Geoenvironmental and Geotechnical Issues of Coal Mine Overburden and Mine Tailings (Springer Transactions in Civil and Environmental Engineering)

This contributed book edited by leading global experts focuses on the geoenvironmental and geotechnical issues of coal mine overburden and mine tailings and its unengineered dumping. It aims to provide knowledge-based information for diverse readers to assess, monitor, and manage coal mine overburden and mine tailings in various engineering applications while highlighting efficient solutions to reutilize the waste and conserve natural resources leading to sustainable development. The content also assesses mine backfilling, techniques to stabilize mine tailing storage facilities, mineral carbonation of mine tailings, landfill liners and barrier systems, reclamation of coal mine overburden, and geochemical, microbial, and environmental sustainability assessment, among others. This book is a useful resource for those in academia and industry.
