ABSTRACT
Conventional geomechanics bases on principles of the classical theory of continuum mechanics. However, new experimental results such as zonal disintegration around deep openings and reversible deformations of highly stressed rock samples cannot be described accurately in its terms. A new approach to geomechanical mathematical models involves non-Euclidian modelling to describe abnormal experimental findings. As a result, a new concept of the theory of geomechanics, i.e. geomechanics of highly compressed rock and rock mass is developed that improves considerably prediction of geomechanical phenomena. This paper describes principles of highly compressed rock and rock mass geomechanics. The use of non-Euclidian modelling is demonstrated at two hierarchical levels of block geomedium, i.e. a rock sample and rock mass around the openings.
