Surface movement above an underground coal longwall mine after closure

Underground coal mining induces surface movement with damage to infrastructure. The best known phenomenon is the downward movement or subsidence during the life of the mine. However, it has been observed that after the closure of the mine there is first a period of still residual subsidence, followed by an upwards movement or uplift. This uplift is the direct result of the flooding of the underground workings. By conducting this research the long term impact of mining is better quantified.
