  Prediction of mining-induced surface subsidence and ground movements …

  2017121 · Introduction Subsidence is the downward settlement of the ground surface. Mining-induced surface subsidence is a phenomenon that occurs due to the underground extraction of an orebody. Open pit and underground mining operations cause stress redistribution; consequently, this causes some induced displacements on the ground …

  Evidence of the impacts of metal mining and the effectiveness of mining ...

  2019221 · Mining can yield a range of benefits to societies, but it may also cause conflict, not least in relation to above-ground and sub-surface land use. Similarly, mining can alter environments, but remediation and mitigation can restore systems. Boreal and Arctic regions are sensitive to impacts from development, both on social and environmental ...

  Prediction of sub-surface subsidence movements due to underground …

  The theoretical model of the relationship between sub-surface and surface subsidence movements proposed earlier by the authors of this paper is briefly described and further tested against another case history example. Using this model, the magnitudes of the maximum subsidence, tilt and horizontal strain at sub-surface horizons between the …
