Legacy of Coal Mining to Groundwater Environment (Facilitator - Dr. Kai Witthüser)

  • 00m 00s
  • NQF LEVEL 8

SERVICE PROVIDER: DELTA-H & WATER BUSINESS ACADEMY
COURSE DURATION: 1 DAY
CPD ACCREDITATION (ECSA & SACNASP): 1 CPD Point

 

BACKGROUND
Mine water management is a broad topic covering a range of specialist sub-disciplines. In this case, mine water management will focus on groundwater, surface water and process water management within the mining environment, on the water management aspects associated with the varied mine residue deposits as well as on the regulations that govern the use, storage, management, etc. of the water resources.

OBJECTIVES
The main objective of the varied modules on Mine Water Management is to improve ‘water resource management across the mining environment’ and to apply knowledge as well as implement preventative and mitigation programmes in an integrated manner.
The specific objectives of this module are;

  • To characterise, quantify and report the potential impacts of mine closure on the quality and quantity of groundwater (& surface water) resources on the mine site and in the vicinity of a mine.
  • To characterise and describe the post closure rebound of the groundwater table (including potential decant) and the associated evolution of post-closure water chemistry.
  • Management options for the post closure rebound of the groundwater table and chemistry.

SHORT COURSE CONTENT

  • With the limited time left before many of South African Coal Mines reach the end of life of mine, closure planning and costing comes sharply into focus. A major component of mine closure and post closure liabilities relates to groundwater impacts in the form of quality impacts from mine residue deposits (MRDs) or backfill material, quantity impacts due to changed surface topographies and structures with changed recharge values and patterns and impacts on groundwater flow, ranging from changed aquifer properties and flow directions to potential surface decant. These complex, long-term impacts require a sound theoretical and practical understanding of the geochemical processes driving acid rock drainage ARD) as well as the hydrogeological processes driving recharge, seepage from MRDs and decant.
  • This one day course will facilitate a better understanding of these processes by providing an overview of static and kinetic ARD assessment methods and subsequently developed geochemical models for coal mines, including their limitations. Changes to groundwater recharge and flow regimes in open cast and underground mining environments will be elaborated based on saturated (Darcy and Bernoulli equation) and unsaturated (Richards equation) flow processes as well as site specific examples. Potential mitigation measures for post closure groundwater impacts will be developed in discussion with the course participants.

 

TARGET AUDIENCE
This short course is intended for practitioners (i.e. professionals) with minimum 3 years’ experience including;

  • Water Resource Practitioners & Managers (eg. Engineering and Environmental staff that are associated with the mining and related consulting industries).
  • Staff of Governmental Departments (eg. Department of Water and Sanitation, Department of Environmental Affairs etc.)
  • Practitioners that are qualified in associated / related disciplines.

DELIVERY MODES
A hybrid / blended approach to offering the short learning programmes of WBA will be implemented. Theoretical and selected practical / case study modules will be offered either through contact training sessions and / or by means of virtual on-line sessions.
Water Business College (WBC) will apply the latest technology and software (where applicable) to effectively / optimally deliver the knowledge and practical modules.

ENTRY REQUIREMENTS
A recognised Bachelor’s Degree at NQF Level 7 or above in an appropriate / relevant physical scientific discipline.

RECOGNITION of PRIOR LEARNING (RPL):
The provider recognises and will meet the national requirements for RPL. RPL applications will be assessed for the following:

  • An applicant’s informal learning or non-accredited formal studies are assessed as being equivalent to the prerequisite qualification.
  • Work experience; a minimum of 3 years’ experience within the industry in conjunction with the academic record of the candidate.
  • The implementation of advanced standing in instances where the candidate does not meet the minimum entry requirements.
  • Relevant modules / short courses that have been successfully completed at other accredited Higher Education Institutions where the modules / short courses are equivalent in content and standard.
