What can you do to improve your haul roads? Train design personnel in elements of traffic
engineering
Design haul roads that are fit for purpose, simple
intersection design
Build separate HV and LV roads
Conduct road safety audits regularly
Provide adequate sight distance through curves and
crests
Post realistic speed limits
Use Australian Standard signs
Provide good delineation20

Conclusions; Build and maintain mine haul roads to a consistent standard to
reduce the risk of incidents
Simple application of road design elements and consistent road
signs and delineation will make this a reality.
It is now becoming widely recognised in mining that the roads
are an important asset to the mine and without them the
business is not as profitable or efficient.
Following the guidance given above will lead to a simpler andsafer mine road network for all road users. This intern will lead
to fewer incidents, increased efficiency, and profitability of the
mine operation.
