MAGNET Project: Planning in Mass Haul View

Overview

The Mass Haul View shows quantities and the whole mass haul plan.

  • The road line stations are horizontally in the middle of the view, cuts are above the road line, and fills and other quantities are below.
  • The boxes representing quantities are filled with a hatched color when their hauls have not been planned and in a solid color when they have. 
  • Intersections are shown in the upper edge of the Mass Haul View.
  • The lower edge of the view shows borrow pits, disposal areas, and crushing plants.

Several locations can be displayed at once by creating a New location layout in the Location drop-down menu. Add locations under the Layout tab.

Showing hauls

  • When hauls have been calculated, the mass haul plan is shown by right-clicking on a task and selecting Show hauls.
  • All hauls are shown by right-clicking an empty part of the view and selecting Show All Hauls.
  • Hauls are filtered according to task types, locations, haul quantities, or haul time spans by using filters.

Surplus of unsuitable material

  • Is it possible to use the material in secondary structures? Can it be refined?
    • Open the Quantity type properties window for the chosen material.
    • Navigate to the Suitabilities tab and adjust suitabilities by adding new accepted destination types to haul the material to.

 

  • Is it cost efficient to turn soil replacements into strengthening methods that don’t produce unsuitable surplus material?
    • Create a disposal/waste area. From a mass haul point of view, the disposal/waste area’s best location is as near to the surplus as possible.
    • Check the surplus amount and location from the unhauled mass report.
    • Recalculate the mass haul plan based on the changes.
    • Inspect the changed mass haul plan from the Mass Haul View.

Surplus of suitable material

  • Is it possible to sell the material?
    • Create a disposal/waste area in a location that would simulate the hauls of sold material.

 

  • Can the construction designs be edited/optimized to form less surplus?
    • For example, it is possible to lift the grade line or adjust the slope angle to reduce surplus/excess volumes.

 

  • Is it possible to use higher quality surplus materials to improve the fill quality and, as a result, get a better end result on the project?
  • Can rock material be crushed for usage in aggregate fills?
    • Add a crusher from the template or create a new crushing plant. The location is often optimal close to a suitable quality rock excavation or where there is room to store the aggregate.
    • Create a disposal area. From the mass haul point of view, the best location for the disposal area is as near the surplus as possible.
    • Check the amount and the location from the unhauled mass report.
    • While adding a disposal area, edit the type to be correct on the first tab and the location and size from the second tab.
    • Recalculate the mass haul plan based on the changes.
    • Inspect the changed mass haul plan from the Mass Haul View.

Deficit of suitable material

  • Can the construction designs be edited/optimized to form less deficit? For example, is it possible to lower the grade line or adjust slope angles?
    • This is possible with the aim being to get out extra from the cuts near the deficit.

 

  • Is it possible to reduce the deficit by changing the structural solutions? For example, is it possible to replace fill requirements? This could mean changing soil replacements to ground stabilization or noise reducing banks/berms to constructed noise fences.
  • Is there a lack in the aggregate fills? Can rock material be crushed for usage in aggregate fills?
    • Add a crusher from the template, or create a new crushing plant. The location is often optimal close to a suitable quality rock excavation or where there is room to store the aggregate.
    • Create a borrow pit if missing material can be bought or otherwise supplied from a nearby location.
    • Recalculate the mass haul plan based on the changes.
    • Inspect the changed mass haul plan from the Mass Haul View.
