Evaluation Of Measurement System For Monitoring The Stability Of Roof Bolted Roadways With Rectangular Cross Section By Selected Examples

To detect improper deformations of a roof bolted roadway in order to reduce inner mine damages in the most early stage and to initiate suitable countermeasures if necessary, several different measurement systems were used for monitoring a roadway's stability on the hardcoal mine "Auguste Victoria" (DSK AG). In this paper the different convergence measurement procedures are described and their respective results are introduced. Subsequently the results of the single measurement methods and procedures are correlated with each other.
