Applied Structural Geology In Cut And Fill Stoping Operations At Mount Isa

A systematic approach to the collection, presentation and application of structural geology data is employed in the extraction of narrow en echelon Ag-Pb-Zn orebodies by rut and fill stoping at Mount Isa. The aim is to locate, document and predict areas of adverse ground thereby enabling adequate ground support to be installed in advance of production mining. The important structural features are identified and their relevance illustrated by case histories of previous failures. The methods of collection, documentation and application of data are discussed.
