Challenges in German subsidence research – retrospectives and perspectives

Preusse A., Müller D., Beckers D.

T. 20, nr 1

Due to the fact of a multilateral underground use, mining subsidence relocates more and more from mining to other issues, like post-mining topics, storage or geothermal utilization. This and the infl uence of the energy policy is why the situation in Germany also describes a transition from active to abandoned mining. Many PhD-theses with different subjects were written within the last 20 years. Every single one with a different topic but all with the same issue: Mining subsidence and its effects and challenges. These challenges start with the research regarding geological and hydrogeological conditions, which is the basis for calculations like the angle of draw or predictions of subsidence due to water table drawdown. Furthermore, the research investigates issues like risk-management and fi nancial planning. One of these issues are post-mining calculations and another for example potential hazards of storage or the use of geothermal energy. This paper outlines an overview of German Mining and its consequences due to subsidence. It deals with an overview of the circumstances relating to hard coal mining, lignite mining the use of geothermal energy, gas and opportunities regarding underground storage. Basically it describes the essential steps of processing of mining subsidence, starting with monitoring to forecast and up to safety measures. With a glance back to the applied research of the prior two decades, we compare given forecasts with experiences already gained. Even though mining decreases, ground control does not.
