Compared to existing schemes, the decomposition of moment tensorsfor mining-induced seismic events into closing-crack and double-couplecomponents has the advantage that each can be interpreted in terms of aphysical source process (excavation convergence and slip/shear, respectively).Obviously, not every moment tensor permits such a decomposition, and wetranslate existing bounds on those that do to the Hudson source-type plot. Formoment tensors falling within these bounds, it has previously been noted thatthere will be a infinite set of possible decompositions in general. We derivean implicit equation defining this set and suggest physically motivatedcriteria that can be used to select a single decomposition from it.Furthermore, for moment tensors falling outside the source-type bounds, wepresent a simple geometric scheme for determining the closest moment tensorwithin them (which can then be decomposed). To demonstrate the methodsdeveloped in this paper, we apply them to two catalogues of mining-inducedseismicity.
