Mining and mining damage
The mines in Limburg have an impact on our soil and even cause damage to houses. The mines were sometimes hundreds of meters deep. Working at that depth was only possible if the water level was kept artificially low by means of pumps. When the mines were closed, these pumps were turned off. The water level is now rising to its former level. That process is still ongoing.
What happens when the water rises?
The rising water level causes:
- The soil is slowly pushed upward.
- In the future, mine water may rise to higher groundwater levels and affect the quality of deeper groundwater.
We are monitoring this closely using additional monitoring wells and measuring points. Research shows that it will take decades before the water level is completely back in balance. For more information about the research and measures, visit:
- the Province's website
- Parliamentary Monitor website .
Mining
The changes underground can also cause problems above ground, such as houses with mining damage. More information about this can be found at:
- the website of the State Supervision of Mines
- the website of the Technical Committee on Soil Movement
- the Province of Limburg website .
