7. Summary - Management of Potential Risks
Subsidence:
60m crown pillar as minimum
Geotechnical studies and monitoring
Mining sequence
Conservative stope design
Immediate back-filling after extraction
Ground control design
Vibration:
Drill and blast designs to meet criteria
Ongoing blasting assessment to conditions and potential receivers
Survey control to ensure separation distances are maintained with Perilya
Vibration monitoring
Scheduled blasting times and signage
Trigger action response plan indicates effects at surface
Infrastructure:
Civil engineer indicates no damage to roads, power lines or underground pipework
Noise:
All activities to occur underground, fans at 100m+ below ground
Study found no measurable difference
Air Quality:
Intake air Shaft 5, Exhaust air Shaft 6 located middle of CML7
Study found no measureable difference
