Future trends for underground thick seam coal mining in Australia

This paper provides an overview of the future for underground thick seam coal mining in Australia. It reviews the available and anticipated mining systems and technologies which may he adopted to mine coal seams of greater than 4.5 m thickness, together with an assessment of the likely technological and operational risks and challenges involved. This overview of mining systems is presented in the context of both current and recently completed research projects funded through the Australian Coal Association Research Program (ACARP). The projects have been joint investigations between The University of New South Wales Mining Research Centre (UMRC) and the Centre for Mining Technology and Equipment (CMTE). Outcomes from the projects have included an appraisal and classification of underground thick seam reserves in Australia and their suitability for each mining method.
