Mine haul road design and road safety

What can be done to design and build mine

haul roads to a good and safe standard that

recognises the need to apply national road

building standards and practices

1

Recognise what a good road should look like

Understand the profile of the road

Provide drainage for water to run off road and

disperse

5

Superelevation on curves as required


6/21



6

Consider intersection design looking at

number of conflict points

Location of intersections, not on curves or crests

Avoid Y intersections

Re-align Y intersections to simple T or

staggered T intersections




T intersection at 90 degrees to through road

Rationalise the number of intersection roads




Adequate forward sight distance on crests

Sight distance on forward curves

Post speed limits along haul roads, be consistent




Good maintenance makes safer roads

off the road

Install guide posts at regular intervals to providedelineation of haul road, must be able to see a

minimum of two pairs along the road at any

one time.

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.
