Abstract (in english)
   All significant events registered by continuous seismic monitoring system at the Jelšava magnesite mine during the period from July 17, 1993 to August 1, 1995 are described in the paper. The anomalous seismic development preceding significant geomechanical events on the background of normal seismic activity was discovered on the basis of seismic data acquisition. Criteria for prediction parameters of the slope of Benioff's sum graph and criteria for numebr of seismic events at the time window were found on the same seismic data. Necessary conditions for successful monitoring and prediction of these abnormal geocmechanical events were discussed. Sufficient density and sensitivity of the base of sensor, homogenous massif and on-line data processing in real time were determined as necessary conditions for successful prediction
