It's 5:40 a.m. on the section and your bolter operator is standing under freshly cut, unsupported top, waiting on a machine that "felt fine" yesterday. Then the ATRS canopy weeps hydraulic oil, the drill steel wanders, and the first resin bolt of the shift spins without anchoring. A disciplined roof bolter inspection is what stands between that crew and a bad day: a structured pre-shift check of the temporary roof support, boom and drill head, hydraulics, dust collection, water, tramming and brakes, completed before the first hole is drilled. This page walks through what a defensible underground bolter checklist actually covers, why bolter condition is a ground-control issue rather than just a maintenance issue, and how to capture it digitally so the record survives the audit. If you want to see how this runs on real machines, you can book a 30-minute walkthrough on your own bolters and watch a pre-shift inspection happen live.
Ground support equipment - underground bolting
The roof over your crew is only as good as the machine that bolted it
Every person working behind the bolter trusts the support it installed. That trust starts with a machine that was actually checked - canopy, boom, hydraulics, dust control and brakes - before the shift, not pencilled in after.
- ATRS canopy and temporary roof support verified before anyone goes under unsupported top
- Boom, drill head and steel condition checked so every hole meets the ground control plan
- Dust collection and water systems confirmed working for respirable dust control while drilling
- Tramming, brakes and hydraulics signed off with photo evidence, offline, before the first bolt
Why bolter condition is a ground-control decision
What a skipped roof bolter inspection really costs
These are the numbers your safety manager and your accountant both care about. Every one of them traces back to a machine that went to work unchecked.
1 shift
Of lost bolting can idle an entire section - the miner, the shuttle cars and every worker behind the face wait on ground support.
100%
Of your crew under unsupported top relies on the ATRS canopy. There is no partial credit on that protective structure.
4-6 hrs
Typical downtime to swap a failed hydraulic hose or drill motor mid-shift underground, versus minutes to catch the leak on a pre-shift check.
1 bolt
Installed in a wandering, off-pattern hole from a worn drill head can fail a pull test and force a re-bolt of the whole row.
Underground bolter checklist
The six systems every pre-shift roof bolter inspection must cover
A bolter is not one machine - it is six systems that each protect someone. Miss one and you have not done an inspection, you have done a walk-around.
ATRS canopy & temporary roof support
The canopy is the only thing between your operator and unsupported top. Check for cracks, bent members, pin wear, hydraulic drift and full range of motion. Any structural doubt means the machine does not tram to the face.
- No cracks, deformation or weld repairs on canopy or frame
- Canopy lifts, sets and holds without drifting down
- Pins, bushings and linkages within wear limits
Boom & drill head
Hole quality decides bolt performance. A worn chuck, bent guide or sloppy boom pivot drills a wandering hole, and a bolt in a bad hole will not anchor to design. Check feed, rotation, guides and boom pins before drilling.
- Drill steel straight, chuck and centraliser within spec
- Boom pivots and extensions tight, no excessive play
- Feed and rotation smooth through full stroke
Hydraulic system
The canopy, boom, drill and stabilisers all run on the same hydraulic power. Look for weeping hoses, chafed lines near pinch points, low oil, hot spots and slow functions. A small leak underground becomes a fire risk and a lost shift fast.
- No active leaks at hoses, fittings, cylinders or valve bank
- Fluid level and condition within limits, no burnt smell
- All functions respond at normal speed and pressure
Dust collection & water
Dry drilling without a working collector pumps respirable dust straight into the section. Confirm the dust collector, filters and suction, and verify water flow and pressure for dust suppression and bit cooling before the first hole.
- Dust collector draws correctly, filters not blinded or torn
- Water flow and pressure adequate at the drill steel
- Hoses and seals intact, no visible dust escape at the head
Tramming & brakes
A bolter trams in the dark, on grades, around people and other equipment. Test service brakes, park brake, steering, lights and audible alarms. Brake fade on a grade with a worker nearby is not a maintenance ticket - it is a near miss.
- Service and park brakes hold on grade
- Steering, lights, strobes and reverse alarm all work
- No abnormal noise, pull or fade when tramming
Ground control plan fit
Your ground control plan assumes the bolter can reach, drill and install the designed bolt pattern. If the machine cannot achieve bolt length, torque or spacing, the plan on paper is not the plan in the roof. Confirm capability matches the design.
- Bolter can reach full pattern height and width for the section
- Torque and installation meet the bolt and resin specification
- Any limitation is escalated, not worked around silently
Ground support compliance
From inspection point to audit-ready record
When an inspector, a client or an insurer asks how you know the bolter was fit for work, "the operator checks it" is not an answer. This is the record you need to produce, in seconds.
| Inspection point | What you check | Record you must be able to show |
|---|---|---|
| ATRS canopy | Structure, pins, hydraulic hold | Timestamped pass with photo of the canopy, signed before the shift |
| Boom & drill head | Steel, chuck, guides, boom play | Condition note plus photo of any wear flagged for repair |
| Hydraulics | Leaks, level, function speed | Defect logged and auto-converted to a work order if found |
| Dust & water | Collector suction, water flow | Confirmation of dust control before drilling, tied to the operator |
| Tramming & brakes | Brakes, steering, lights, alarms | Brake test result recorded with date, time and machine ID |
| Ground control fit | Pattern reach, torque, bolt spec | Note of any capability limit escalated to the supervisor |
If pulling any of these records takes more than a few seconds, your system is paper, memory or good luck. You can see how this record is produced on a live demo with one of your own machines as the example.
Stop defending bolter inspections from memory
Put a timestamped, photo-backed roof bolter inspection in every operator's hand - and a dispatch block on any machine with a critical defect.
Bolter pre-shift inspection workflow
How a digital roof bolter inspection runs on the section
No paper tag, no radio call, no "I'll tell the shop later." Four steps, done at the machine, even with no signal underground.
Scan the machine, load the right template
The operator scans a QR code on the bolter and the correct underground template loads on any phone or tablet - canopy, boom, hydraulics, dust, water, tramming and brakes, specific to that machine and your ground control plan.
Inspect with forced photo evidence
Protective structures like the ATRS canopy require a photo, not just a tick. The app works fully offline at the face and syncs automatically when the machine or operator surfaces, so no inspection is ever lost to a dead zone.
Critical defects block dispatch
A failed canopy, brake or hydraulic item flags the machine as not fit for work and notifies the supervisor and shop at once. The bolter does not tram to the face on a hope and a handshake.
Defect becomes a work order
One tap converts the defect into a work order with the photo, the machine ID and the operator's note attached. The shop orders the hose or drill part before the machine even reaches the surface.
This is the exact flow you can start running free on your first bolter today, without waiting on a rollout project.
How HVI helps
Built for ground support equipment, not just highway trucks
HVI is cloud + mobile inspection and maintenance work order software for fleet-heavy operations. These four capabilities map directly to the bolter problems above.
QR-loaded underground templates
Each bolter carries a QR code that pulls up its exact inspection template. No wrong form, no generic checklist - the operator checks what that machine and your ground control plan demand.
Forced photo evidence
Protective structures require a photo to close the item. You get visual proof of canopy and boom condition on every shift, which ends the "he checked it" argument in an audit.
Offline capture, sync on surfacing
Inspections run with zero signal at the face and sync automatically when the device reconnects. Your records are complete even on the deepest section, with no manual re-entry.
Dispatch block on critical defects
A critical canopy, brake or hydraulic fault locks the machine out of service until a signed repair clears it. That one rule removes the pressure to "just run it for the shift."
Want to watch a defect become a work order in real time? Book a demo and we will run it on one of your bolters, start to finish.
Key takeaways
Roof bolter inspection is ground control, not paperwork
If you remember nothing else, remember these four points when you defend this to your manager or your crew.
The bolter sets the roof everyone trusts
Every worker behind the face depends on the support your bolter installed. A machine in poor condition installs poor support, which makes its inspection a ground-control task first and a maintenance task second.
Six systems, every shift, no exceptions
ATRS canopy, boom and drill head, hydraulics, dust and water, tramming and brakes, and fit to the ground control plan. A partial check is a missed check, because each system protects a different person.
The record is the defence
When something goes wrong, the question is never "did you mean to check it" - it is "show me the record." Timestamped, photo-backed inspections are the only answer that holds up.
Digital makes it enforceable
Paper can be pencil-whipped and radio calls can be forgotten. A digital roof bolter inspection with forced photos, offline capture and a dispatch block makes the standard real on every shift.
You can sign up free and load your first bolter template in minutes, or book a demo to see the full workflow before you commit.
"I used to find out a bolter had a bad canopy when the night shift supervisor rang me at home. Now the machine can't be dispatched with a critical defect, and I see the photo before my first coffee. The number I watch is bolters that start a shift with an open critical fault - since we forced the photo and the block, that number is zero, and my phone stays quiet."
