Calculation of the stress-strain state in jointed rock around mine workings
- 25 Downloads
A method is devised for calculating the stress-strain state in jointed rock; it yields the necessary information concerning the character and magnitude of the elasticoplastic deformations of the rock near the perimeter of mine workings.
Contact movements exceeding the critical deformations indicate loss of stability of the rock. In the case of appreciable (subcritical) disruption of the structure of the rock by load relief processes, the rock cannot be regarded as a continuous medium, and thus we cannot make use of engineering methods developed for rock as a continuous medium.
