Water infusion has been used to control dust in many coal minesin Europe, the U.S.A., and Australia. The effectiveness of waterinfusion at a specific site has been shown to be constrained bythe physical characteristics of the coal, the geologicalenvironment of the coal seam, the effects of methane gas and theaccessibility of the coal seam. Consequently equipment andprocedures for infusion have been designed to suit a wide varietyof coals, environments and operating circumstances. This reportdiscusses the possible application of water infusion to theSydney Coalfield, and describes 3 case studies from other miningareas.
