A mine site in regional NSW, currently under care and maintenance, required a solution to cap an existing tailings storage facility (TSF) using fly ash.

Mixing and deposition techniques and breaching characteristics needed to be confirmed in order to effectively assess the characteristics of the fly ash. Verifying strength parameters also needed to be determined during laboratory testing.

The flowable nature of the fly ash prior to setting meant innovative techniques were required to channel the flows and limit the spread of the slurry over the top of the TSF.

Rapid and easily constructed bund walls were required as a result that would minimise manual labour over the TSF surface.
