Dewatering wells in open cast mining

Level measurement in groundwater control in dewatering wells

Level measurement in groundwater control in dewatering wells

Process data

Measuring task:
Level measurement
Measuring point:
Deep well
Measuring range up to:
750 m
Process temperature:
+4 … +10 °C
Process pressure:
0 … +10 bar
Special challenges:
Heavy deposits and buildup due to clay content in the water


In open cast mining, the groundwater levels must be continuously reduced to protect the mining area from flooding and the excavation walls from instability due to water pressure. A large number of dewatering wells with submersible pumps are kept in operation for this purpose. A continuous water flow prevents the pump shaft from blocking due to the effects of hardening clay/iron oxide deposits. To regulate the pump output, precise level measurement is required in each of the up to 750 m deep wells.
