Technical Market Support
Our work in this area is aimed at understanding the properties of Australian coals which impact on market acceptance and emphasising the advantages of our coals over our competitors. The major markets for Australian coals are electricity generation and iron production.
ACARP has also published a series of whitepapers in this area:

Author: Barry Jenkins, Graham O'Brien, H Beath, Joan Esterle | CSIRO Exploration & Mining |
A low-cost imaging system has been developed to characterise coal by accurately determining the reflectance distribution of its constituents. It is a tool that can be used by coal producers, coal users, and commercial and research laboratories. It can be fitted to existing petrographic .... read more |

Author: Graham O'Brien, Barry Jenkins, H Beath | CSIRO Exploration & Mining, Jenkins-Kwan Technology |
A new classification method has been developed that uses imaging techniques for the microscopic characterisation of the individual grains present in ground coal samples. The grains are sorted into five grain classes, based on vitrinite abundances. This system is simpler and less subjective .... read more |

Coals from some Queensland mines cause varying degrees of difficulty due to hangup in rail wagons during unloading at the ports. Jackhammers are currently used at the ports to vibrate the wagons and initiate flow of the coal. Fieldwork, laboratory and pilot scale investigations have been .... read more |
