Methods and techniques for control of rockburst-hazard in underground mining at ore mines of the Far-East district

An assessment is given to the present-day state of control of dynamic rock pressure manifestations in the rockburst-hazardous ore mines of the Far-East district. Consideration is given to the used methods and facilities for control of rock pressure and the ways for their improvement . Basic foundations of methodical approaches to the assessment of geomechanical state of rock mass by data of geoacoustic control are considered.

Influence of blocky-hierarchy structure of geological medium on the forming of natural and technogenic geodynamic fields in the North-West part of the Amur geoblock

On the example of the South-Argun uranium ore district of Zabaikalie consideration is given to the interaction of regional and local fields of stresses. The district includes a number of deposits prone to rock bursts. The performed analysis contains data on recent geodynamics of the explored part of the Amur geoblock as well as on geomechanical and geologo-structural materials of Tulukuev caldera and of Antey deposit. It is shown that with the use of the M.A. Sadovsky relationship the indices of local structural forms of a row are subjected to unified laws of deformation and fracturing. Conclusion was made that at the beginning of deposit exploitation the direction of action of stress field within rock mass conformed to regional one, and then it considerably changed under influence of large-scale mining operations.

Control of dynamic rock pressure manifestations in mining the «Antey» deposit

The article considers the conditions and pattern of dynamic rock pressure manifestations in mining the «Antey» deposit of uranium ores. Data on geological, technological and geomechanical conditions of the deposit mining are given. The methods and means for rock pressure control are described as well as the results of their application at deep horizons of ore mine are given.

Modeling of geomechanical processes in mining the steeply pitching ore bodies of rockburst-hazardous deposits

The article contains the results of numerical modeling of stress-strain state in constructive elements of mining systems, applied at hazardous and prone to rook bursts deposits of the Far-East. Consideration is given to some stated regularities of forming of teсhnogenic stress field and geomechanical processes proceeding in rock mass of minable deposits which allow to substantiate a сomplex of measures for prevention of dynamic rock pressure manifestations.
