Abstract
The article presents the results of investigations of the influence of stress state form, cyclic loading and time of bearing specimens under loads on the pattern of changes in porosity and permeability. It was stated that compressibility of rocks is proportional to porosity, and with rise of applied stress the compressibility decreases exponentially.
