Abstract:
PT Freeport Indonesia’s (PTFI) Grasberg mining complex consists of some of the largest and deepest mines in the world, set within a complex geological, hydrogeological, and geotechnical setting. A risk-based approach to scope definition is implemented practically to manage hazards at underground operations. The approach focuses on identifying hazards, managing those hazards, and communicating risk from planning through operational stages. Risk management is centred around an online platform that enables users to reference hazards and determine initial, current, and residual risk ratings. PTFI’s approach to risk assessment enables management to understand the divisional risk across multiple technical disciplines and focus their efforts on scope definition, manpower and budget allocation to promote safety and achieve stated production targets. This paper provides details of PTFI’s approach to risk management, highlights challenges and realised benefits, and outlines the path forward for continued risk-based scope definition and hazard management.

Keywords: geoengineering, risk management, planning, scope definition
