... Abstract The Telfer underground sub-level cave (SLC) operations are located approximately 600 to 1000 m below the west wall of Main Dome open pit at the Telfer Gold Mine, Australia. The Telfer SLC commenced caving in 2006 and broke through to the surface in 2009 forming a large subsidence zone...

... ABSTRACT: Since several years, the demand for the storage of gas in rock salt caverns has changed from seasonal to high cycling operation. The new operation mode requires relatively fast pressure change rates in the cavern which in turn leads to temperature changes in the gas. The consequences...

As stabilization of the slope was not an option for several reasons, it was decided to replace the gallery by a new one deeper inside the slope, which will be ready for operation in 2017. Thus the old gallery has to be kept in operation...
