Astakhov, S. Khazov, D. Shirochin, L. Ékonomova] Conclusions: 1. A sign of the physicochemical softening of coal occurring as a result of its saturation with carbon dioxide under conditions of T≤Tcr(CO2) and P≥Pc characterizes a quite substantial antibatic change in the measured electric resistance and capacitance of coal caused by condensation of carbon dioxide in coal. As a result, the ultimate strength of the specimens decreases by factors of 5-10 and more, right up to complete dispersion. 2. The value of the pressure of capillary condensaton Pc depends on the structure of coal, its moisture content, and on the number of cycles of occurrence of condensate of the sorbate. The pressure of capillary condensation decreases from cycle to cycle and accordingly the value of the maximum measured resistance changes. The quantity of the characteristic fraction increases with increase of the number of cycles; the quantity of the coarsest fraction practically decreases to zero during 3-4 cycles. 3. Irregular fluctuations of the electrophysical parameters occurring under conditions in which carbon dioxide condenses in the porous structure of coal are also a characteristic sign of destruction of the porous structure of coal by carbon dioxide condensate.
