Stress State of Support System in Temporary Roadway in Unstable Rock Mass
The authors estimate stress state in the support system and in rocks nearby a roadway driven in unstable rock mass and when the voids and cavities in the roadway roof are filled with hardening foam. The calcul...

Stress state of rocks surrounding excavations under variable Young’s modulus
Deep-level mining needs extra data on physical behavior of rocks at great depths (under high stresses). Without such data, any computations for deep-level technologies based on analogy with shallowdepth techno...

Accounting for depth-wise linear change of stresses in the intact rock mass in geomechanical problems
The authors discuss formulation of boundary conditions in problems on stress-strain state of rocks around an underground excavation. The classical formulations neglect the presupposition of linearity of stress...

Mathematical modeling of rock specimen deformation
Among the aspects of modeling mathematically deformation of rock specimens, the article analyzes soft and stiff loading. The authors formulate an inverse problem on identification of mechanical properties, bou...

Damage accumulation in a piecewise-homogeneous rock block under compression
The damage accumulation in a rock mass is conventionally monitored using rock specimens that are subjected to gradually growing compression for acoustic emission recording. The research problem is to establish...

Identification of weakenings in a rock block
The authors propose a process for identification of a weakening location in a rock block and the algorithm of its numerical realization based on the direct problem solutions and complementary data on boundary ...
