ORE2-Tailings dam analysis

Welcome to ORE2-Tailings dam analysis ORE2-Tailings dam analysis delivers value to the mining industry. In addition it supports communication between owners, regulators and the public. That is quickly and at affordable costs ORE2-Tailings dam analysis is beneficial for those who: design, permit, construct, operate, insure and finally, perhaps close,tailings/waste storage facilities in the mining and oil & gas extraction industry.

Opportunity, experience, learning from mistakes and regrets

Opportunity, experience, learning from mistakes and regrets come up in many conversations. Examples generally start with a IF: I had known what I know now. It would be possible to start over again. A second chance would be possible. It seems like we really firmly believe we can learn from prior mistakes. We can absorb lesson learned and profit from them. However, there is abundant evidence that is not the case. We tend to repeat patterns, even if we know they…

UNEP Tailings Dams report and residual risk assessment

UNEP Tailings Dams report and residual risk assessment discusses the joint UNEP-GRID Arendal assessment entitled “Mine Tailings Storage: Safety Is No Accident” from a risk assessment point of view. The United Nations Environment Programme (UNEP) released the report in October 2017 in Geneva. The report urges States and the industry to “end deadly and damaging mining waste spills by enforcing a zero-failure objective”. We believe that this objective requires some additional definitions and details. That is to make it truly…

Sendai Framework for Disaster Risk Reduction and the mining industry

This “Sendai Framework for Disaster Risk Reduction and the mining industry” blogpost looks at what constitutes a minimal requirement for a Risk Assessment applied to a mining orphan site in 2013. That occurred as a result of Public Hearings in the NWT. It then examines recent development in the field, welcoming the apparently general request for multidimensional consequence analyses. A bit of reminiscing For the reclamation of Giant Mine the MVREIB, an Environmental Review Board in Arctic Canada quoted the…

Technical session towards improving environmental social disclosure NI43-101

Below are my views of the various presentations heard at CIM2017 in Montreal, during the Technical session towards improving environmental social disclosure NI43-101. Various talks, from various speakers, who shed some light on this multi-faceted theme were the trigger to this blogpost. Each one came from his or her own line of business and interest, including myself. Technical session towards improving environmental social disclosure NI43-101 There was a broad consensus that risks are not only “technical” matters any more. The…

Oroville Dam risks became unmanageable?

In the case of Oroville dam, the population exposed to the potential dam failure has increased significantly. Normalization of deviance increased the probability of failure. So is it possible that Oroville Dam risks became unmanageable because of that? Oroville Dam risks became unmanageable? When looking at risk mitigation the old saying is that you can either lower the probability or lower the consequences. That statement requires some explanation. Indeed what mitigation alone can do is exclusively to reduce the probability of…

Negligence by the state contributed to the triple Fukushima 2011 meltdown

A Japanese court has ruled that Negligence by the state contributed to the triple Fukushima 2011 meltdown. So, this time it is not a negligence related to a landslide, a dam breach or a flood. It is negligence related to a major nuclear accident (Factual and Foreseeable Reliability of Tailings Dams and Nuclear Reactors -a Societal Acceptability Perspective) to be in the center of a lawsuit. As far as we know it is a first in the world. Negligence by…
