ABSTRACT
With the excavation of mine the former equilibrium
of the primary stress in the raw mountains is gener-
ally disrupted. In order to get sufficient stability a
new state of balance will be formed gradually and
the mountain deformation will be also induced by
stress redistribution, which depends on the mining
dimension, cavity geometry and the rock mechanical
behaviour. Because of the mining in the mountain, a
specified volume of convergence will be generated,
which can be seen as the direct relationship between
the underground deformation and the surface
movement.
