Operation and Monitoring of Mine Dumps Interim Guidelines

This document presents guidelines for operating and safety procedures for mine dumps based primarily on a literature review, discussion, judgement and existing dump operations manuals provided by the mine operators in B.C. General areas of responsibility are defined and recommendations are made on dump loading rates and allowable crest movement rates, but safe limits on such aspects must be developed for each site. General requirements for monitoring are also presented, including crest movement, slope movements, toe movements, internal deformations, dump saturation levels, and foundation pore pressures. The various types of monitoring equipment are also described and procedures are given for assessing, reporting and responding to monitoring results. A detailed mine dump failure reporting format is suggested.
