Mine areas left behind by companies that no longer exist are defined as derelict mines – those that were operated and closed at a time when most countries did not have adequate regulations requiring rehabilitation of the impacted mine areas. This book provides unique information on the extent and severity of derelict mines’ impact on environmental degradation and human and environmental health. It examines the nature of derelict mines, short-term and long-term risks to sensitive receptors, tools for monitoring and prioritizing risks, and technological advances for rehabilitation. This book considers a risk-based approach to managing derelict mines, which is reliable and cost-effective. FEATURES Provides fundamental information on derelict mines and their inventory in different countries Explains risk-based management of derelict mines and the importance of community perspectives as a reliable and cost-effective method Identifies ownership and liability issues through many case studies in Australia and other countries that must deal with the remediation of derelict mines Presents remediation, assessment, and predictive tools for managing pit lakes Helps readers set standards, regulatory measures, and policies related to mine closures This book is for engineers and professionals who work in mining, geology, chemistry, mineralogy, geotechnics, and hydrogeology and deal with industrial site management, waste management, mine closures, mine site reclamation, derelict mine remediation, and mine revegetation. It is also an insightful resource for graduate students, academics, and researchers focused on these courses.

When mining activities cease, its environmental impact continues as a consequence of which all the adjacent vegetation, soils, groundwater, etc. are exposed to a very high concentration of heavy metals. The toxic heavy metals present in the tailings or ‘spoils’ of abandoned mines migrate to the surroundings and cause severe and widespread contamination of farmland soils and water bodies leading to the onset of geo-environment disasters. One such example is a recent one in Brazil that released 60 million cubic meters of mine waste due to iron-ore dam burst according to The Guardian daily dated 28 November 2015.

This book provides the most comprehensive survey of mining activity and the principal challenges confronting the resources industry in the Asia-Pacific region today, and presents new theoretical and practical insights into the political and business risks faced by mining companies operating in the region from both academic and corporate perspectives. It focuses on the exploration, production and trade of the principal commodities coal, iron ore, uranium, oil and gas, and gold, as well as the emerging commodities unconventional gas and rare earth minerals, provides the reader with a valuable understanding of resource activity in the region. In addition, it also integrates and draws attention to eight key issue areas which have the potential to pose significant risks, challenges and opportunities for the industry going forward, which include sustainable development, resource governance and economic contributions, declining ore grades and territorial expansion, community aspects of mining, mining and indigenous peoples, climate change, and impact assessment. The contributors to this volume are experts in their respective fields, and the diversity of voices makes this book a must read for scholars, industry participants, investors and policy-makers with an interest in mining in the Asia-Pacific.​

Acid mine drainage (AMD) has generated an enormous amount of media interest and public concern in the Gauteng City-Region (GCR) over the last decade. However, it has been framed as a narrow technical concern, with government action being directed towards securing the necessary engineering and processing solutions as quickly as possible to prevent decant and treat acid mine water to industrial standards. This has arguably limited the scope for full discussion and debate on the impacts of AMD, particularly for the environment, and this bears implications for how AMD has been managed in the GCR. Government’s immediate, short and long term interventions to address AMD have been set out as a straight forward solution, but over time more complex environmental concerns have emerged. Becoming more evident over the last few years is that one of the main impacts of AMD will be its effect on the overall water security in the Vaal River System (VRS) on which the GCR relies for its supply of potable water. Limits on water abstraction from the VRS, together with the increasing need to maintain the overall water quality in the system through dilution and treatment activities, means that AMD is beginning to manifest as a binding constraint on economic development and a burden on society – in particular via escalating costs for water consumers. Fiscal constraints are likely to see GCR residents and businesses pick up more and more of the costs associated with the treatment of AMD, through the format of increased municipal tariffs. With final decisions on municipal tariffs now pending, the broader yet invisible impacts of AMD loom large. This means that the debate has moved far beyond the issue of predicted decant in each of the Witwatersrand’s mining basins. Water security for the GCR, and who will carry the costs associated with the long-term treatment of AMD, have instead taken centre stage. This paper carefully updates the historical record on AMD since the publishing of a GCRO Provocation on the issue in 2010. In doing so, it argues that the way in which AMD has been governed raises a flag around how the political economy of an issue such as AMD should be understood, publicly debated and managed. In particular, it suggests that the governance of an environmental challenge such as AMD is not only about finding a technical solution. The lack of platforms to ensure well-informed public deliberation, especially over such issues as who will pay and how, must be addressed to ensure more equitable and transparent decision-making. In light of the broader mine waste legacy inherited by the GCR, and the strong likelihood of environmental contamination becoming more commonplace in the future, these concerns are not only limited to AMD. They will only grow in importance over time.

This volume is concerned with sites on, or below, which there has been previous industrial activity leading to some permanent effects on the ground. A wide range of problems and impacts makes treatment of contaminated and derelict land a very complex issue. This volume presents the proceedings of Green 2, the second in a four-yearly series of international symposia that discuss aspects of geotechnical engineering intimately related to the environment.

Spoil to Soil: Mine Site Rehabilitation and Revegetation presents both fundamental and practical aspects of remediation and revegetation of mine sites. Through three major themes, it examines characterization of mine site spoils; remediation of chemical, physical and biological constraints of mine site spoils, including post mine-site land-use practices; and revegetation of remediated mine site spoils. Each theme includes chapters featuring case studies involving mine sites around the world. The final section focuses specifically on case studies with successful mine site rehabilitation. The book provides a narrative of how inert spoil can be converted to live soil. Instructive illustrations show mine sites before and after rehabilitation. The purpose of this book is to provide students, scientists, and professional personnel in the mining industry sensible, science-based information needed to rehabilitate sustainably areas disturbed by mining activities. This book is suitable for undergraduate and graduate students majoring in environmental, earth, and soil sciences; environmental and soil scientists; and mine site environmental engineers and regulators.

States in mineral-rich jurisdictions must promote mining as a development industry just as they must protect people and environment from the worst excesses of extractivism. State Governance of Mining, Development and Sustainability explores how the State’s role in facilitating a developmental and sustainable mining industry has been defined. In doing so, this astute book considers the impact of the policies and laws of mineral-rich States themselves, multilateral international governance institutions, industry associations, and environmental justice advocates in the areas of property relations, mineral taxation, environmental management and mine closure.
