                      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.
