Moment tensors of mining tremors: detection tool of the mode of rock-mass fracturing
Original language description
Traditional view about seismic events as exclusively shear slip phenomena has changed during recent decades. Advanced instrumentation and monitoring provide data which indicate events not matched by a simple double couple (DC). While earthquakes, in particular the strong events, are commonly assumed as shear slips, in foci of mining tremors physically a more complex mechanism may be expected due to injuring the rock mass by mine cavities concentrating the ambient stress. The mechanism in the moment tensor (MT) representation is an important discrimination instrument. To develop it into a reliable tool it is however vital to assess properly errors in the MT retrieval, particularly in the non-DC component determination, which is vulnerable to deterioration of the quality of records, station distribution, event location and velocity modeling.
