Analysis of rock burst realization conditions in the Rasvumchorrskiy mine of "Apatit" JSC in 14.02.2012
The results of numerical research of stress-strain state with the actual mining state during rock burst in the Rasvumchorrskiy mine of “Apatit” JSC in 14.02.2012 are presented. The stress redistribution in the contour rock mass after relief boreholes drilling was analyzed. The optimum angle for repeated drilling of relief boreholes row is proposed.
