MAP 3D analysis of secondary stress field structure in face area of development headings in rockburst-hazardous seams

The article describes the research aimed to study and control the secondary stress field in face areas of development headings in rockburst-hazardous seams in the Internatsionalny Mine, as well as to model the stress–strain behavior and to obtain the qualitative estimate of rock mass condition. The authors present the resultant estimates of safety of the accepted drivage and roof support designs for development headings, excessive stresses and safety factor of rocks mass, as well as deformation of headings in beige rockburst-hazardous and grey dolomite rocks at different depths. The calculations were performed for six scenarios of intersection of beige rockburst-hazardous dolomite seams by a heading. The stress–strain behavior of surrounding rock mass around development headings in rockburst-hazardous seams was modeled in Map3D. The quantitative analysis results are currently used for the model calibration for the whole period of drivage and reinforcement of underground openings of spiral decline and motor transport ramp. Based on the modeling, the structure of secondary fields of stresses and strains during development heading in rockburst-hazardous rock mass has been determined.
