ORE2 tailings tactical and strategic

As stated earlier ORE2_Tailings™ allows to define in a clear, transparent, and reproducible way which risks are tolerable or intolerable. Among the intolerable risks ORE2_Tailings™ allows to define which risks are tactical and which ones are strategic. We discussed tactical and strategic planning for dam portfolio using ORE2_Tailings™  in https://www.riskope.com/2021/06/30/tactical-and-strategic-planning-for-dam-portfolio-using-ore2_tailings/.  In our reports we show that risks of the considered portfolio belong to a three families as follows: tolerable, meaning they are below the risk tolerance of the client. These…

ORE2 tailings RIDM

We split this Chapter in two sections: section 10.1 discusses what actions one can take to enhance the knowledge base. These are obvious “simple” procedural mitigations. Thye lead to better understanding of the risks and/or to mitigate them. Section 10.2 shows how one can deploy ORE2_Tailings™ during the mitigation design process. That is in order to support decision-making. The goal is to define rational and sustainable risk mitigation programs. This process has to occur in parallel with the design by…

first steps ORE2 tailings workflow

First steps ORE2 tailings workflow: 2 – ARCHIVAL DOCUMENT SEARCH METHODOLOGY The archival documents delivered by the client to Riskope should cover the TSFs and their dams including: geotechnical studies; geological studies; design reports; geotechnical analyses reports; inspections; correspondence; incidents descriptions; dam break analyses; FIA and GISTM consequences evaluations; emergency plans; and finally monitoring (equipment and measurements as applicable). During the deployment we deliver an analysis of the archival gaps, i.e. a list of documents that are apparently missing or…

Sustainability, ethics and risks

Sustainability, ethics and risks results from a discussion we read on LinkedIN. The discussion arose after our friend Giuseppe di Capua cited SUSTAINABLE MINING – WHAT EXACTLY DOES IT MEAN? . The author of that paper is David Ovadia, for the @IAPG blog (https://www.geoethics.org/ ). The core of the discussion These days,  mining projects oftentimes tout their ‘sustainability’. The term reverberates from sources like the UN’s sustainable development goals. David Ovadia wonders if the term sustainable  can be used in mining.…

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…

Tactical and strategic planning for dam portfolio using ORE2_Tailings

Tactical and strategic planning for dam portfolio using ORE2_Tailings is the third of a series of blogposts explaining how to use ORE2_Tailings™ results. Indeed it follows: Dam portfolio ORE2_Tailings support for decision makers and ORE2_Tailings supports ICMM global industry standard on tailings management conformance. We use the same figures we have developed in those prior discussions. Summary of the portfolio ORE2_Tailings™ results With respect to probability of failure The portfolio of ten dams is made of two “bad apple” dams…

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.…
