Development of rehabilitation plans for acid rock drainage control at two closed underground mines Brodie, M. John; Chapman, John T.

Abstract

Underground mines have long been recognized as sources of acid rock drainage (ARD). Point discharge of low pH and metal laden solutions occurs at portals and shafts. Rehabilitation is often required to mitigate the chronic long-term effects of ARD from underground mines. This paper presents the methodology used in the development of rehabilitation plans for ARD control for two closed underground mines in B.C., namely the Tulsequah Chief Mine and the Baker Mine. Factors that influence the rehabilitation options for a given site are discussed. A brief summary of the conditions observed at the two mine sites and the proposed rehabilitation plans are presented. Control of ARD from underground mines may be achieved by flooding the mine through the construction of concrete bulkheads. Key Words: acid drainage, site assessment, decommissioning, underground mine
