Rock mass geodynamics and mining-induced rockbursting at Nikolaev complex deposit

Critically Stressed Areas of Earth’s Crust as Medium for Man-caused Hazards

“…Evaluation of the stress condition of the massif is the key to understand the conditions for occurrence of geodynamic phenomena [1][2][3][4][5][6][7][8][19][20][21][22][23][24][25][26][27]. Tectonophysics methods here have an important advantage over instrumental methods because they give a possibility to investigate the stress condition of large volumes of rock massif based on analysis of rock slabs shifting along current faults [18,28].…”

“…Geodynamic safety issue remains to be high on the agenda in various mining areas of the world [1][2][3][4][5][6][7][8][9]. Significant success has been achieved in Russia in solving rock burst problem, methods of forecasting and prevention have been developed, geodynamic mechanisms have been learned.…”

Improving geodynamic monitoring practice in underground gas storage areas

“…The establishment of such a relationship is one of the most important results of geomechanical and geodynamic research in the past century [9]. Aggravation of induced seismicity, abnormal deformations of the earth's surface, integrated environmental effect of geodynamic processes [10][11][12][13][14][15][16][17][18][19] are observed in mining regions. Taking into account current understanding of the hierarchical-block structure of the rock [3,[20][21][22] ] the presence of regional and local tectonically stressed and unloaded zones therein, including zones of critical stress [23], achievement in field of monitoring [24][25][26][27] it can be assumed that the inclusion of engineering facilities such as UGSs into this natural system can also lead to their geodynamic interaction and mutual influence.…”

Evaluation of deformation characteristics of brittle rocks beyond the limit of strength in the mode of uniaxial servohydraulic loading

“…With an increase in the productivity of underground mining deposits development, in order to maintain the pace of production, it is necessary to open up new horizons, which are often deeper than existing ones. With an increase in the depth of development, the risks of complication of the geotechnical situation increase [1][2][3], which can manifest themselves in the form of increased rock pressure, including in a dynamic form [4][5][6]. For example, the depth of development of the Talnakh mines in some areas reaches more than 1000 m with a critical depth of rock-burst hazard of 700 m [7][8][9].…”
