Design of roadway support in coal mines
Šňupárek, Richard
Design of roadway support in coal mines is mostly based on simple united methods for designating of support loading and for design of support constructions. These methods are based in majority of cases on practical engineering processes with using of empirical knowledge from the area of interest (mine, deposit, stratigrafic unit). In cases with similar conditions it is possible to compare the methods of roadway support design. The contribution deals with comparison of design methods used in Ostrava Karviná coal basin and Ruhr coal basin in Germany.

Monitoring network with telemetric data transfer realized in medieval Jeroným Mine
Kaláb, Zdeněk ; Knejzlík, Jaromír ; Lednická, Markéta
To have more detailed information about rock massif behaviour, distributed control and measurement network for evaluation of hydrologic, geomechanical and other parameters has been built up in the medieval Jeroným Mine from the first half of 2006. Instrumentation is generally based on commercial control kit and sensors. This network is integrated to the seismic recording apparatus equipped by data transmission via GSM network to registration centre in Ostrava. Completely monitoring system is performed as modular to have possibility to change configuration of this system.
