Highly weathered ground, limited collar options and the need to achieve a desired outcome at the lowest possible cost led to the need to adopt a construction approach that had no established design methodology. The newest ventilation shaft at Mandalay Resources' Costerfield Operations had to be established to a depth of 30 m through poor ground best described as sticky swelling clay', some of which was contained within an old backfilled pit.The ability to excavate a traditional presink was not possible due to limited space and the introduction of men into the shaft was to be avoided due to the associated safety risks and corresponding increase in cost. Piling in conjunction with raise boring and remote fibrecrete application was identified as a possible solution that could achieve the desired outcome at an acceptable level of risk.Construction of the piles was challenging and required continual refinement until an acceptable level of productivity could be achieved. Limitations on concrete delivery was taken into consideration to ensure hole stand-up time was acceptable and re-drills were not required. The adoption of a set process from alignment, drilling, concrete placement and testing ensured the desired design was achieved. Mine operators should consider the use of piling as a method of shaft stabilisation for the portion of raise bored shaft that passes through the weathered zone.The importance of quality control and attention to detail through the entire shaft construction process cannot be underestimated as issues such as insufficient geotechnical investigation, pile and pilot hole deviation, concrete and fibrecrete quality, as well as delays in the application of fibrecrete can place the success of the project at risk.This paper outlines key learnings from a client's perspective with regards to the concept, planning, design, execution and completion of a 3.1 m diameter raise bore shaft through both weathered and highly structured ground at the Augusta Mine.CITATION:Green, S and Austerberry, R, 2014.
