methodologies employed are <strong>of</strong> value to o<strong>the</strong>r underground environments excavating in disturbed<br />
ground, and may show more positive results in cases where faults are geologically weak.<br />
5.3 Recommendations for Future Work<br />
Based on <strong>the</strong> results <strong>of</strong> this study, <strong>the</strong> following recommendations are made:<br />
<br />
Continued monitoring <strong>of</strong> seismic event parameters should be carried out in order to identify<br />
signs <strong>of</strong> fur<strong>the</strong>r rock mass degradation. Extra caution should be given to <strong>the</strong> area identified as<br />
Cluster 1. This is identified as an area <strong>of</strong> increased hazard and continues to be a source <strong>of</strong><br />
energetic events. Fur<strong>the</strong>r studies <strong>of</strong> events in this area may help characterize and understand<br />
anomalous activity in this area.<br />
<br />
Additional triaxial sensors are recommended to improve location accuracy and to facilitate<br />
fur<strong>the</strong>r seismic studies in <strong>the</strong> Creighton Deep. Denser spacing in key areas <strong>of</strong> interest may<br />
also facilitate studies.<br />
A comparison <strong>of</strong> fault plane solutions for microseismic events with joint fabric on <strong>the</strong> 7400<br />
Level is suggested as future work. A correlation with joint planes may explain <strong>the</strong> deviation<br />
<strong>of</strong> estimated fault plane orientations from mapped fault orientations.<br />
<br />
Moment tensor inversion for microseismic events is recommended to study <strong>the</strong> damage<br />
process and characterize seismicity. Mechanisms such as crack dilation and closure could be<br />
identified using this method. Moment tensor inversion may also be a suitable method for<br />
studying events in Cluster 1.<br />
<br />
Fur<strong>the</strong>r analysis <strong>of</strong> macroseismic events is recommended once <strong>the</strong> triaxial strong ground<br />
motion system is calibrated. Waveforms recorded by <strong>the</strong> calibrated triaxial system will allow<br />
