The beginning of this page is intended to set the stage so that common ground exists for readers. Mass Haul is the movement of material. Typically dirt or rock. Mass haul calculations are made in order to determine the logistics of moving materials: how, when and with what. A mass haul analysis is done with a mass haul diagram and a mass haul report. The diagram is a graphical representation of the movement of materials and the report is has the details of amounts, ordering and stations locations. Note that mass haul analysis is most commonly done for road construction.

Figure 1:

A Mass Haul Diagram in its simplest for is a line drawn on x-y axis (Figure 1). One axis is the material volume and the other axis is the station location or distance along the road. The orientation can be portrait or landscape. The line drawn on the coordinate system describes the accumulation of the volume of material as one progresses down the road. If the line is moving up it is in a CUT situation and material volume is increasing. If it is moving down it is in a FILL situation and material volume is decreasing. Note that it is possible to have a negative volume. That means the project needs material.

Figure 2:

When the mass haul line is above a zero (0) volume the project is in a general CUT condition. When the mass haul line is below a zero (0) volume the project is in a general FILL condition. If you draw a line thru the mass haul line at a constant volume any 2 points where the constant value and the mass haul line intersect describe a balance of materials: an equal amount of cut and fill material. So in Figure 2 points A-B, A-C, A-D describe a balance of material. Note that is can be any 2 points so C-B also describes a balance.
