Impact of the closure of a coal district on the environmental issue of long-term surface movements KU Leuven
Long-term impact of coal mining on surface movement: residual subsidence versus uplift KU Leuven
It is well known that longwall mining leads to a significant amount of surface subsidence. 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 ...
Upward surface movement above deep coal mines after closure and flooding of underground workings KU Leuven
© 2017 After the mass closures of entire coal mine districts in Europe at the end of the last century, a new phenomenon of surface movement was observed—an upward movement. Although most surface movement (i.e., subsidence) occurs in the months and years after mining by the longwall method, surface movement still occurs many decades after mining is terminated. After the closure and flooding of underground excavations and surrounding rock, this ...
