Acid mine drainage from mine wastes has caused detrimental environmental impacts in Australia and is recognised as one of the largest environmental liabilities facing the mining industry. Mining companies have to lodge hundreds of million dollars in bonds for perpetual treatment of potential environmental impacts. Federal and state regulations require mine wastes being managed in accordance with the 'current best practicable technology', which generally requires the placement of a soil cover over a waste deposit. The outcome of this project can assist the design of cost-effective site rehabilitation plans, which are crucial for sustainable development of the Australian mining industry.

矿山废弃物产生的酸性矿山废水对澳大利亚的环境造成了不利影响，并被认为是采矿业面临的最大环境责任之一。矿业公司必须提供数亿美元的债券，用于永久处理潜在的环境影响。联邦和州法规要求按照“当前最佳可行技术”管理矿山废物，这通常要求在废物存款上放置土壤覆盖物。该项目的成果可以帮助设计具有成本效益的场地恢复计划，这对澳大利亚采矿业的可持续发展至关重要。
