-
1. The proportion of time that a piece of equipment is available for use. 2. The proportion of the solid or block that is available to be mined.
-
A type of process node that can be added to the material flowchart in Strategy setups. It accepts ore directly from pits and stockpiles and allows the calculation of saleable product and revenue generated in the schedule. Beneficiation groups streamline the handling of the obtained ore material, and help to manage the waste tailings, which also result from the beneficiation process.
-
In Origin Blocks, a rectangular prism representation of discrete volume with homogenous grades. Block models are a collection of these blocks, and are used to represent ore bodies or pits.
-
In Evolution, the minimum grade required for material to report to a particular process or destination.
-
A rule that defines the mining order of solids by specifying which material must be extracted before other material becomes accessible.
-
An exit point from the road network to a destination such as a mill, stockpile, waste utility, or virtual waste dump.
-
A hybrid pit model that combines a solid model and a block model, using solids to generate mining dependencies while retaining the detailed data resolution of block models.
-
Configuration settings that control how the Evolution optimisation engine runs calculations, including solver behaviour, optimisation limits, and scheduling options.
-
The part of an Evolution haul network that is between a source waypoint (typically placed at the entrance to a pit) and the destination waypoint (typically placed at the entrance to a mill, stockpile, or waste dump).
-
A path flagged so that an internal waypoint acts as a strict control point. Material that does not satisfy the waypoint’s filter conditions cannot pass through the waypoint to reach other destinations. This setting applies only to paths from internal sources.
-
A source waypoint flagged so that material matching its filter must pass through that waypoint, even if other source waypoints could also accept the material.
-
A point in a road network path that trucks are required to pass through.
-
A mandatory constraint that Evolution must satisfy when generating a schedule.
-
See road network.
-
See road network.
-
The portion of an Evolution haul network located inside the pit, extending from the defined dig locations—represented by the 3D solids or blocks that mark where material is excavated—to the source waypoints at the pit exit. It includes all roads and ramps that lie within the pit boundaries.
-
A point in a road network path marking an in-pit crusher that reduces the size of the chunks of mined material by crushing them into smaller chunks directly in the pit. In-pit crushers are available only in Origin Blocks setups that include at least one in-pit crusher.
-
A source waypoint flagged so that Evolution treats it as the boundary between the in-pit and ex-pit haulage paths.
-
A 3D representation of a pit, dump, or stockpile that includes associated volumes and grades, represented as either a block model or a solid model. Models consist of a number of mineable units that share the same attributes.
-
A Strategy setup with two or more primary elements defined, used when different mill processes accept different combinations of elements.
-
The goals used by the optimisation engine when generating a schedule, such as maximising net present value or achieving blending requirements.
-
The part of an Evolution haul network that exists between the destination waypoint (entrance to the dump) and the dumping solid. On-dump paths only apply to block or solid waste dumps, and paths to other destinations will not include this path component.
-
A rule that determines which material is sent to a specific process or mill.
-
A user-defined subdivision of a solid or block, representing a portion of material (for example, ore or waste) whose exact spatial location within the geometry is not explicitly defined. Parcels can be routed and processed independently during extraction.
-
One or more segments connecting two locations (i.e. a source block or solid and a waypoint) in a road network.
-
A point in a pathway that only accepts material transported by certain kinds of trucks.
-
A path in a road network with associated truck information.
-
The container for all data in Evolution (including models, setups, schedules, scripts, and reports), stored as a structured set of files and folders on the file system.
-
The process of combining smaller blocks in a block model into larger blocks to speed up the scheduling process.
-
The process of sending material from a stockpile to a processing destination such as a mill.
-
The cost associated with restoring mined areas or waste dumps to an acceptable environmental condition. This may include costs related to waste dump height or regulatory requirements.
-
A model representing haul roads used to calculate travel paths and haulage times between sources and destinations.
-
The force resisting the motion of a truck’s wheels as it travels along a haul road.
-
The sequence and timing of mining, processing, and material movement activities generated by the optimisation engine.
-
The process of using an existing schedule as a seed so that Evolution retains its results for selected early periods while generating new results for later periods.
-
A single, continuous, non‑curving portion of haul road between two defined points in the network, where the road’s characteristics remain consistent.
-
A configuration in Evolution that defines the models, equipment, constraints, and objectives used for scheduling optimisation.
-
A process that checks a setup for errors, missing components, or conflicting settings before running optimisation.
-
A cone‑shaped, single‑solid stockpile that functions like a regular solid stockpile but uses default cone geometry instead of requiring pre‑existing geometry files. Simple stockpiles make it easier to create and update stockpile models without external CAD or triangulation data and can be added to setups that accept solid models.
-
A setup that has only one primary element selected, producing schedules with optimal cut‑off grades for that element.
-
A non-mandatory constraint that Evolution takes into account when generating a schedule, but which may be violated if doing so produces a better or more feasible schedule.
-
A closed volume with associated attributes (such as grade), representing a discrete unit of material. Solids are the basic unit in Origin Solids and are combined to form solid models.
-
Operations in Epoch that split a dynamic solids model into smaller solids. Solid cuts allow mining shapes to be adjusted so the area of mining can match the planned work for each period. Evolution supports different cutting methods such as direct cuts, target‑seeking cuts (based on quantity targets), and simple cuts (based on direction and target mass). Solid cuts require a dynamic solids model because they need underlying block model attributes.
-
A model composed of multiple solids of varying size and shape, used to represent pits, stockpiles, and waste dumps.
-
A point on the road network defined by the user as the exit point from the pit or stockpile.
-
A set of blocks or solids corresponding to a single mining phase or strip in a model.
-
A temporary destination used to store material for later processing, blending, or reclaim.
-
The ratio describing the increase in volume of material after excavation due to loosening and the introduction of air.
-
A set of model attributes that uniquely define solids for assignment to specific tasks during schedule generation.
-
An ordered sequence of tasks, defined by task keys, that specifies the mining sequence used by Evolution when generating a schedule.
-
The lowest block on a bench or slope that represents the forward boundary of excavation in a block model. Evolution uses the toe block to identify the progressive mining front for sequencing and schedule generation.
-
A modelling process that prepares block or solid models for use in Evolution by defining input data, applying transform operations (such as column filtering, row filtering, reblocking, or maths scripts), and producing an output model in a usable format. Transforms are created when importing or modifying models.
-
A surface composed of connected triangles that defines the geometry of solids within a solid model.
-
The proportion of time that a piece of equipment is actively used.
-
A process component with no geometry attached to it. Virtual objects include mills, screening stations, waste dumps, and virtual stockpiles.
-
A non‑geometric material entity defined by attributes for inclusion in scheduling tasks without requiring a physical solid model.
-
A specially flagged point on a road network. There are five types of waypoints in Evolution: source waypoint, destination waypoint, permission waypoint, force waypoint, and in-pit crusher waypoint. The path between source and destination waypoints is split into three sections: in-pit, ex-pit, and on-dump.
