Roof bolters, mining, use roof bolting machines underground to drill holes, install roof support bolts, and check tightness; before work they verify roof and rib hazards, gas, ventilation, and equipment condition, and on anomalies they stop, withdraw, and escalate.
Roof bolters, mining, first verify underground roof and rib condition, gas, and ventilation, then position the roof bolting machine, drill holes, install bolts, and check tension; for loose rock, roof anomalies, gas, or guarding failure they stop work and escalate per mine procedures.
Continuous mining machine operators handle extraction, underground loading and haulage machine operators handle material transport, drillers handle formation drilling, and mining engineers handle design and safety systems. Roof bolters deliver roof support installed per plan and recorded.
Roof bolters, mining (O*NET 47-5043.00) operate roof bolting machines underground: inspect the roof and ribs, verify gas and ventilation, position the machine, drill bolt holes, install resin or mechanical bolts, and measure tension and record per plan. Coal extraction, loading, or blasting duties must not be automatically assigned to this position.
O*NET 47-5043.00 provides roof bolter tasks and work activities; the BLS 2025—2035 occupational projections table for 47-5043 gives employment and median annual wages, and the O*NET national wage page gives BLS 2025 percentiles. The survey scope, period, and occupational codes of different statistical programs must be labeled separately.
2025 national mining urban non-private sector pre-tax annual average wage (National Bureau of Statistics Table 2). The industry covers many occupations; for scenario reference only, not the wage of roof bolters.

Ignoring unsupported areas or equipment guarding is a caution signal.
Practice anomaly handover with fictional hole position, gas, and tension logs.
O*NET is used to verify occupational tasks and work activities.
The O*NET wage page is used for U.S. occupational percentiles and does not predict individual income.
BLS is used for typical training and employment projections.
O*NET is not a mine safety regulation.
Danger zones and personnel positioning should be verified per the on-site plan.
Warning and communication procedures must be verified per the work scenario.
ILO is used as cross-occupation AI task background and does not provide a roof bolter substitution rate.
NIST is used only for AI governance, not underground mine regulations.
This module focuses on roof and rib collapse, gas and ventilation, roof bolting machine pinch points, drilling dust, tension failure, and handover; specific controls follow mine procedures.
First verify the support plan, roof, gas, ventilation, equipment, unsupported areas, and stop-work authority; when key conditions are unclear they must not be filled in from experience or AI.
The risk scenarios are editorial simulations, not incident rates; O*NET tasks support the occupational scope and cannot replace mine safety regulations.
Roof bolters and nearby underground personnel
Loose roof or rib rock may fall or form a collapse.
Verify roof inspection and unsupported areas, stop work on anomalies, and ask the lead to review.
Simulation: the support drawing does not mark new on-site cracks.
Roof bolters, ventilation personnel, and the extraction crew
Abnormal gas or insufficient ventilation can make the work environment uncontrollable.
Verify monitoring and airflow, and stop work and withdraw per mine procedures on anomalies.
Simulation: the gas detection record is missing, but someone demands that drilling continue.
Roof bolters and maintenance personnel
Roof bolting machine guarding or hydraulic failure can cause crushing or loss of control.
Stop and isolate defective equipment, and have repair and return to service done as authorized.
Simulation: the bit is loose and the guarding is damaged.
Roof bolters, extraction personnel, and the incoming shift
Hole positions or bolt materials that do not match the plan may weaken support.
Compare against the original support drawing, materials, and tension records, and isolate and escalate deviations.
Simulation: the material label does not match the approved plan.
Roof bolters, quality, and the incoming shift
Missing tension inspection lets unverified support be mistaken for acceptable.
Record the instrument, hole positions, measured torque or tension, and unreleased areas.
Simulation: the system shows acceptable, but the test hole was not inspected.
Roof bolters, the lead, and the following extraction crew
Unclear handover of unsupported areas and stop reasons may let later personnel enter by mistake.
Mark unsupported areas, responsible persons, and return-to-work conditions; support plan changes require approval.
Simulation: the handover only says "supported", without marking unfinished holes.
O*NET supports the scope of underground support tasks and does not provide incident rates.
Equipment inspection frequency and methods follow mine and manufacturer procedures.
Gas, ventilation, roof, and unsupported areas follow the mine plan.
O*NET tasks do not grant design change or return-to-work approval authority.
NIST is used only for AI governance, not as a substitute for underground safety rules.
| Able to identify missing monitoring and escalation responsibility |
| Submit fictional stop-work handover sheets |
| Does not equal ventilation position qualifications |
| Quality review trainee | Learn test holes, torque, and tension records | Able to isolate uninspected support | Submit fictional retest cards | Closer to support quality |
| Equipment maintenance collaboration trainee | Learn fault stopping and maintenance handover | Able to distinguish operating and repair authority | Submit simulated equipment isolation tickets | Does not grant repair or return-to-service rights |
Education and fundamentals
The typical BLS 47-5043 entry is a high school diploma or equivalent with moderate-term on-the-job training.
Employers must train according to mineral type and equipment.
Mine and equipment authorization
Underground work, gas and ventilation, machine adjustment, repair, and return-to-work authority are separated.
Verify local and employer procedures.
Task evidence
Support drawings, hole positions, materials, tension, and stop-work records can show the process; relative predictive validity for hiring has not been verified.
Fictional cases show the boundaries.
Tools and records
Able to read equipment instructions, inspection cards, and approved plans and keep versions clear.
Equipment operating permits and roof bolting machine and bolt material competence must be demonstrated separately.
Practice setup｜All fictional, no connection to a real mine
You are a supervised trainee who only checks support drawings, gas, and tension records and does not give real drilling parameters.
A1｜The support drawing marks 0.8 meter hole spacing, while the on-site card says 0.8 centimeter, a unit conflict.
A2｜The gas detection record is missing, but the crew still demands that drilling start.
A3｜The bolt material batch does not match the approved plan.
A4｜The test hole tension was not measured, yet the system shows "acceptable".
A5｜The unsupported area marking is unclear; the trainee can only stop work and report, and return to work is decided by authorized personnel.
Task one: mark items that cannot be released
List A1 unit conflict, A2 gas record, A3 material mismatch, A4 tension evidence, and A5 unsupported area issues.
Do not calculate real hole spacing, gas thresholds, or return-to-work conditions.
Task two: write the review and handover
Make a checklist by problem, roadway location, original support drawing, equipment status, responsible person, and evidence pending.
Request verification of units, gas, materials, and tension records.
Record reported, retested, and approved-for-return-to-work separately.
Safety boundaries
This practice has no complete engineering conditions, equipment parameters, or authorization; AI can organize the problem list but cannot confirm safety or approve support.
Support drawing and unit card
Mark the A1 unit conflict and suspend work at that hole position.
Others can see the unresolved specification problem.
Gas and material card
Place A2 the missing monitoring and A3 the material batch mismatch side by side.
Do not treat a verbal "no problem" as verification.
Tension and unsupported area card
List A4 the lack of inspection, A5 the area marking, and the return to work pending confirmation.
Do not write a stopped work face as approved for return to work.
Plan change list
For the A4 bolt hole position change record, note the proposer, time, approver, and current status.
The person taking over can use this to maintain the stop-work status and wait for approval.
| Stage | What may be assessed | Observed evidence | Use boundaries |
|---|---|---|---|
| Support drawing verification | What to do when hole spacing units conflict | Able to propose stopping and rechecking the original drawing | An interview question does not grant drilling authority |
| Gas verification | Whether work can continue when detection records are missing | Able to require monitoring and escalation | Does not guess safety thresholds |
| Tension verification | What to do when the system shows acceptable but the test hole was not measured | Able to isolate the result and remeasure | Does not guess a passing conclusion |
| Handover review | How to mark unsupported areas | Able to clearly state the location, responsible person, and evidence pending | Practice does not predict long-term performance |
Day one
Read A1, and mark the unit conflict and the reason for stopping.
Day two
Read A2 and A3, and verify gas and materials.
Day three
Read A4 and A5, and write the tension and unsupported area handover.
Day four
Read A4, and record the bolt hole position change and plan version, without inferring that it has been approved.
Day five
Complete the A1—A5 problem list, assigning a responsible person and evidence to each unknown item.
Day six
Ask an experienced person to review only the practice text and check whether assumptions were written as facts.
Day seven
Keep the first draft and the revised draft, and review omissions, stop-work judgments, and communication quality.

This page has no verifiable unified qualification list for Chinese roof bolters, mining; check the target region, industry, and employer requirements.
U.S. vocational education statistics cannot replace Chinese position admission requirements.
Simulated materials contain no real loose rock, equipment, or on-site parameters and must not be used for work.
Education, training, certificates, and equipment authorization are verified separately. Comparable hiring samples, qualification bodies, and specific mine rules for this position in China have not been obtained, so no unified starting pay or entry threshold can be given.
Certificate directories only suggest possible training directions; qualifications, employer appointments, and equipment authorization must all be verified separately.
The four stages represent capability growth, not fixed years or a promotion guarantee; job titles, equipment, and sign-off authority are determined by the employer and local rules.

This page did not obtain a precise occupational wage for roof bolters, mining, in China; National Bureau of Statistics mining averages serve only as industry background.
BLS projects a 18.9% employment decline over 2025—2035, with about 100 annual openings, mainly including replacement; openings do not equal net growth.
There is no reliable AI substitution rate for this occupation. AI can organize support records, while the roof, gas, ventilation, hole positions, and tension are still verified by people.
Stop work and escalate per procedure for loose roof, abnormal gas or ventilation, roof bolting machine failure, mismatched materials, or uninspected tension.
Use only fictional support drawings, gas, and tension logs to practice specification conflicts and stop-work handover; do not connect to a real mine.
You can explore extraction, underground haulage, drilling, or mining engineering; the target equipment, training, and duty evidence must be added.
AI can assist with support drawings and record drafts; the roof, gas, ventilation, hole positions, materials, and tension must be verified by trained on-site personnel.
Occupational tasks follow this page's O*NET and related BLS occupational materials; U.S. wages keep the original precise or clearly parent-category／combined basis, and employment trends use the BLS 2025—2035 projection.
