Abstract:
Deformations and damages around workings and drill holes are usually zonal. They appear when strain in masses at great depth become recurrent and macro defects result in the areas, where principle compression tangential stresses take place causing a radial compression in the intermediate zones. The article presents a mathematical model of highly compressed rocks based on the principles of non-Euclidian mechanics and nonequilibrium thermodynamics as well as the methods of determining the parametres of the model. A satisfactory conformity between the results of the theoretical and experimental investigations has been obtained. The dependence of the principle structural parametres of the model on the affecting factors has been established as well.
