This report documents the results of the 2003 spring waste rock storage area seepage survey at Ekati Diamond Mine, conducted in June 2003 in accordance with Water Licence N7L2-1616 requirements. The survey monitored seepage from five waste rock and kimberlite storage areas, measuring field parameters, flow rates, and conducting laboratory analysis of major ions and dissolved metals.
This waste rock and ore storage management plan for the Beartooth Pipe at Ekati Diamond Mine addresses regulatory requirements for managing drainage from ore and waste rock storage areas. The plan includes geochemical characterization results, predicted water quality, and monitoring strategies for the proposed mining operation.
This 2002 waste rock storage area seepage and waste rock survey report for Ekati Diamond Mine documents monitoring of seepage quality, waste rock geochemistry, and thermal conditions at storage areas including Panda/Koala, Misery, and the Coarse Kimberlite Reject Storage Area. The report fulfills Water Licence N7L2-1616 requirements and includes detailed investigations of low pH waters observed since 1999, with findings on sulphate concentrations, acid generation potential, and freeze-concentration effects in seepage.
This Acid/Alkaline Rock Drainage and Geochemical Characterization Plan for the Beartooth Pipe at Ekati Diamond Mine describes predictive testing, operational monitoring, and waste rock management strategies to assess potential environmental impacts from mining waste rock storage. Geochemical testing indicates that biotite granite (>99% of waste rock) has low reactivity, while biotite schist and kimberlite require segregation and encapsulation strategies to prevent acid generation and control drainage chemistry.
This document presents the Acid/Alkaline Rock Drainage (ARD) and Geochemical Characterization Plan for the Pigeon Pipe at the Ekati Diamond Mine, prepared by SRK Consulting for BHP Billiton Diamonds to meet Water License MV2001L2-0008 conditions. The plan describes geochemical testing results, waste rock management strategies, and monitoring protocols for host rocks (biotite granite, diabase, biotite schist) and kimberlite, incorporating adaptive management based on operational experience from the Panda and Misery pipes.
MEND Manual Volume 3 on Prediction is a comprehensive reference document for Canadian mining industry practitioners on sampling, analysis, prediction, prevention, control, treatment and monitoring of acidic drainage from mines. The manual provides information on chemistry, engineering, economics, case studies and scientific data for mine operators, environmental staff, consulting engineers and governments.
This addendum to the approved Waste Rock and Ore Storage Management Plan (February 2000) presents updated geological, geochemical, and characterization data for the Fox Pipe at Ekati Diamond Mine, along with refinements to waste rock management strategies based on site experience and adaptive management practices since 2000. The plan describes geochemical testing results, monitoring methods, and waste rock storage management strategies incorporating permafrost formation, encapsulation of reactive kimberlite, and toe berm construction to control runoff.
A comprehensive catalog of MEND (Mine Environment Neutral Drainage) program reports and resources available for purchase, covering research, prevention, control, and treatment methods for acid mine drainage from mining operations, with ordering information for the MEND Secretariat.
This is a technical short course handout on acid rock drainage (ARD) prevention and control presented by Mehling Environmental Management Inc. to DIAND on April 24, 2002. The document outlines ARD causes, prediction methods, and various preventive and remedial mitigation strategies including waste rock blending, layering, alkaline addition, underwater disposal, and chemical treatment, with case studies and laboratory evaluation approaches.
This DIAND technical short course handout from Mehling Environmental Management Inc. presents comprehensive theory and prediction techniques for acid rock drainage (ARD), covering ARD generation mechanisms, prediction methodologies (static and kinetic testing), field monitoring approaches, and mitigation strategies for mining and construction projects.
A comprehensive technical short course delivered by BGC Engineering Inc. on geotechnical engineering applied to mine waste, covering soil mechanics, permafrost terrain, tailings dam design, construction methods, monitoring instrumentation, and case histories of dam failures including Omai (1995), Los Frailes (1997), and permafrost-related failures.
A five-day technical short course organized by DIAND from April 22–26, 2002, covering geotechnical engineering, permafrost design, acid rock drainage prediction and control, and risk assessment in cold environments, delivered by experts from BGC Engineering, Mehling Environmental Management, and Oboni Associates.
Notice of a 5-day training session on environmental review of mines to be held April 22–26, 2002 in Yellowknife, covering geochemistry, water quality, tailings management, and risk assessment methodology for northern mining projects.
Technical presentation on soil cover design strategies for mine waste in cold climates, including barrier covers, store-and-release systems, and frozen covers that utilize below-freezing temperatures to restrict acid rock drainage generation.
A presentation handout by Mehling Environmental Management Inc. on soil cover design and application for mine waste management, covering conceptual modeling, design steps, field testing, and construction methodologies to prevent acid rock drainage through water and oxygen limiting covers.
A handout presenting a framework for applying risk assessments to acid rock drainage (ARD) at mining operations, including hazard identification, probability and consequence evaluation, and case studies of mitigation measures for collection ditches, treatment systems, and waste rock management.
This 2001 waste rock storage area seepage and waste rock survey report documents monitoring results from the Ekati Diamond Mine in compliance with Water Licence N7L2-1616, evaluating seepage quality, waste rock geochemistry, thermal conditions, and groundwater characteristics at the Panda/Koala, Misery, and Coarse Kimberlite Reject storage areas.
This 2001 waste rock storage area seepage and waste rock survey report documents monitoring results from the Ekati Diamond Mine, including characterization of seepage quality, geochemical testing of waste rock from Panda, Koala, and Misery pits, thermal monitoring, and groundwater investigation conducted in compliance with Water Licence N7L2-1616. The report presents findings on acid-generating potential, seepage water types, and environmental impacts from multiple waste rock and kimberlite storage areas.
This preliminary waste rock storage management plan for BHP Billiton's Pigeon Pipe kimberlite mining development describes geochemical testing, thermal and hydrological modeling, and adaptive management strategies to minimize environmental impacts from waste rock disposal, incorporating operational experience from existing Ekati waste rock storage areas.
This preliminary waste rock storage management plan for BHP Billiton's Beartooth Pipe development describes geochemical testing, site characterization, and management strategies for waste rock disposal in the Panda/Koala waste rock storage area. The document concludes that approximately 99% of waste rock (biotite granite) has low reactivity, while small components of biotite schist are potentially acid-generating and will be segregated and encapsulated with non-reactive granite to ensure freezing conditions.
