TMW2022 discussion and video presentation

TMW2022 discussion and video presentation covers some important points and coveys our gratitude to the friendly colleagues that helped us overcome a significant work overload. Indeed, for the first time since 2013, we could not make it to the conference to present in person the results of our R&D. We were particularly sorry for this, as the reviewer wrote: The authors present a discussion on how to optimize actions needed to address risk mitigation to ALARP for a large TSF…

Tailings risks correlations

Tailings risk correlations or lack thereof refers to a phenomenon we oftentimes encounter in ORE ERMs deployments in various industries. The risk bubble in the p-C graph The figure below shows a classic simplified result from a ERM. The quadrant is the probability (p), Consequence (C) quadrant with the addition of the risk tolerance band. The band has a width corresponding to the divergent opinion between optimistic and pessimistic key stakeholders on tolerance. A given hazard has uncertainties on both…

Hunger stones refresh our short memory

Hunger stones refresh our short memory, they are indeed messages straight from the past. Those who endured droughts and resulting famine left them for their successors. Indeed, the hunger stones tell stories of severe hardship due to droughts. Of course they become visible when it is too late, as they are normally lying below water level (Hungersteine in the Rhine – Memory of great need – Experience Worms (worms-erleben.de). Today we will discuss if these events actually constitute divergence from…

Worldwide tailings benchmarks ten years later

A colleague sent us a paper by Rana, Ghahramani, Evans, Small, Skermer, McDougall and Take.  We reference it herein as Rana’s 2022 paper. The title is “Global magnitude-frequency statistics of the failures and impacts of large water-retention dams and mine tailings impoundments”. It is available online since Aug. 3rd 2022 at Earth-Science Reviews (2022), . I must confess at first I was quite intimidated. Almost a decade earlier we had written Factual and Foreseeable Reliability of Tailings Dams and Nuclear…

Tailings dams risk mitigation through risk informed decision making

Tailings dams risk mitigation through risk informed decision making (Tailings Dam Risk Mitigation Through Risk Informed Decision Making,) is the title of our PLANNING FOR CLOSURE 2022 paper.   Risk Informed Decision Making (RIDM) supports rational and sensible risk mitigation This blogpost shows how Risk Informed Decision Making (RIDM) using ORE2_Tailings™ supports rational and sensible risk mitigation selection. This is a requirement of the Global Industry Standard on Tailings Management (GISTM). We use an anonymized case report to preserve confidentiality.…

Zero to 300 in thirty

Zero to 300 in thirty is not the performance of a new sensational sport car. And we are talking about thirty years, not seconds! Actually, zero to 300 in thirty years is the cumulative experience Riskope and its founders have dealing with tailings dams risk assessments all over the world.  You should not understand it as an “average” evaluation either, as the evolution has been trending towards exponential. Let’s discover together what we are talking about. Zero to 300 in…

Impact of climate change change projections on tailings dams survivability

Impact of climate change projections on tailings dams survivability is the paper we presented at #CIMBC22 Climate Change and Tailings Management. The authors are M. Gloor, G. Halter, of Correntics (Correntics – we make global supply chains future proof) and Cesar and Franco Oboni. Image by TheOtherKev from Pixabay The session was brilliantly chaired by George Hemingway of Stratalis Three papers on Climate Change and Tailings Management  Charles Dumaresq presented the protocols for climate change consideration in mining projects. The…

FUV vs RIDM friends or foes at CIMBC22

FUV vs RIDM friends or foes at CIMBC22 sounds like a riddle, right? But it is not! Please, note FUV was actually never written as an acronym. Actually FUV stands for firmitas, utilitas, et venustas in Latin language.  Today we freely translate the terms into English as reliability, serviceability and beauty, straying a tad away from the original meaning. However, Henry Wotton, a seventeenth century translator, coined “firmness, commodity, and delight” as essential components of all successful architectural design. Wotton remained faithful…
