COALEX Pry Limited operates two underground steaming coal mines on the western edge of the Sydney Basin near Lithgow, New South Wales. Baal Bone Colliery uses longwall technology for an output of over two million tonne/year while Clarence Colliery currently uses continuous miners and breaker line supports for an output of two million tonnelyear.A computerised geological database and modelling system has been implemented to service these mines routinely, as well as several outlying prospects. The database is constantly upgraded for drillhole information, surveyed spot levels on the surface and underground, quality sampling details, surveyed mine workings and geological mapping. This information is edited on a routine basis, allowing dynamic modelling of key aspects of geology for ongoing operations.
