Tailings dam mitigation risk informed decision making

Tailings dam mitigation risk informed decision making closes the discussion we presented in prior blogposts. We now focus on one dam and show how ORE2_Tailings™ supports rational and sensible risk mitigation decision-making as requested by GISTM. The dam case The dam we selected for this example is inactive and is parallel to a valley bottom. An unprotected creek runs at its toe and the bed is considered to be sufficient for the 1/500 return. Beyond that flood, there will be…

Dam portfolio ORE2_Tailings support for decision makers

Dam portfolio ORE2_Tailings support for decision makers follows-up on a prior example. We will show how to interpret the graph we present in that prior post. Dams probabilities of failure and ORE2_Tailings benchmarking at portfolio level. The portfolio of ten dams is displayed on the annualized probability of failure graph, together with the world-wide benchmarks. This graph shows dams: AA1 entirely under the benchmark range, AA3 straddling the benchmark range (uncertainty on the worse case pf estimate slightly above benchmark),…

Dam portfolio ORE2_Tailings support for ICMM standard on tailings management.

Dam portfolio ORE2_Tailings support for ICMM standard on tailings management (GISTM) is multifaceted. ORE2_Tailings™ is a risk assessment platform specifically Riskope designed specifically for tailings systems. When we deploy it to a portfolio of dams, possibly over multiple properties, it allows for tactical and strategic planning. We have already discussed the single dam case in relation to ICMM • Global Industry Standard on Tailings Management (2020)  and the conformance protocols. Today we present an example of deployment at portfolio level.…

ORE2_Tailings supports ICMM global industry standard on tailings management conformance

ORE2_Tailings supports ICMM global industry standard on tailings management conformance (GISTM). ORE2_Tailings™ is a risk assessment platform specifically designed for tailings systems created by Riskope.   We recently published the notes we took while reading ICMM guidance and conformance protocols. In that text we stated that ORE2_Tailings™ anticipated the requirements of ICMM GISTM. Indeed, the threads of our publications, which culminated with Tailings Dam Management for the Twenty-First Century shows that evolution. Today we bring to your attention an example…

Reading the ICMM Guidance and Conformance protocols

We started reading the ICMM Guidance and Conformance protocols with great interest and were pleased with a number of specifications we saw. Of course, an endeavor of this magnitude and scope will stir a lot of interest in the mining world. From our end, given our long experience in tailings system risks, we could not resist to compare the protocols to our day-to-day practice. We noted areas where more detailed explanations would likely benefit the mining industry and the public.…

The impact of standard of care on dams survivability

Using ORE2_Tailings we can quantify the impact of standard of care on dams survivability. In this blogpost we take three dams, namely Dam x, Dam y and Dam z. Their design was identical with initial factor of safety of 1.3. In addition, they had similar QA/QC, construction method, same systemic approach, efforts and uncertainties consideration. Various small mishaps hit the dams along their history. Some repairs occurred, under different contracts, different quality control and finally, at different times. It turns…

Tailings dams failures insurance perspective

It is interesting to read about Tailings dams failures insurance perspective. Riskope helped solving miners’ insurance denial issues for the last 15 years. Riskope also recognizes the issue is becoming much wider than mining due, for example to climate change impacting residential and private parties. Tailings dams Recent papers from Willis Towers Watson  quote tailings dams failures frequency at two failure per year. In a 2013 paper (Oboni, C., Oboni F., Factual and Foreseeable Reliability of Tailings Dams and Nuclear Reactors -a…

Quantitative Convergent ERM to Solve Real Life Problem

Riskope presented at Infonex (https://infonex.com/ ) Quantitative Convergent ERM to Solve Real Life Problem. The conference was carried out on Zoom and the talks were, of course recorded. What is ERM?  Enterprise risk management (ERM) is a plan-based decision-making support. It allows its users to enhance their tactical and strategic planning and therefore to increase competitiveness. Indeed, it aims to identify, assess, and prepare a project, corporation to cope with threats and hazards. Threats and hazards can occur with different…
