INFLUENCE OF MECHANICAL ACTION AND CRYOGENIC CONDITIONS ON THE PHYSICO - CHEMICAL CHARACTERISTICS OF THE ROCKS

Abstract

A change in the internal structure of the rock under the effect of the mechanical and cryogenic action is examined. Three experimental studies with the granite models of the rocks were carried out. The first experiment showed that the mechanical action change the crystal structure of granite, and the second experiment completely converges with the theory, and it shows that the rocks are destroyed more rapidly under the influence with the higher speed, than with a constant or smoothly risen load. In the third experiment the models of granite were submerged in liquid nitrogen (77,4 K) and liquid helium (4,2 K).
