Underground mine stability becomes one of the problems which is need to be considered when open an underground mine. The high stress around the openings increase along with the increasing depth, it can trigger seismic activity which is cause seismic hazards. Rock mass around the opening that exposed to seismic event could experiencing rockburst that can lead damage potential to underground mine opening, workers, and the support system. Therefore, a microseismic monitoring system is required in order to understand the rock mass response in mine area and to reduce the possibility of seismic risk. XYZ underground mine at PT ABC uses block caving as the mining system. The location of observations in this study is only at Panel 10 until Panel 20 at the production level. By using microseismic data that provide changes of local geology and stress condition, the objective of this study is to determine the rockburst damage potential because of seismic events from April 2016 to March 2018. After data processing is done, it is found that panel damage at production level is on the scale of R1 to R5, with average damage on R2 scale. The worst damage was experienced by Panel 13 in October 2017 and January 2018 with the damage scale reaching R5 at the junction area.
