Longwall Mining Operations SWMS
Underground coal longwall mining — shearer operation, roof-support advance, chock bleeding, methane gas monitoring, coal dust explosion management, shield interaction with strata, face conveyor operations, emergency egress and self-rescuer protocols.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Longwall mining operations involve shearer-loader cutting at the coal face, automated roof-support (chock) advance, armoured face conveyor (AFC) operation, methane and coal-dust management, and underground emergency egress. This SWMS addresses High-Risk Construction Work under WHS Regulation 2025 and triggers state mining safety duties (NSW CMSH Act 2013, Qld CMSHA 1999, WA MSHR), requiring documented controls, principal hazard management plans, and competent-person supervision before any face operation commences.
Hazards identified
16 hazards covered, sorted by priority.
Explosion causing multiple fatalities and mine-wide destruction.
Secondary explosions through gate roads killing crews kilometres from ignition.
Crushing fatalities of shearer operators and chock attendants.
Fatal traumatic injury from contact with rotating cutting drum.
Severe crush injuries or amputation from chain conveyor inrush.
Fatal crushing during chock advance or bleeding sequence.
Drowning, asphyxiation, or explosion from uncontrolled fluid/gas release.
Underground fire generating CO and triggering evacuation or fatalities.
Asphyxiation of workers in goaf-influenced or stalled airflow zones.
Long-term lung cancer and cardiovascular disease in underground crews.
Coal workers' pneumoconiosis and progressive massive fibrosis.
Silicosis from cutting stone bands within the seam.
Permanent noise-induced hearing loss exceeding 85 dB(A) LAeq8h.
HAVS and lumbar injury from prolonged plant operation.
Fatalities during evacuation if CABA/SCSR not donned correctly.
Severe burns or ignition of methane atmosphere.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Continuous tube-bundle and real-time methane monitoring with automatic shearer trip at 1.25% CH4 and full de-energisation at 2%.
- 2Stone dusting program maintaining ≥85% incombustible content; routine sampling per state mining regulator requirements and Principal Hazard Management Plan.
- 3Only Group I Ex-rated equipment certified to AS 1838 / IEC 60079 used in hazardous zones; permit-to-work for any hot work underground.
- 4Automated chock advance with exclusion zones, pressure interlocks, and proximity detection; no personnel between chocks during bleed/advance.
- 5Strata Control TARPs with convergence monitoring, secondary support, and trigger-based withdrawal authorised by ventilation officer.
- 6Mandatory SCSR carried by every worker, change-over stations along travel roads, quarterly donning drills, and refuge chambers stocked per MDG 1032.
- 7Competent-person supervision (Deputy/ERZ Controller), pre-shift gas testing, and statutory inspections recorded in the statutory record book.
Applicable Codes of Practice
Primary statute for NSW underground coal operations including principal hazard and control plans.
Risk-assessment and guarding standard applied to shearer, AFC, BSL, and chock systems.
Certification standard for electrical apparatus used in firedamp atmospheres at the longwall face.
High-Risk Construction Work triggered
All longwall activity occurs underground in coal seams accessed via shafts and drifts.
Shearer, AFC, BSL, shuttle cars and continuous miners operate at the face and gate roads.
Goaf inspections, seals, and drainage areas meet the confined space definition under WHS Reg 2025.
Written SWMS mandatory before work starts; mine record book entries and PHMPs required; non-compliance attracts Category 1 prosecutions and mine-stop notices.
Who this is for
- →Underground coal mine operators and longwall production crews
- →Mine managers, ERZ Controllers, Deputies and ventilation officers
- →OEM service technicians and contractors performing face maintenance
What you receive
- ✓Editable DOCX SWMS tailored to longwall face operations
- ✓State-specific legislation schedule (NSW CMSH, Qld CMSHA, WA MSHR)
- ✓Hazard register covering all 16 identified longwall hazards
- ✓Worker sign-on register with competency and SCSR drill verification
Worked example
A NSW longwall crew commenced a shear at LW304 with CH4 at 0.9%. Tube-bundle monitoring detected a rise to 1.3% as the shearer cut into a fault zone; automatic trip de-energised the face. The Deputy enacted the TARP, withdrew personnel to the intake, increased auxiliary ventilation, and recorded actions in the statutory book. After CH4 cleared below 0.5% and an inspection confirmed strata stability, production resumed under the PHMP — zero injuries, full regulator compliance.
