The false promise of deep-sea mining. [PDF]

NPJ Ocean Sustain
Deep-sea mining of the international seabed could begin soon, despite concerns about its ecological consequences. We join others calling for a ban on international seabed mining, but for a different reason: it is a multi-billion-dollar solution to problems that do not exist.

Measurement and modelling of deep sea sediment plumes and implications for deep sea mining. [PDF]

Sci Rep, 2020
Abstract Deep sea mining concerns the extraction of poly-metallic nodules, cobalt-rich crusts and sulphide deposits from the ocean floor. The exploitation of these resources will result in adverse ecological effects arising from the direct removal of the substrate and, potentially, from the formation of sediment ...

Deep-Sea Mining With No Net Loss of Biodiversity—An Impossible Aim

Frontiers in Marine Science, 2018
Deep-sea mining is likely to result in biodiversity loss, and the significance of this to ecosystem function is not known. “Out of kind” biodiversity offsets substituting one ecosystem type (e.g., coral reefs) for another (e.g., abyssal nodule fields ...

Research and application of time-varying law of anchoring force of split-set bolt based on field measurement

Frontiers in Environmental Science, 2023
Split-set bolt is widely used in supporting stope and roadway surrounding rock in metal mines. The maximum pull-out force generated by the relative slippage between the anchor bolt and the drill hole can serve as an indicator for assessing its anchoring ...
