Application of FEM/DEM-DFN Modelling in Rock Engineering
Применение метода конечно-граничных элементов для решения геомеханических задач
rock mass fracturing due to stress redistribution; block caving - cave initiation, cave propagation mechanism, crown pillar collapse surface subsidence development; block cave - open pit interaction, rock bridge failure, slope stability
1. BLOCK CAVING
1.1. Influence of Geological Structure on Cave Propagation
contours illustrate vertical displacements 10cm(red)/1m(blue).
Note the role of joint orientation in initial cave propagation and the governing role of a fault in subsidence development.
1.2. Cave Development Mechanism in a Homogeneous Rockmass
1.3. Simulation of Block Caving and Surface Subsidence Development
1.4. Simulation of Block Caving and Surface Subsidence Development, Stalled Cave, Crown Pillar Failure
2. LARGE OPEN PIT - BLOCK CAVE INTERACTION
Illustration of block caving induced open pit slope instability: failure in rock bridges of non-coplanar step path joints dipping into the cave. more info
3. SLOPE FAILURE
Illustration of a joint controlled slope failure: rock fracturing initiation, failure surface formation, collapse and debris run-off.
