BLOCK CAVE MINING  (video)

 
Influence of geological structures on the development of surface subsidence, contours illustrate vertical displacements 10cm(red)/1m(blue). 

Note role of joint orientation in initial cave propagation and the governing role of a fault in subsidence development. 

 




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
