Research into deformation processes in the rock mass surrounding the stoping face when mining sloping ore deposits)

Purpose. Determining the patterns for geomechanical state changes in rock mass, depending on stoping face technological parameters sloping ore deposits. Methods. The state-of-the-art CAE Fidesys strength analysis system has been adopted to conduct research processes around face, which is effective a flat formulation. used provides complete engineering process cycle from preparation of calculation model visualization results. real physical-mechanical properties ores and host rocks Zhezkazgan field (Kazakhstan) are initial data. Findings. As result, change stress-strain have obtained, namely, maximum tensile compressive deformations room fenders parting, its thickness (from 0 10 m). Based data it revealed that studied mining-geological conditions, elastic predominate face. Originality. result conducted numerical experimental studies, new solution proposed an important scientific problem related predicting natural technogenic mass. Practical implications. results obtained make possible develop technical solutions modernization room-and-pillar (panel-and-pillar) mining under conditions fall bodies field.
