"Traditional assumption about a seismic source as a double couple (DC) can represent a serious limitation for describing mechanisms of mining induced seismic events. In mining conditions more general process than a shear slip can occur due to stress concentration on mined-out areas. We assume both non-DC components within the dipole description of the source \u2013 the moment tensor, and a single force. We processed five seismic events recorded at Driefontein gold mine in South Africa to demonstrate that waveform modeling is not successful enough due to poor information about the medium. Inversion of amplitudes of direct P- and S- waves is more prospective due to their smaller sensitivity to detail of the medium. All five events processed display non-DC mechanisms which are significant at 95% considering the mismodelling of the rock mass by a homogeneous isotropic medium. The source mechanisms are in agreement with the underground mining and geological structures."@en . . "396198" . "000258433000002" . . "Milev, A." . . . . .
