In this report the seismicity at three different sites was investigated during mining with backfilled and mining without backfill. In order to evaluate the effectiveness of backfill as regional support in reducing seismicity. The seismic parameters evaluated are total the number of seismic events and the total energy released, the number of events and energy released normalise to area mined MINSIM-D derived ERR values, b values and Y values. The results indicate, although not conclusively, that the seismicity has been reduced in areas where backfill had been placed. A factor complicating the evaluation of backfill on seismicity is the effect of geological structures on seismicity.
