Formatted abstract
Production dozing has been described as continuously pushing large volumes of waste over a short distance (Hays, 1990). Production dozing has been used as a method of overburden removal since the 1960s. Manufacture of large scale dozers during the 1990s saw production dozing re-emerge as a legitimate mining method.

Under the right mining conditions production dozing is a viable alternat ive to dragline and truck and shovel stripping operations. Tarong Coal, an opencut thermal coal mine located in Southeast Queensland has seen production dozing as a means of increasing overburden removal capacity and reducing overall mining costs. To fully understand production dozing a trial was planned for May and June 2003.

The overarching aims of this trial are to establish actual production rates and actual costs for production dozing at Tarong Coal. This thesis details the process followed for implementing the production dozing trial and discusses the results of this trial. Initial discussion works through a literature review that highlights varying methods for production dozing as well as factors affecting production dozing.

The design process employed at Tarong is discussed in detail. Areas of particular interest are the integration of a Hitachi EX3600 for highwall scaling and the use of the 3D Dig program for producing dozing plans. Dozer productivity and costs are modelled using the Cat Handbook Method.

Actual production rates and indexed costs for the production dozing trial are calculated and presented in this report. Operator observations are used to carry out an analysis of blast performance. Dozer performance issues such as availabilit y, utilisation and other key performance indicators are calculated and discussed. Feedback from the operators and project supervisor is collated with relevant comments noted. Finally, recommendations for improving future production dozing operations at Tarong are given.
