C1005301/02/2003
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

 

Development of a Coal Handleability Index

Investigation into Problems of Discharging Queensland Coals from Bottom Dump Rail Wagons

Get Report
C1006101/11/2002
Author: Graham O'Brien, Mike O'Brien, Bruce Firth, D Nemeth, J Graham, S Gnanananthan | CSIRO Exploration & Mining, CSIRO Energy Technology, Queensland Rail

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
