Influence of rock disturbance on their rheological properties
Complex investigations have been conducted of rheological properties of undisturbed and disturbed rocks under laboratory conditions in the modes of creeping, relaxation and lateral pressure. It was stated that the rheological properties of disturbed rocks substantially differ from those properties of undisturbed rocks. Recommendations are given for the use of the obtained results in solution of tasks in mining geomechanics.

Lateral earth pressure in rock mass
- Authors:
- A. G. Olovyanny
The stress state of rock mass is determined by weight of overburden and the lateral earth pressure. It was stated that the stress state of rock mass has been originated with contribution of the lateral earth pressure in which the important role play the viscoelastic properties of rocks was obtained, which gives more precise assessments of stress state in rock mass than the determined ones with account of only elastic behavior.
