AMC lists the following as the factors influencing haulage method selection:
Single decline truck haulage allows a great deal of flexibility and is cost effective, particularly for short life operations.
Furthermore, there is now great potential to automate truck haulage on ramps.
In mines using trackless equipment, this should always be a priority, especially with decline haulage. However, it is important to note that road maintenance becomes more difficult and costly as the gradient is increased, particularly where there is water inflow onto the roads.
AMC has developed a multi-use simulation software programme which is capable of modelling real life situations, including truck and shaft haulage systems.
Sandvik Tamrock's Toro engineers consider that mines up to 2 Mt/y operating at depths of at least 500 m, sometimes more, should consider truck haulage as an economic alternative.
