Rössing Uranium Mine is situated in the Namib desert approximately 65km from Swakopmund near the town of Arandis. This is one of the largest and longest-running open pit uranium mines in the world. The Mine was discovered in 1928 and was fully operational in 1976. The first phase of deep level vibrating wire piezometer was installed in 1988-89 with depths exceeding 450m.

Second Phase was installed in 1999 and a third phase during 2012 - 2013.

Rössing Uranium Mine Instrumentation consists of the following:

• Vibrating Wire Piezometers at pre-determent areas around the open pit, measuring pore pressure.

Instruments installed in and around the Mine are intended to monitor:

• Pore pressure build-up in and around the pit.
