Determination of the dimensions of the inelastic deformation area around a fixed excavation subjected to support pressure
Authors:
Abstract
The magnitude of rock outcrops, the load on the support of mine workings, and the displacement of their contours are determined mainly by the size of the inelastic deformation area formed in the rock mass surrounding the workings. In the practice of maintenance, the majority of preparatory mine workings are influenced by the support pressure, and there are no calculated methods for assessing this effect on the size of the area of inelastic deformations.
