Control Of Mine Drainage From Coal Mine Mineral Wastes

A project has been underway which attempts to demonstrate practical means of abating pollution from coal mine mineral wastes. The site included a refuse pile occupying approximately 40 acres and a slurry lagoon complex of 50 acres. In the report, the characteristics and acid formation rate of the refuse pile are described. The average rate of acid formation for this refuse pile is 198 pounds of acidity, as CaCO3, per acre per day. Acid contribution from the slurry lagoons was not determined but appears to be negligible. As an abatement measure, a number of experimental vegetative covers were tested. Grass was successfully established with and without the use of topsoil, weathering well for one year. The long-term effects of establishing a grass cover directly on the refuse without the use of topsoil are not known at this time.

Basics of Metal Mining Influenced Water is a must-read for planners, regulators, consultants, land managers, students, researchers, or others concerned about the environmentally sound management of metal mine wastes and drainage quality. The first of a series of six handbooks on technologies for managing metal mine and metallurgical process draining, this book offers a unique, comprehensive perspective on the subject. Unlike other texts that focus primarily on acid drainage from coal mines, the authors examine both acidic and neutral pH waters that can be hazardous to the environment. Planning a new mine in today s increasingly contentious regulatory and political environment demands a different philosophy. Basics of Metal Mining Influenced Water takes an innovative, holistic approach by considering all aspects of the mine life cycle, including closure. Written by a team of experts from state and federal governments, academia, and the mining industry, Basics of Metal Mining Influenced Water also discusses the major physical and chemical relationships between mining, climate, environment, and mine waste drainage quality. The authors have included an extensive glossary defining hundreds of technical terms for easier reading and understanding.

Mitigation of Metal Mining Influenced Water is the "how to fix it" volume in a series of six handbooks on technologies for managing metal mine and metallurgical process influenced water. Unlike other texts that focus exclusively on acid drainage from coal mines, this comprehensive series examines both acidic and neutral pH waters from metal mining and metallurgical processes that may impact the environment. The authors take a holistic approach by considering all aspects of the mine life cycle, from planning and design to closure. In this book you'll learn how mining influenced water concerns can be prevented or reduced by disrupting the geochemical relationship that contributes to the release of metals and/or acidity. Industry experts provide insights into understanding a mine's physical environment and how it can influence waste and drainage quality. They outline key issues designers must address, including involving stakeholders who may be affected long after the mine closes. Case histories offer valuable planning and design considerations by illustrating what works and what doesn't. You'll also benefit from a thorough examination of mitigating technologies in a host of mining and processing situations, as well as the latest arsenal of waste treatment options. Mitigation of Metal Mining Influenced Wateris a must-read for planners, regulators, consultants, land mangers, students, researchers, and others concerned about the environmentally sound management of metal mine and metallurgical processing wastes and drainage quality.
