In many mining-intensive areas around the world, knowledge-sharing among companies is critical to advance best-practices in mine rehabilitation and closure. The academic literature documents innovative, best-practices options, yet these are often not accessible to field practitioners. Published mine closure plans provide relevant examples of standards accepted by regulators, however, regulations vary with jurisdiction and can change over time, limiting the utility of these plans. There is, therefore, a need for greater transparency and accessibility of practical knowledge to inform the definition of achievable completion criteria. The purpose of this study is to provide an overview of best-practices for the purpose of defining mine completion criteria. The methods comprise: i) a qualitative meta-analysis of the global peer-reviewed literature; and ii) three in-depth case studies in Western Australia. The research identifies ten key best-practices that could be potentially applied by mining proponents to guide the definition of successful completion criteria. These include: multiple references, monitoring and corrective actions, science-informed completion criteria, holistic rehabilitation, dynamic targets, leading indicators, integration of rehabilitation with mine operations, innovation-guided completion criteria, specific objectives and indicators and risk-based completion criteria. These best-practices are further examined through recent mine rehabilitation and closure programs of mid-to-large mining operators in Western Australia. Our findings provide the first comprehensive review of best-practices towards the definition of mine completion criteria, which are relevant to industries requiring rehabilitation of disturbed lands across Australian and international jurisdictions.

在全球许多采矿密集区，公司之间的知识共享对于推进矿山修复和关闭的最佳实践至关重要。学术文献记录了创新的最佳实践选择，但实践者通常无法获得这些选择。已发布的矿山关闭计划提供了监管机构接受的标准的相关示例，但是，法规随司法管辖区的不同而变化，并且会随时间而变化，从而限制了这些计划的实用性。因此，需要提高实践知识的透明度和可及性，以告知可达到的完成标准的定义。这项研究的目的是概述最佳实践，以定义矿井完井标准。这些方法包括：i）对全球同行评审文献进行定性荟萃分析；ii）西澳大利亚州的三个深入案例研究。这项研究确定了十项关键的最佳实践，采矿支持者可能会运用这些最佳实践来指导成功完成标准的定义。这些包括：多种参考资料，监测和纠正措施，科学告知的完成标准，整体修复，动态目标，领先指标，修复与矿山运营的整合，创新指导的完成标准，特定目标和指标以及基于风险的完成标准。通过最近西澳大利亚州中大型采矿运营商的矿山修复和关闭计划，进一步研究了这些最佳实践。我们的研究结果首次全面概述了定义矿山完井标准的最佳做法，这些最佳做法与需要在澳大利亚和国际管辖区恢复受灾土地的行业有关。
