Abstract:
Exploration, resource definition, and active mining operations can be located in terrains that contain geohazards such as rockfalls or landslides from natural slopes. To mitigate risks associated with working within these environments, controls such as hazard rating sheets have been developed for use by field personnel that enable escalation of assessment and implementation of mitigation measures as may be required to manage the risk. Where these risks are present in active mining operations, assessment of the natural geohazards must be integrated with ground control management tools such as ground awareness training, trigger action response plans, and geotechnical hazard plans. This paper provides an example of a site-specific framework for natural slope hazard management in the Pilbara and how GIS-based susceptibility mapping and rockfall hazard rating field assessment sheets are integrated into the operations ground control management system.

Keywords: natural slopes, landslides, rockfall hazard rating system, risk management
