking of rocks during their plasma heating process.
