Subject aims expressed by acquired skills and competences

Students should be able to work independently in the field influence by undermining, especially in solving problems related with the determination of subsidence trough parameters and the theoretical calculation of surface movement.

Summary

The task of the influence by undermining is to clarify mechanism of overlying rock due to underground mining and mining results on the landscape. One of the main tasks of the influence by undermining is a theoretical calculation of the movements and deformations, depending on the extent of planned mining.
