Popis:	There are few effective remedial strategies capable of reducing or preventing pollutant loads from underground mines. The Gas Redox and Displacement System (GaRDS) is a new approach devised for stabilising sulphide minerals by manipulating the atmosphere in mining voids. This prevention technique offers the potential for passive, low cost, and effective control of acid drainage from underground mines at sites where flooding is not feasible. GaRDS utilises reducing gas mixtures generated by anaerobic bacterial activity to displace oxygen without impeding drainage from the workings. These gas mixtures halt sulphide oxidation and acid generation, and can precipitate secondary sulphides from the accumulated drainage water.
