Abstract
The conducted investigations allowed to establish the regularities of changes in mechanical properties of rocks with due account of influence of the stress state type, forms and kinds of moisture in rocks. Condition of the final state may be regarded as the criterion of rock failure depending on the moisture content, value of pore pressure and stress state type under constant velocity of deformation.
