Mining Annotation Scale Checker
A free, browser-based tool. Runs entirely in your browser — no sign up, nothing stored.
Checklist
Check label text sizes, line weights and print scale on a mine plan before issue — a teaching QA prompt list, not the controlling drawing standard.
Still outstanding
- Plot scale stated and matches the scale bar
- Sheet size and orientation correct
- Scale bar and north point present
- Text heights legible at plot scale (e.g. ≥1.8–2.5 mm)
- Consistent text styles / fonts across the sheet
- Labels not overlapping linework or each other
- Levels / RLs and dimensions readable
- Line weights differentiate features at scale
- Layer / lineweight standard followed
- Hatching and symbols print clearly
- Title block complete (datum, scale, issue, author)
- Revision and issue status correct

How to use this calculator
- Work through the scale & sheet, text & annotation, line weights & layers, and title-block sections.
- Tick each item that passes; the tool shows completeness and what's still to fix.
- Use it as a pre-issue QA pass on a mine plan.
How it works
Whether a mine plan reads clearly depends on how text and linework print at the plot scale. This checklist prompts the usual checks — text height legible at scale, consistent styles, line weights that separate features, and a complete title block.
It's a teaching QA aid, not the controlling drawing standard. Always check against your site's mine-plan and CAD standards.
Worked example
1:1000 mine surface plan. Text plots at 2.0 mm (legible), line weights separate contours from features, hatching prints cleanly, and the title block carries datum, scale, issue and author.
Frequently asked questions
How is this different from the plan annotation scale calculator?
That tool computes the ground size a given plotted text height represents. This is a QA checklist of the things to verify across a whole mine sheet before issuing it.
Is this official course material?
No. It is free study support mapped to surveying course levels — not official North Metropolitan TAFE content or advice. Always follow your lecturer and the official assessment brief, and check your own working.
