Abstract One possibility to estimate and to interpret the source parameters of low-stress drop seismic events to use the barrier or the asperity model. These models serve as the description of seismic events in a in which a horizontal room and pillar mining method is used in great depth. An additional macroseismic parameter, the destroyed or damaged area in the mine, allows the estimation of the real static stress drop of mining-induced seismic events. This stress drop, derived from a simplified barrier-or asperity-model, appears to be a constant and a characteristic parameter for a given source region. On this base, a relation between the underground destruction or damages and the seismologically estimated parameters is derived and is used for the classification of the mining-induced seismic events.
