Glossary

Words Trackapt uses precisely. Where two terms look interchangeable and are not, the difference is spelled out.

The core

Account holder — the person the account belongs to. A single identity, not a clearance level; Admin clearance does not stand in for it. See Who can do what.

Balance — what should be there, netted from documents. The paperwork half of Trackapt. See Cycles.

Capped figure — a range-based figure set to stop at the last date every input has figures. It says where it stops: "Capped at 15 Sept 2026: SURVEY TONNAGE last measured on 15 Sept 2026". See Capping at the last date every input has figures.

Clearance — Level 1 to 6, or Admin. Decides what kind of action you may take. Does not decide what data you can see.

Computed parameter — a parameter worked out from others by a formula rather than read off an item. Interval-based ones are worked out for every time slot; range-based ones once over the period you pick. See Computed parameters.

Cycle — a process whose stages are separate documents, joined so the figure at the end means something. See Cycles.

Department — a lens that groups tracker groups and form templates by team. Not an access control. See Departments.

Item (also tracker) — one of the things you track. See Tracked items.

Item property — something an item is described by, beyond its name. Declared on the group, valued per item. Removing one destroys its values permanently.

Monitored parameter — something read off an item and recorded. The looking-at-the-thing half of Trackapt. See Parameters and units.

Plan — the figure a reading is judged against: the dial, the variance and the green-or-red standing are measured from it. A parameter whose goal is Reading has none. See The plan.

Plan by period — a different plan for each period, at any cadence from daily to annual, in front of the single figure. A reading is held to its own period's figure. See Plan by period.

Reading — one recorded value of a monitored parameter.

Tracker group — a category of items that belong together and are described the same way. See Tracker groups.

Whitelist — the list of tracker groups a member may see. The real access control, and it cascades to every screen including the modules.

Forms

Approval order — named stages that must be signed in sequence. An alternative to a flat approval count; you set one or the other.

Carry forward — a field that starts a new entry off at the value of a field on a previous entry of the same form. Copied once, and editable. See Carry-forward fields.

Computed field — a field worked out from other fields on the same entry. See Computed columns.

Dynamic form — one continuously-updated live document whose records are frozen snapshots, rather than a stream of entries. See What a form is.

Entry — one filled-in copy of a form.

Entry number — a per-form document number such as INV-000001. The counter only counts up, so a deleted entry leaves a gap. See Entry numbering.

Field key — the identity a stored value uses to find its field again. It is why a removed field is archived verbatim rather than rebuilt.

Form field only — a field on a group-linked section that does not publish a reading, as opposed to form field + tracked parameter, which does.

Mirror field — a read-only field on a dynamic form showing a monitored parameter's latest reading. The opposite of carry forward: live, never editable, never writes back.

Pending edit — a correction saved against a submitted entry but not yet published. Blocks approval. See Correcting a submission.

Raising — drawing a form's rows and figures from a document filed on another form. See Raising a form from an entry.

Reference field — a field whose options come from the system — a group's items, or another form's entries — rather than from a list somebody typed.

Retired field — a removed field, archived with its identity intact so it can come back as itself.

Snapshot — a frozen record of what a dynamic form said at a moment. Immutable; deletable but not editable.

Outbox — work saved on the device because there was no signal, waiting to be sent. See Working offline.

Provenance — the record of which spreadsheet an entry's figures were read from: a file name, a size and a checksum. The workbook itself is not kept.

Template — the blank form.

Modules

Availability — uptime as a share of a window. (Maintenance)

Commitment — money promised by an issued order but not yet spent. (Procurement)

Block model — the deposit divided into blocks, with a grade estimated onto each. What is read off it is the grade-tonnage curve. (Mining)

Boundary — an outline kept against an item, inside which a volume is measured. Two can be combined into a third; the originals stay on file. (Mining)

Breakline — a feature line a surface must respect rather than smooth over: a crest, a toe, a road edge. (Mining)

Exchange API — the token-authenticated interface a program uses to pull a plan's reserve, schedule and demands, a block model, a survey or a design, and to push a schedule back. Version 1 lives under /api/exchange/v1. (Mining)

External reference — the name a block model, wireframe or design goes by in another package — Reference elsewhere on its editor. It rides along in every file the record leaves in. (Mining)

Feed quality — an attribute of the block model, beyond the grade, that the plant is sensitive to: sulphur, silica, moisture. Carried into the reserve as a tonnes-weighted mean and, where a band is set, held or reported. (Mining)

Imported plan — a plan whose schedule was decided in another package. Its takes are exactly what the file said; Compute reports what they cost and changes no fraction. (Mining)

Integration token — a secret a program presents to the exchange API, made under Integrations, shown once, and revocable. It acts as the account holder for reading. (Mining)

ELOS — equivalent linear overbreak: how far a stope wall sloughs in, in metres of wall. How unplanned dilution is carried, because it does not depend on the stope's own width. (Mining)

Equipment group — a tracker group ticked as Equipment when it was created. The only kind of group a vehicle, an asset or a mine plan's fleet unit may be filed under. (Maintenance, Fleet, Mining)

Blast — a block of a bench, the holes drilled into it and what each is loaded with, from the first draft to the muckpile. Its holes are stored, so the field can move, add and remove them until it is fired. (Mining)

Box cut — a blast with no open side within two burdens to throw towards, fired as a V from the centre so it makes its own face. Its rows run along the edge with the lowest ground beyond it. (Mining)

Burden — the distance from one row of holes to the next, and from the first row to the free face. The figure the rest of a pattern follows from. (Mining)

Charge sheet — what the charging crew loads, hole by hole: depth, stemming, column, kilograms, product and firing time, with the totals. (Mining)

Drill yield — tonnes broken for every metre drilled. What a plan's drill process is charged at when it designs from the pattern. (Mining)

Filler hole — a hole the blaster adds to the drafted pattern where the face is ragged or a hole was lost. Charged like any other, and marked Added by hand. (Mining)

Free face — the open side of a block the rock is thrown towards. Rows run parallel to it. (Mining)

Powder factor — explosive per unit of rock broken, kg/m³ or kg/t. Worked on the rock between the ground and the floor, so a filler hole raises it. (Mining)

Rock factor — how hard a rock is to break, for the fragment-size prediction: about 6 for weak rock, 12 for hard. A reconciled blast suggests the one your ground behaves as. (Mining)

Stemming / sub-drill — the crushed rock left at the top of a hole to keep the gas in; the length drilled below the floor to break the toe. (Mining)

Front row — the holes next to the free face. Their burden is read off the surveyed ground rather than assumed, because a real face leans and keeps toes. (Mining)

Tie-up — how a shot is connected on the bench: where it is started, the surface connector between each pair of collars, and the downline in each hole. A hole's firing time is the shortest path the signal takes to reach its collar plus its own downline. (Mining)

Surface connector / downline — the delay clipped between two collars on top of the ground; the delay that goes down the hole with the primer and holds that hole back behind the signal that passed its collar. (Mining)

Scatter — how loosely a delay holds its nominal figure, as one standard deviation and as a share of that figure, because a long delay scatters wider than a short one. What turns a nominal 8 ms window into a worse one. (Mining)

Cut-off — a surface connector the ground moves before its signal has passed. The line is cut there, and every hole behind it stays charged and unfired. (Mining)

Effective burden and spacing — the burden and spacing the timing makes of a drilled pattern, measured along the way the firing times fall away and across it. An echelon tie can work a 3.0 × 3.5 m pattern as 2.4 × 4.4 m. (Mining)

Swell — how much more room broken rock takes up than it did in place. Fitted to a mine's own ground once it surveys its muckpiles. (Mining)

Toe burden — the rock in front of a front hole at its toe, just above the grade. Much more than the burden is a hard toe that will not dig; a hole is leaned towards the face, or brought forward, to fix it. (Mining)

Grade surface — a designed floor the holes are drilled to where the floor is not one level — a ramp or a drainage fall. Each hole reads it under its own toe. (Mining)

Lean — a hole's angle from vertical, towards the face. A hole's length is worked along it. (Mining)

Rock domain — a kind of ground in an underground mine, with the figures its designs are worked out from, each marked where it came from: measured, block model, typical, calibrated or stated. (Mining)

Rock constant — c, the kilograms of explosive per cubic metre it takes just to break a rock free. About 0.4 kg/m³ in most hard rock; calibrated from the mine's own rounds. (Mining)

Development round — the holes drilled and fired into a heading's face in one shift, designed once and fired shift after shift as the face advances. (Mining)

Burn cut — the centre of a round: loaded holes round one or more large empty relief holes, fired first so the rest of the round has an opening to break into. (Mining)

Pull — how far the face advances in one firing. (Mining)

Look-out — the small angle a round's perimeter holes are drilled outwards, so the next round has room to collar. (Mining)

Smooth blasting — perimeter holes drilled closer together and lightly charged, so the wall or back is left sound with little overbreak. (Mining)

Stand-off (ore) — the waste each hole of a blast leaves above the top of the ore beneath it, so no ore is blasted with the waste. (Mining)

Cut and fill — material removed and material placed between two surveys. Always reported separately, never netted. (Mining)

Design storm — the one storm a pit's sump and pumps are tested against: a depth over so many hours, with the return period it was read for as a label. (Mining)

Desurvey — working out where a drillhole interval actually is in space from the hole's downhole survey. Depth along the hole is not elevation. (Mining)

Dewatering — what a plan says about the water in a pit: what catches the rain, what comes in from the ground, the sump, and the pumps. One block per pit. (Mining)

Diversion drain — the cut-off drain run round a pit beyond its top crest, so ground beyond it sheds away. Only the strip between the crest and the drain still drains in. Set on the pit design, in metres out from the crest. (Mining)

Heading — an underground excavation driven along a centreline: a decline, a drive, a crosscut or an ore drive. Priced and scheduled by the metres driven. (Mining)

Full-to-full — the only pairing of fills that can produce a consumption figure, because it is the only one where the starting level is known. (Fleet)

Gross / tare / net / payable — the heavier weighing, the lighter weighing, the difference, and the difference after deductions. Deductions never change the net. (Weighbridge)

MTBF / MTTR — mean time between failures, and mean time to repair. Open stoppages are excluded from MTTR. (Maintenance)

Never counted — an item whose stock figure has never been anchored by a physical count. (Retail)

Not costed — an item no delivery has ever been booked in for, so its cost is unknown and it values at zero. (Retail)

Origin — where a job came from: schedule, fault, inspection or request. (Maintenance)

Pickup — one set of shots as they came off the instrument. A surface is one reading of a pickup, not the same thing as it. (Mining)

Punch / shift / pattern — one clock event; one in paired with one out; the rules for turning the first into the second. (Attendance)

Recovery curve — recovery stated against grade rather than as one figure, so every block yields product at the recovery its own grade reads off the curve. (Mining)

Reserve — what a plan read off the ground and the model before scheduling it: one unit per bench, or per stage's cut through a bench, per pit, with its tonnes, grade, product and qualities. Pinned with the result, and the table a scheduling package schedules from. (Mining)

Running surface — the ground as it stands, kept up to date by every pickup imported into it. Read as it stood on any date. (Mining)

Runoff coefficient — the fraction of rain on a piece of ground that runs off it rather than soaking in: about 0.9 for bare rock and haul roads, about 0.5 for a loose-rock dump. (Mining)

Scenario — a draft copy of a plan kept beside it so one thing can be changed and the two compared. A plan in every other respect. (Mining)

Sublevel — a level cut between main levels, and the vertical extent of one stope. (Mining)

Stope — the void left where ore has been drilled, blasted and mucked out underground, and the unit an underground plan schedules. Everything mucked from it is fed to the mill: nothing is sorted underground. (Mining)

Seam — an orebody that is a sheet rather than a lump: a chromitite on the Great Dyke, a coal seam, a reef, tens of centimetres thick and hundreds of metres down dip. Modelled in Seams as a grid in plan — floor level, true thickness and grade per cell — rather than as blocks. (Mining)

Accumulation — a seam's grade times its thickness. What a seam's grade is estimated through, so a thin rich intersection and a thick lean one are weighed by the rock in them; a cell's grade is its accumulation over its thickness. (Mining)

True thickness — a seam's thickness measured square to the seam. A hole not square to it reads the seam longer; the seam's dip is what corrects it. (Mining)

Stoping height — the least height a seam panel is broken to, square to the seam: what people and machines work in. Where the seam is thinner, the rest is wall rock fed with it, which is what sets a thin seam's mill grade. (Mining)

Extraction — of the seam in a panel, the share mined; the rest stands as pillars. Square pillars of 6 m at 12 m centres leave a quarter standing, so 0.75. (Mining)

Crown pillar — the rock left standing over a seam near surface, so the workings below it do not break through. Measured from the ground down to the seam's roof. (Mining)

Strip ratio — the waste a strip of an open cut carries for every tonne it feeds, tonnes per tonne. It climbs strip by strip down dip over a seam, and where it passes what the seam can pay for, the open cut ends. (Mining)

Highwall — the wall an open cut leaves standing on its deep side. The final one is stripped with the last strip, and moving the limit a strip deeper moves it deeper. (Mining)

Stage — a pushback or cutback on a pit design that must be taken before or after another part of the same pit. The schedule optimiser's sequencing rule, kept on the design. (Mining)

Sump — the box dug below a pit floor where the water collects and the pumps stand. On the design it is a depth and a plan area; its capacity is what a storm has to fill before the floor floods. (Mining)

Service — recurring work plus the interval it recurs on. (Maintenance)

Stoppage — an interval during which an asset was unavailable. The only thing in Trackapt recorded as an interval rather than a point in time. (Maintenance)

Tipping pad — the top of a waste dump, where the trucks tip. Wide enough for a truck to reverse to the edge, tip and turn, or the dump cannot be worked whatever it holds. Set as a dump design's least top width. (Mining)

Truck cycle — the time a truck takes to load, haul, dump and return, worked from its speed against total resistance — grade plus rolling resistance — over each segment of the road. A haulage capacity from a truck cycle is the tonnes a fleet can carry round it in the period. (Mining)

Three-way match — reconciling order, receipt and invoice. (Procurement)

Tolerance — how much difference is not worth reporting. (Procurement)

Landing — a level a dump's ramp reaches, and so a level the dump can be tipped at while that lift is being built. (Mining)

Void — a lettable unit with no active lease. (Property)

Webhook — an address told, by a signed JSON post, when a plan is published or unpublished. Registered under Integrations; the signature is an HMAC under the hook's own secret. (Mining)

Wireframe — a geological interpretation as a closed solid. Its volume means nothing unless it is closed, so it is re-measured on sight. (Mining)

Pairs that are easy to confuse

These two	Differ in
Hiding and parking a group	Hiding changes no figure. Parking removes the group from every total.
Clearance and the whitelist	Clearance is what you may do; the whitelist is what you may do it to.
Department and access	Departments arrange; access permits.
Balance and monitored parameter	What should be there, versus what somebody found.
Computed field and computed parameter	One works across a form entry; the other across a group over time.
Carry forward and a mirror field	Copied once and editable, versus live and read-only.
Net and payable	The mass weighed, versus the mass paid for.
Retiring a field and removing an item property	The first is archived and restorable. The second is permanent.
Unknown and zero	Trackapt never treats a missing value as a zero.
Recorded on and effective from	When somebody keyed a property change, versus when it took effect.
Offline filing and a spreadsheet import	Both work without signal; one queues the form, the other keys it in Excel.
A pickup and a survey	The measurement, versus one reading of it.
The plan and a plan by period	One figure for every day, versus a figure per period that stands in front of it.
Changed on and takes effect from (a plan)	When somebody changed a plan, versus the day it starts judging readings.
Plan length and slope length	Across the map, versus over the ground. A haul distance is the second; a setting-out offset is the first.
Signing in and checking in	Which login this is, versus which person is at it.
