ABSTRACT: The report indicates that best practices for gully layouts have been well recognized, but often poorly applied for many years. Recommendations provided in this report do not attempt to develop any new techniques for gully protection. The objective has been to try to provide a guide to the practices that are best adopted under various geotechnical conditions. All recommendations either are, or have been, successfully applied somewhere in the industry. Based on depth and stress environment, a broad-based recommendation for selection of gully geometry has been developed. Based on numerical modelling coupled to underground observation, optimum widths and spans for each mining layout used at different depths is provided as a non-prescriptive guideline. Recommendations for support are based on local observed ground conditions.

ABSTRACT: A primary output of this project has been the development of an accompanying guidebook, which summarises methodologies for recognising and categorising the occurrence of non-standard or anomalous conditions, and provides guidelines and recommendations to ameliorate the effects of anomalous conditions. The booklet is aimed for use by rock engineering practitioners, planning engineers, safety practitioners and senior production line supervisors. It is intended to be particularly useful to line supervisors who observe underground conditions on a daily basis, and could serve as a training aid.
