Abstract

The use of hydraulic devices plays an important role not only in the roof support but basically all coal extraction activities. Hydraulic devices has been essential for many years and during that time was significantly changed and improved. In this diploma thesis I will deal with new powered hydraulic devices used in OKD for roof support and other support means, which has been used in mines for many years. These technologies and means will then be compared depending on the assembly complexity, the requirements for worker qualification and ease of use in the actual mining. In the end I will summarize technologies and means most suitable for OKD.
