Current problems and objectives in geomechanics

The authors discuss one of the key objectives of geomechanics as a mining science. It consists on the investigation of deformation processes phenomena in rock mass and ground surface toward safe and efficient subsoil management as a type of economic activity, as well as for safe and sustainable operation of permanent underground and surface facilities of subsoil use. The emphasis is laid on the fact that subsoil facilities are not only the permanent structures meant for mineral mining and haulage but also the city and industry infrastructure, transportation lines, power generation and water bodies, high-rise structures, etc. for which underground rock mass and ground surface are the integral geotechnical component. All these subsoil use facilities are subject to risk of instability in case of natural and man-made disasters caused by deformation processes in rock masse and on ground surface. The current advances of geomechanics in the stress–strain analysis of rock mass, revealing its discreteness, mosaic structure and variability of stress and strain patterns in time, have offered a new insight into the sources and causes of natural and man-made catastrophes at the subsoil use objects and make it possible to push the limits of modern problems and objectives of geomechanics.

Keywords: geomechanics, safety, efficiency, subsoil use, deposit, mineral, rock mass, hierarchical block structure, geodynamics.
