description: 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.
