Monitoring of the operational and geomechanical mining conditions in a longwall face situated in a difficult rockburst prone area - a case study

The paper describes a case study, i.e. planning and winning a longwall face operated in the seam endangered into a great extent by rock bursts on a mine in the Ostrava-Karvina Coalfield, Czechoslovakia. The basic operational, geomechanical and geophysical monitoring systems incl. specification of them are described along with the basic information on the evaluation of the measured parameters and their use for the face works management. Some practical problems dealing with the monitoring results utilization and possible ways of the future monitoring application in hardcoal underground mines are also discussed.
