Abstract
The rock in a rock mass is in a tense equilibrium. This equilibrium is usually broken when mining operations are stopped. There are many theories related to rock pressure in the stoping zone. Obviously, the solution of problems on this subject is associated with the study of deformation and dislocation processes of rocks in the workings and mine shaft. Since it is difficult to conduct grandiose full-scale experiments, these problems have to be solved by new developed methods, which are very universal and informative.
