The focus is on how different risk analysis tools and procedures can be used effectively, while also highlighting limitations of some of the most popular tools. A strong case is made for a critical assessment of the effectiveness of risk-management tools. Finally, the paper discusses the challenges of understanding and communicating geomechanical mining risk, given the asymmetry of knowledge and information by decision-makers in mining companies. Keywords: geomechanical mining risk, underground and surface mining, risk tools, asymmetry of knowledge
