This is driven by a mechanical stress-deformation process that is initiated when the roof collapses in the mined-out area. Since entire coal basins recently have been closed in Europe, the focus has moved more to the long-term impact of mining. In various European coal basins, it has been observed that, after the mines were closed, there was a period of further residual subsidence, followed by upwards movement or uplift, which is linked to the flooding of the underground work areas.

Issues of sustainability will be given greater priority than in the first raw materials strategy from 2010, and for the first time aspects relating to post-mining will also be addressed. However, post-mining needs to be given much greater weight if the requirement for sustainability in the raw materials strategy is to be satisfied. Thus, Germany can set an example internationally and offer perspectives by referring to national practices and projects for a sustainable management of post-mining effects and in particular the consequences from phasing-out coal mining. It can also contribute to improving acceptance of the raw materials policy on a national level.<\/p>\n<p><strong>Author: <\/strong>Dr. Kai van de Loo, Gesamtverband Steinkohle e. V.

Electric power generation using hard coal was down by 31\u2009% in 2019. Over the three years 2017, 2018 and 2019, cumulative power generation from hard coal fell by 49\u2009% in comparison with 2016, i.\u2009e. by half. So the de facto exit from coal has been going on for a long time. If it were only a matter of reducing CO<sub>2<\/sub>, there would have been no need to make any decisions to phase out the generation of electricity from hard coal.<\/p>\n<p>Nevertheless, hard coal-fired power plants make an important contribution to supporting the expansion of renewable energy sources and to stabilising the electricity system. To prove this scientifically, the Verein der Kohlenimporteure e. V.
