Determination of the dimensions of the inelastic deformation zone around a supported opening subjected to abutment pressure
Authors:
Abstract
The magnitude of rock falls, the load on mine support, and the displacement of their contours are determined mainly by the extent of the inelastic deformation zone formed in the rock mass surrounding the workings. In the practice of maintenance, the majority of development workings are affected by abutment pressure, and there are no calculation methods for assessing this effect on the size of the inelastic deformation zone.
