Sensitivity analysis of factors influencing flooding
How is the rise in mine water influenced by various parameters?
When an underground mine is closed down, there is no longer any need to pump out mine water in order to ensure underground mining operations. As a result, the mine water level rises. This happens gradually via natural inflows such as groundwater or seepage water. The rate at which the mine water rises depends heavily on the hydrogeological and mining characteristics of the respective site.
In the project, the researchers at the Research Center of Post-Mining (FZN) examine these different characteristics in detail. To this end, in a preceding project they developed a corresponding analytical model, which they have already successfully applied to simulate mine water rebound in three selected mines. The analytical model is characterized by the fact that mine water rebound can be simulated in a comparatively simple and fast manner and with sufficient accuracy. The model’s analytical approach makes it possible to vary site parameters in a targeted way in order to draw conclusions about their influence.
The project is funded by the RAG-Stiftung over a period of three years.
Project objectives
- Verification of the analytical approach through application to further mine water rises in disused mines
- Extension of the analytical approach to a more complex deposit structure
- Testing the sensitivity of parameters to the rise in mine water levels and the development of the inflow rate
- Development and expansion of the analytical approach as a forecasting tool for future mine water rises
