Guidelines for metal leaching and acid rock drainage at minesites in British Columbia
The primary objectives of this document are to describe generic requirements and outline common errors, omissions, and constraints with regard to prevention or reduction of metal leaching and acid mine drainage (ML/ARD) at British Columbia mine sites. It begins with background on ML/ARD and guiding principles for the regulation of ML/ARD in the province. This is followed by guidance on ML/ARD prediction, measures to prevent or reduce ML/ARD, general considerations and information and design requirements for specific measures (underwater storage, blending of acid-generating wastes with materials having excess neutralization potential, covering the waste, drainage collection and treatment, and mitigation of specific mine components), and geotechnical and hydrological considerations. Finally, ML/ARD aspects of mine regulation and current ML/ARD research programs are reviewed.
