Subject aims expressed by acquired skills and competences
The course aims to acquaint students with the characteristics of the original
přetvárného state of stress and rock mass and its changes during the excavation
mine and subsequent conquest. Students should use the knowledge of the subject of rock and soil mechanics to practical calculations with regard to the design of reinforcement, and forecasts of anomalous phenomena.

Summary
This subject deals at the first with stress and deformation state of rock mass
before mining activities. Than follow on changes in the rock mass during
mining activities. Separately it is explained for linear mine workings and for
large mining workings. For mining methods with pillar leaving, dimensioning of
that pillar is important. At mining methods like long walking stress-
deformation state of rock mass is important for right choose of technological
arrangements. The attention to the anomalous rock mass behaviour is paid.
