Changes in strain and slope geostructural block in the preparation and realization of technogenic eathquake

Article preview

The results are presented of deformation and rock mass block inclination in the underground mine field for the long period of time including different stages of preparation and realization of the earthquake. The stable mid-term and short-term earthquakes precursors are identified. The result analysis has been made within the hierarchy-block geological model of environment.

Experience in expert systems application for estimation of stress- strain state of rock mass for selection of safe methods of ore deposits mining

Article preview

The method of successive geomechanical estimation of stress-strain state of rock mass at different scale levels was developed. This method allows to carry out the regional and local prediction of formation of stress concentrated zones, and also to develop and adopt technology, which provides the decrease of dynamic rock pressure manifestations and rock burst prevention at mineral deposits.

Safety problems of mining operations in high-stress hard rock massif

Article preview

Intensive development of large-scale deposits in high-stressed rock masses results in sharp activation of mining-induced processes in the earth depths and the surface thus initiates increasing of seismic activity in the mining area and hazard of rockbursts and mining-induced earthquakes. As reliable spatial-temporal prediction of dynamic events in the mines is problematic in the current state of methodology and geomechanical experiment technique, therefore, it is required to assess risks of  these events which scale determines corresponding preventive measures.

Numerical assessment of stress-strain field in vicinity of large open pit mine taking into account geomechanical, geological and mining factors

Article preview

The results of modeling of rock mass stress state in the vicinity of large open pit mine using finite-elements method are represented. The model allows to take into account the influence of large-scale fractures. The initiation of boundary conditions is based on the results of determination of stress parameters in situ. The locations of risk areas near the slope are defined.
