On the possibility of applying the theory of elasticity to solving problems of deformations and stresses in rocks surrounding the excavation

Abstract

The quantitative determination of the magnitude of deformations of rocks of various kinds in mine workings and the magnitude of rock pressure in the workings associated with these deformations raises the question of the fundamental possibility of applying to the solution of these problems the principles of the theory of elasticity and the theory of resistance of materials arising from the latter. It is very important to correctly solve the problem of rock pressure and rock deformation, since they essentially cover the entire complex of issues that is called rock pressure management (roof management) and which is the main and decisive factor in the correct conduct of mining operations. As a result of this circumstance, there is an urgent need to consider the possibility of applying the theory of elasticity to solving rock pressure control problems in more detail and to clarify the fundamental possibility (or impossibility) of such an application.
