Maintenance and haulage road studies is
important to keep rolling resistance at the design values
inside a mine site. With variable weather and heavy haulage
trucks travleing down mine haulage roads, road conditions can
change very fast.
Maintenance
The most common way to fix up damage haul roads inside a mine site is the use of a gradder. Almost all surface mines with truck haulage roads will use multiple gradders all shift long to keep the roads in the best possible condition.
Drainage ditches should be checked daily, making sure they are in good condition. Drainage ditches on haulage roads play an important role in keeping the overall road conditions good during storm events.
Soft spots in the road should be removed. Although this disrupts travel time, in the long run it will improve overall cycle times of haul trucks. Removing soft spots improves the rolling resistance of the road in that area. Geo-clothes are placed at the bottom of removed soft spots to keep the material above from sinking again.
Studies
Haulage time studies should be conducted throughout the mine to determine if roads are giving the best optimal times. Through these studies changes to the road grade, rolling resistance, and path can be made to optimize the haulage route. In addition all road building material should be tested for strength to make sure it can withstand the pressure of haul trucks traveling on them.
