Acid and Metalliferous Drainage (AMD) or Acid Rock Drainage (ARD) represents the single biggest environmental issue facing the mining industry worldwide.  The issue can become particularly problematic post mine closure.  Unfortunately, treatment of mine drainage in perpetuity is becoming a more routine solution to this problem.  The purpose of forums such as the Australian AMD Workshop is to discuss, devise and implement proactive strategies for minimising and avoiding AMD during mining operations, so that unpalatable options such as treatment in perpetuity can be avoided.

The University of Queensland's Sustainable Minerals Institute (SMI) has been actively involved in the design and organisation of the Australian AMD Workshops for close to 20 years.  This forum is designed to bring together mine planners, engineers and environmental specialists from mining companies, mining regulators, specialist geochemical and geotechnical consultants, researchers and graduate students.  Together, these stakeholders are able propose, design, test, implement and document solutions that can then be prescribed by regulators.

In order to help recruit and train new members to this technical cohort, as well as introduce the latest thinking, concepts and technologies to experienced members, SMI has been providing AMD short courses the day preceding the workshops for many years.  The short course is designed to introduce participants to all of the key steps required to understand, characterise, classify and manage AMD.  A strong focus will be on management measures for dealing with water quality issues from all of the routine sources.  Key AMD generating domains typically include waste rock piles, tailings storage facilities, heap leach pads, ore stockpiles, concentrate stockpiles, opencuts (walls and floors) and underground mine voids.  Participants can expect to come away with a significantly improved understanding of their options for assessing and managing AMD risk.

The short course is presented by 11 internationally recognised AMD specialists, who have been working in the field for many years.  Each is familiar with all aspects of AMD but has been asked to focus on one topic only for the course.  The final session of the short course is dedicated to answering any questions you may have regarding the course content, or any query that is pertinent to clarifying an existing AMD issue.  To help answer your questions, feel free to bring along some of your data if you are happy to share it with the group.
