Vehicle interactions remain one of the highest-risk activities in open-cut mining.
When two hundred tonnes of steel meets poor road design, the results are rarely forgiving.
Recognised Standard 19 (RS19) — Design and Construction of Mine Roads — sets the minimum expectations for how roads in Queensland coal mines must be built and maintained to keep those risks at an acceptable level.
But for most operations, the challenge isn’t understanding what RS19 says. It’s proving that your mine roads actually meet it — and keeping that evidence up to date.
This article explains RS19 in simple, practical terms and highlights how modern digital tools like HazView make compliance easier, faster, and traceable.
1. What is Recognised Standard 19 (RS19)?
RS19 is issued under Part 5 of the Coal Mining Safety and Health Act 1999 and outlines how to achieve an acceptable level of risk for the design and construction of mine roads.
It applies to all mine roads in surface coal mines, including surface areas of underground coal mines.
The intent is simple:
Well-designed roads reduce vehicle interaction hazards and save lives.
The Inspectorate considers RS19 when assessing a site’s traffic management plan or road audits. If your mine follows RS19 — or demonstrates a system that achieves equal or better control — you’re compliant.
2. Why RS19 Matters
Vehicle interaction remains a principal hazard.
Investigations into fatal and serious incidents have repeatedly found road design, drainage, or signage deficiencies as contributing factors.
Common findings include:
- Intersections built at unsafe angles.
- Berms that have settled below specification.
- Roads too narrow for modern haul fleets.
- Poor delineation and lighting in fog or night conditions.
Every mine has good intentions. But without consistent records, it’s impossible to prove compliance.
PowerPoint sketches, email chains, or scattered checklists don’t create a verifiable history — and that’s what inspectors look for.
That’s where systems like HazView come in: an interactive, auditable map that automatically tracks every road, berm, intersection, and checklist entry.
3. Road Types Explained
RS19 defines four basic categories of roads:
| Type | Description | Lifespan |
|---|---|---|
| Primary haulroad | Main haulage roads for moving overburden and coal. | Long-term (life of pit) |
| Secondary haulroad | In-pit or bench roads advancing with mining. | Short-term |
| Primary access road | Main LV/MV routes to key areas. | Long-term |
| Secondary access road | Temporary LV access (pumps, drills, draglines). | Short-term |
Each road type has different design and maintenance expectations.
In practice, that means each should be identified, logged, and inspected separately — something paper or Excel struggles to manage once a site grows.
4. Mine Road Construction Basics
RS19 requires roads to be:
- Well-drained and stable.
- Capable of supporting the expected traffic load.
- Hard-surfaced to minimise skidding and dust.
Layers of Construction
- Sub-grade: The natural ground or compacted base.
- Sub-base: The main load-bearing layer — usually coarse, dry, and compacted in layers.
- Base course: Strong, well-graded material (< 250 mm) without clays or carbonaceous matter.
- Wearing surface: 200 mm thick hard layer, balanced for dust control and friction.
Survey control should be used for primary roads to ensure they match design specifications.
Common pitfalls:
- Road maintenance changing surface levels (losing drainage).
- No record of when material was replaced or re-compacted.
- Separate teams holding isolated data.
HazView’s field checklists and image logging solve this — giving each road section its own verifiable record.
5. Geometric Design Standards
Road Width
- Single lane: 1.5 × vehicle operating width
- Double lane: 3.5 × vehicle operating width
If width can’t be achieved, a risk assessment and control plan (signage, speed limits) is required.
Crossfall / Camber
1–4 % slope to shed water without affecting steering or tyre wear.
Over-watering or poor camber is a leading cause of corrugations and edge failure.
Alignment
- Smooth horizontal and vertical curves with the largest radius possible.
- Avoid compound or reverse curves without straight separation.
- Never place tight curves at ramp crests or bases.
Superelevation
- 2–6 % on curves; avoid negative camber.
- Apply run-out gradually before and after curves.
Grade
- Keep below 10 % where possible.
- Steeper grades require risk assessments and speed controls.
- Flatten grades near intersections to improve sight distance.
Shoulder & Drainage
- Berms or barriers required wherever drop-offs > 0.5 m.
- Drainage must prevent water entering the road structure — one of the most common failure points.
👉 Key takeaway: RS19 isn’t about perfection — it’s about consistency and evidence. Without drawings, photos, and timestamps, “the grader fixed it last week” doesn’t demonstrate compliance.
6. Intersections
Intersections are responsible for a large share of high-potential incidents.
RS19 dedicates an entire section (Clause 13) to their design.
Design Principles
- Intersecting roads must meet at 90° ± 5°.
- Avoid “Y” intersections and multi-leg layouts.
- Minimum 25 m flat zone at the base or top of ramps.
- Provide SISD (Safe Intersection Sight Distance):
- 10 km/h → 10 m
- 40 km/h → 70 m
- 70 km/h → 145 m
Traffic Control
- Stop signs or right-of-way rules for all intersections.
- Median berms ≤ 1.2 m to separate lanes without blocking vision.
- Signage must comply with AS 1742 / 1743.
Intersections also require a documented review and approval process before opening to traffic — something that rarely happens unless it’s baked into a system.
HazView’s intersection layer automates this: every intersection mapped, checked, and archived.
7. Sight Distances and Berms
RS19 links sight distance directly to stopping distance. Drivers must always see far enough ahead to stop safely.
Safety Berms
- Required wherever drop-offs exceed 0.5 m.
- Minimum height:
- Trapezoidal: ≥ 50 % of tyre diameter.
- Triangular: ≥ 66 % of tyre diameter.
- Increase to ≥ 3 m for high-risk edges or poor materials.
- Inspect and maintain regularly — erosion and settlement reduce height quickly.
Centre Dividers
Use median berms (½ tyre height) to separate lanes on downhill left curves or in fog zones.
Traditional berm inspections rely on paper forms or spreadsheets.
In HazView, inspectors log berm height, photo evidence, and comments directly on the map — stored for audit review anytime.
8. Signage, Delineation & Bollards
Signage
- Must comply with AS 1742 and AS 1743.
- Size A (600 mm) for ≤ 150 t trucks; Size B (750 mm) for larger fleets.
- Reflective, visible at night, and placed 1.5 m above surface.
- Warning signs = 1.5 × speed limit before hazard (e.g. 75 m at 50 km/h).
Delineation
- Guideposts ≤ 100 m apart (straight), ≤ 50 m on curves/crests.
- Red reflectors = left, white = right.
Bollards
Install around buildings, sumps, conveyors, and infrastructure to prevent vehicle intrusion.
Even the best signage deteriorates — dirty, missing, or outdated signs are common audit failures.
HazView helps sites maintain signage registers and inspection dates in one central record.
9. Vehicle Separation and Roadside Hazards
Where practicable, RS19 requires separate road networks for heavy and light vehicles.
If that’s not possible, intersections and crossover points must be minimised and clearly signed.
Roadside hazards — trees, drains, poles, rocks — must be either removed or shielded with berms or barriers.
This is one of the most difficult aspects to keep current; conditions change daily.
Digital field logging ensures updated maps reflect actual site conditions — no lag between paper forms and GIS teams.
10. Overhead Structures and Lighting
Overhead hazards remain a recurring cause of serious incidents.
Powerline Clearances
| Voltage (kV) | Minimum Clearance |
|---|---|
| ≤ 1.1 | 1.0 m |
| 1.1–33 | 2.3 m |
| 33–66 | 2.5 m |
| 66–110 | 3.0 m |
| 110–220 | 4.0 m |
Each crossing must be surveyed, recorded, and signposted with maximum permissible vehicle height and crossing number.
Lighting should ensure clear visibility on haul roads and intersections without glare or “black hole” zones.
HazView maps overhead structures alongside height restriction data, preventing mismatched spreadsheets or forgotten updates.
11. Audits and Inspections
RS19 Section 21 requires:
- Annual mine-wide audit for compliance, considering both day and night conditions.
- Daily inspections of active haul roads and intersections by competent persons (OCEs or supervisors).
- Culvert and structure checks for deterioration.
- Height clearance reviews to detect surface build-up.
In practice, many mines meet the physical requirements but fail on record-keeping.
Audits are incomplete, inspections undocumented, or evidence buried in multiple folders.
HazView eliminates this gap. Each inspection is logged with photos, timestamp, user, and checklist reference — automatically generating the evidence trail inspectors expect.
12. How RS19 Ties Into the Broader Safety System
RS19 doesn’t stand alone. It supports your:
- Traffic Management Plan
- Principal Hazard Management Plan for vehicle interactions
- OCE and SSE statutory reporting obligations
If those systems aren’t aligned — or if they depend on manual collation — compliance becomes reactive rather than proactive.
Digital platforms like HazView unify them: one map, one report, one truth.
13. Achieving Practical RS19 Compliance
To comply with RS19, a mine must be able to:
- Design and maintain roads to the required geometric and construction standards.
- Demonstrate those standards through verifiable records.
- Review and audit road networks regularly.
- Manage change — new ramps, evolving fleets, seasonal conditions.
Traditional checklists capture snapshots; they don’t show history.
RS19 compliance relies on proof over time — consistent, timestamped records of inspection, maintenance, and verification.
HazView provides that track record automatically.
14. Bringing It All Together
RS19 isn’t new, but enforcement focus has never been higher.
Inspectors are looking beyond paperwork — they want evidence of visibility, control, and traceability.
If your current system involves:
- Screenshots in PowerPoint,
- Paper checklists in site offices, or
- Road data stored across multiple folders…
…it’s time to modernise.
HazView brings it all into one platform — live hazard maps, intersection layers, inspection checklists, and automatic reporting — giving SSEs and OCEs confidence their roads, berms, and signage meet RS19 every day.
