Determination of the stress-strain state of rock mass and zone of inelastic deformation around underground mine excavation using modern methods of numerical modelling
نویسندگان
چکیده
The paper reviews methods and trends of numerical modelling geomechanical processes around underground mine excavations. most rational method determining the additional stresses caused by excavations is chosen. Mathematical was performed for various cross sections different strength rocks. dimensions inelastic deformation zone have been identified. area total fracture excavation, as well roof are calculated. results presented both coordinates in a graphical form. To simplify application results, dependency plots obtained parameters were created analytical dependencies SURFER KOMPAS software packages used graphic tools to visualize
