A

Activities

The types of tasks that are completed as part of the mining schedule. In MineSched, mining is the only mandatory activity.

Actual Haul Paths

The path that is followed from the initial source of a material to its final destination. The actual haul path includes the:

• ramp haul path
• bench haul path
• path the material travels before it arrives at the bench haul path
• path the material travels between the bench haul path and the ramp haul path
• path the material travels from the ramp haul path to the final destination

Aggregate

The sum of a defined range of values.

Animation

Displaying information about the schedule graphically, using a method that gives the illusion of movement.

Attribute

A field in a model that defines a value for a particular feature of the model.

Average

The value determined by summing a range of values and dividing by the number of values. The average used in MineSched is the mean average.

B

Background Value

A baseline value that is applied when a specific value is not defined.

Bench Haul Paths

The paths that is it possible for trucks to travel on a bench.

Bench Polygon

A polygon that defines the shape and location of a bench.

Blending

Block Model

A representation of a geological formation where the formation is defined by the shape of a three-dimensional grid of blocks and the data stored in the attributes of the blocks.

C

Calendar

A definition of the time in which resources can be working. In MineSched, Calendar also refers to the tool that allows you to select dates using a calendar widget.

Capacity

The maximum amount that something can contain or perform.

Case-Sensitive

A field is case-sensitive if letters are treated as different characters when they are uppercase or lowercase. For example, in a case-sensitive field "NAME" is considered a different value to "name".

Charts

Graphical representations of data. In MineSched, charts are available in the Define Geology > Validate, Setup Development > Evaluate, Setup Schedule > Evaluate, and Create Schedule tabs.

Collection

Connection

A join between two or more items. To schedule correctly, MineSched requires that headings are connected correctly and haulage paths are connected correctly.

Constraint

A filter that is applied to data so that only the data that fits specified criteria is available to work with or view.

Coordinates

A set of measurements that specify the position or orientation of a point. The number of coordinates in the set depend on whether the point is:

• on a 1-dimensional line : one coordinate
• on a 2-dimensional plane : two coordinates
• in 3-dimensional space : three coordinates

Cutoffs

An arbitrary value above or below which data is not considered. Multiple cutoffs can be applied to data to create multiple data groupings, for example low, medium, and high grade.

D

Data Grids

The grids in which you enter data to define the scenario. Many data grids can be replaced by a Spreadsheet View.

Density

• browse for data
• use the Wildcard Expression Builder
• use the Named Wildcard Builder
• use the Event Builder
• use the Visibility Constraints form
• use a Calendar

Event

A feature of the schedule for which it is possible that the date is not known until the schedule is run. MineSched provides an Event Builder to allow you to set rules that take effect when an event occurs rather than on a particular date. For example, to define that mining does not start in location B before mining is complete in location A.

Perspective

A method of representing a three dimensional object in two dimensions. Perspective representation uses parallel projection, where the representation appears as it would when viewed in three dimensions by the human eye. That is, the dimensions of the object along the line of slight are relatively shorter than the dimensions of the image across the line of sight.

Polygon

String Model

A representation of a geological formation where the formation is defined by the shape and data stored in line structures.

Successor

An event that cannot occur until another event has occurred.

Suffix

Swell

The change in volume of a material due to it undergoing a process. For example, the swelling of rock because of blasting.

T

Temporary Spreadsheet View

For data grids with temporary spreadsheets, the spreadsheet appears as a form that you can use to define data that is entered in the data grid. When you close the window the data is filled into the data grid. You can use formulas while you are filling in the temporary spreadsheet, but the formulas are lost when you close the window. You access the temporary spreadsheets by clicking the Edit in spreadsheet view icon on the relevant data grid.

Threshold

A minimum or maximum value below which or above which something takes effect.

TKM

Tonne kilometres. This is a measure of the mass of material moved multiplied by the distance that the material is moved. For scenarios using metric measurements, the tonnes kilometres of material moved. For scenarios using imperial measurements, the ton thousand feet of material moved. The TKM is calculated as the mass of material moved multiplied by the distance, divided by 1000.

Tolerance

W

Wildcard Character

A character that can be substituted for any of a defined set of possible characters.

Wildcard Expression

A word or statement that includes one or more wildcard characters. MineSched provides a Wildcard Expression Builder in many data grids to make it easier to construct a wildcard expression that captures the items for which you are interested in setting rules.
