Abstract. ADTI is a coalition of Federal and State agencies, industry, academia, and consulting firms working together to address a range of issues dealing with the technical problems of predicting and controlling acid drainage. The ADTI is organized into two major groups, a coal mining sector and a metal mining sector. The Coal Mining Sector (http://wvwri.nrcce.wvu.edu/ADTI) is organized into two primary working groups, one on prediction and the other on avoidance and remediation methods. Recently, the Coal Mining Sector met to review its accomplishments, the status of ongoing studies, and to develop a five-year plan for future studies and efforts. This paper discusses the planned activities of the Coal Mining Sector of ADTI and future research needs related to acid drainage.Additional Key Words: acid mine drainage, acid rock drainage, coal mining sector.
In 1995, the U.S. Office of Surface Mining (OSM) and the National Mine Land Reclamation Center (NMLRC) joined with the Interstate Mining Compact Commission, the National Mining Association, academia, and other Federal agencies to form the Acid Drainage Technology Initiative (ADTI). The ADTI partnership seeks to identify, evaluate and develop "best science" based practices to prevent new acid mine drainage sources and eliminate existing sources. The ADTI partnership developed a management structure to oversee the program and developed action plans to address key technical areas. The ADTI organization consists of a coal mining sector, a metal mining sector and a secretariat, overseen by an Operations Committee. The coal mining sector of ADTI is divided into a prediction working group and an avoidance and remediation working group to implement and coordinate the research strategy. This paper summarizes the results of the coal mining sector efforts since the completion of the avoidance and remediation, and prediction handbooks in 1998 and 2000, respectively, and the status of current activities. The activities have included field verification of acid drainage predictions using acid-base accounting, monitoring and follow up evaluation of acid mine drainage passive and in-situ treatment systems, developing standardized kinetic testing protocols, flooded underground mine pools, and issues related to elevated selenium in streams associated with surface mines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
