Case story

Cleanout of Coal Mine Settling Ponds

Indonesia, South Kalimantan

A large Indonesian mining corporation operating an-open-pit coal mine in a remote part of South Kalimantan,  faced a problem on how to dewater silt sediments from settling ponds that had reached their capacity.

A TenCate Geotube® dewatering facility was constructed to contain and dewater slurry extracted from the ponds. More than 300 Geotube® units have been used to dewater more than 1,000,000 m³ of sediments containing 170,000 m³ of dry solids annually. To optimize land space, the Geotube® dewatering tubes are stacked up to seven layers high.

This project has the distinction of being one of the biggest Geotube® dewatering projects ever undertaken in the world providing a wealth of knowledge on the economics of extreme large scale Geotube® dewatering.
