Rock burst hazard assessment of apatite mines on Kola Peninsula by means of local acoustic emission method
Various acoustic emission (AE) parameters are used to characterize fracture process in rocks. The conventional statistical values are, for example, AE activity, b-factor, and distribution of energy. In order to map AE events the location analysis is used. There are also of interest in seismic analys...
