English: A mass haul diagram showing land mass being hauled to land fills and rock mass being hauled to rock fill. The road line station number goes from left to right. This is a simple example of a cut and fill operation in civil engineering earthwo
A mass haul diagram where land and rock cuts are hauled to fills Fill construction in 1909 Cut and fill software: view from above. In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments to minimize the amount of construction labor.
The goal of mass haul planning is to determine these amounts and the goal of mass haul optimization is to minimize either or both. [ 2 ] Now they can be performed with a computer and specialized software , including optimisation on haul cost and not haul distance (as haul cost is not proportional to haul distance).
The software has a Windows graphical user interface and it includes views such as the Gantt chart, resource graph, mass haul diagram, map view, time distance chart and text reports. [ 9 ] [ 2 ] The time-location method has strengths compared to Gantt charts and traditional scheduling.

has units of mass, and it is the only parameter in the Standard Model that is not dimensionless. It is also much smaller than the Planck scale and about twice the Higgs mass, setting the scale for the mass of all other particles in the Standard Model. This is the only real fine-tuning to a small nonzero value in the Standard Model.

Mathematically, mass flux is defined as the limit =, where = = is the mass current (flow of mass m per unit time t) and A is the area through which the mass flows.. For mass flux as a vector j m, the surface integral of it over a surface S, followed by an integral over the time duration t 1 to t 2, gives the total amount of mass flowing through the surface in that time (t 2 − t 1): = ^.
