abstract: This paper aims to describe the changes in stress and rock mass conditions during 13 years of deep mining.
Stoping in originally high stress environment has led to detachment and subsidence of remaining oreblocks
along schistosity surfaces of the immediate wall rock, while high-stress related seismicity has moved further
from the actual mining area. Also presented is history of numerical stress modelling and its correspondence
to the observed rock mass behaviour. Finally, adjustments made to mine planning, production and ground
monitoring are described.
