Coalfield Geology Council of New South Wales


The Coalfield Geology Council of NSW is the representative body for geologists working in the coal industry. The Council was originally formed in 1961 as the Standing Committee on Coalfield Geology of New South Wales. Over the past 50 years the Council has been a driving force in defining the stratigraphy of NSW, writing standards and codes for exploration and estimating resources, and promoting the advancement of technology in geological exploration.

The aim of the Council is the advancement of Coalfield Geology of New South Wales by activities including among other things:

  • Providing a forum for the sharing of information on the geology of the coalfields of NSW and techniques for the understanding of the contained coal resources and their exploration and extraction
  • The provision of effective industry/government consultation on all matters involving coalfield and mining geology
  • Promote liaison with other Australian coal geology groups with a view to the establishment and revision of codes, standards and guidelines for exploration and mining geology
  • Exchange of ideas on geoscience techniques and terms employed in coalfield geology with a view to standardisation
  • The appropriate distribution of the results of the Council’s considerations and activities

Membership is open to all geoscientists interested in coal geology in the coalfields of NSW. Members include mine and exploration geologists, consultants, retired professionals, students, academics, CSIRO and government employees. Members can choose their level of engagement with the council, for example, by email, or attending quarterly meeting or symposia. Please contact for information about becoming a member.

The Coalfield Geology Council of NSW has a strong history of encouraging professional development for geoscientists. The CGC presents one day workshops to provide high level, cost effective training from industry leaders. Workshop topics include Coal Quality, Geophysics, Geotechnical, Regional Geophysics, Hydrogeology and Geostatistics.

Past Events & Activities

26-27 November - Coalfield Geology Council of NSW & ALS Coal Services Coal Quality Course
Presenter: Adrian Reifenstein, Business Manager, Coal Technology & Exploration, ALS
Part 1 provides a framework for understanding coal from a rank, type and inorganic impurities perspective.
Introduction to Coal (1.5 hr)
Part 2 provides an overview of the correct process for measuring coal quality. This includes a review of the theory and practice of correct sampling and sample preparation. It provides an overview of a broad range of coal analytical tests and discusses their applicability and accuracy. This course focuses on coal test required by geologists. It also provides an overview of the processes that laboratories perform to ensure that they laboratory systems are controlled.
Coal Sampling Theory and Practice (2.0 hr)
Coal Sample Preparation (0.25 hr)
Coal Analytical Tests (2.0 hr) 
Laboratory Process Control (0.75 hr)
Part 3 provides a brief overview of the coal beneficiation processes occurring in a coal mine and a coal preparation plant and links these processes to coal core exploration programs.
Mining and Coal Preparation Practices impacting on Product Coal Quality (1.0 hr)
Large Diameter Core Programs simulating Product Coal Quality (1.0 hr)
Coal Sales Process (1.0 hr)
Part 4 links coal quality to end-use performance in coal-fired power-station and ironmaking processes and ultimately the price coal achieves in the marketplace
Coal Utilisation in Power-stations and Steelworks (1.5 hr)
Part 5 provides a half day tour of the ALS laboratory
Location: ALS Coal Services, 2 Spit Island Close, Steel River Industrial Estate, Mayfield West, NSW 
Time: 8.30am - 4.30pm
PPE: PPE will be provided for the laboratory tour. Closed in shoes, long sleeve shirt and long pants are recommended
for the second day (laboratory tour). Steel capped boots are not required.
