The results show that the rate at which the rotation capacity decreases with increasing axial compression is dependent on the aspect ratio of the section, but further finite element simulation is required to investigate the effect of geometric imperfections

systems offer inherent labour, energy and environmental benefits to deep pit metalliferous mines.
However, before such systems become commonplace, a number of barriers must be overcome.
This paper outlines a number of commonly perceived barriers to FMIPCC application, together
with a number of suggested solutions. The paper advances a design approach for specifying
FMIPCC systems for deep pit metalliferous applications. A novel FMIPCC configuration is
advanced using a hydraulic excavator in backhoe configuration. Because of the requirement to
minimise belt extensions, a mine planning approach is presented based on a series of parallel and
radial belt conveyor moves.
The FMIPCC system does not fully replace truck-shovel systems. In the proposed mine plan,
sinking is undertaken with truck-shovel systems using a series of box cuts, whereas pit ‘widening’
activities are accomplished via the FMIPCC system. Because of inherent differences in mine
sequencing, the net present value derived from the FMIPCC mine will differ markedly from that
derived from traditional, nested-pit, truck-shovel mining approaches. Therefore, any comparison
of the FMIPCC and truck-shovel approaches must take into account radically different mine
planning approaches.
