| Key Fact 1 | Mining accounts for a disproportionate share of Australia’s occupational disease burden — silicosis, CWP, DPM-related lung cancer, noise-induced hearing loss and heat illness are all significantly concentrated in the mining sector. |
| Key Fact 2 | Unlike most industries which are governed purely by the model WHS Act, the mining sector has additional state-specific legislation with requirements that often exceed the model WHS provisions. |
| Key Fact 3 | A Principal Hazard Management Plan (PHMP) for dust, chemical or noise hazards in a Queensland or NSW mine must go beyond generic risk assessment — it requires specific monitoring, health surveillance, engineering controls and emergency response provisions for each identified principal hazard. |

Occupational Hygiene in Mining: A Comprehensive Compliance Guide for Australian Mine Operators
Australia’s mining sector — encompassing coal mines, metalliferous mines, oil and gas operations, quarries and mineral processing plants — is subject to one of the most complex and demanding occupational health regulatory frameworks in the world. Mine operators must navigate state-specific mining legislation that often imposes requirements well beyond the model WHS Act, while managing a hazard profile that includes some of Australia’s most serious occupational diseases: silicosis, coal workers’ pneumoconiosis, diesel particulate matter-related lung cancer, noise-induced hearing loss, heat stroke and naturally occurring radioactive material (NORM) exposures.
The Mining Hazard Profile
Dust Hazards
Mining involves generating massive quantities of airborne dust through drilling, blasting, crushing, screening, and hauling operations. Crystalline silica from host rock is present in virtually every mining operation — quartz in metalliferous mines, quartz from roof strata in coal mines. RCS WES of 0.05 mg/m³ represents the most critical compliance parameter for underground operations. Coal mine dust (RCMD limit 1.5 mg/m³) and the silica component within it must be assessed separately. Diesel particulate matter from underground and surface diesel equipment requires monitoring and control as a Group 1 carcinogen.
Noise
Mining equipment — drilling rigs, blasting, crushers, conveyors, haul trucks, scrapers — generates some of the loudest occupational noise encountered in any industry. Hearing loss is the most prevalent chronic occupational disease outcome in Australian mining. A comprehensive hearing conservation programme meeting AS/NZS 1269 requirements is mandatory at any operation where workers regularly exceed 85 dB(A) LAeq,8h — which applies to the overwhelming majority of underground and surface mining operations.
Heat Stress
Underground heat from geothermal gradient (temperature increases ~3°C per 100m depth), diesel equipment heat, and metabolic work rate create significant heat stress risk in deep underground mines. Surface mines in northern and central Australia expose workers to extreme ambient temperatures during summer months. Heat illness prevention requires WBGT-based assessment, acclimatisation programmes, and engineered cooling in deep underground operations.
Naturally Occurring Radioactive Material (NORM)
Some mining operations — particularly those processing phosphate rock, rare earth minerals, uranium ore, or mineral sands — concentrate naturally occurring radionuclides (uranium, thorium, radium) to levels requiring radiation protection management. NORM is regulated under state radiation legislation and ARPANSA standards.
Mining-Specific Legislation
Queensland
The Coal Mining Safety and Health Act 1999 and Mineral Resources (Safety) Act govern coal and metalliferous mines respectively. Both require: a Safety and Health Management System (SHMS) for coal mines or Mine Safety and Health Management System (MSHMS) for metal mines; Principal Hazard Management Plans (PHMPs) for each identified principal hazard (including dust, noise, gas); and a Site Senior Executive (SSE) with statutory responsibility for mine safety. Hygiene-specific requirements include mandatory dust monitoring frequencies, B-reader chest X-rays for coal workers, and detailed heat management requirements.
New South Wales
The Work Health and Safety (Mines and Petroleum Sites) Act 2013 creates a regime broadly aligned with the model WHS Act but with additional mine-specific provisions. NSW Resources Regulator inspection campaigns have focused on silica dust controls in both coal and metalliferous operations. The Mine Safety Advisory Council provides guidance on specific hazard management approaches.
Western Australia
The Mines Safety and Inspection Act 1994 and associated regulations (MSIA Regulations 1995) govern all mines in WA. The Department of Mines, Industry Regulation and Safety (DMIRS) regulates occupational health requirements including dust monitoring, hearing conservation and heat management. WA has historically had some of the highest standards for mining health management in Australia.
Principal Hazard Management Plans (PHMPs)
In Queensland and NSW, mine operators must develop PHMPs for each identified principal hazard. For dust, a PHMP must include:
- Identification of all dust hazard sources and types at the mine
- Risk assessment for each dust hazard type
- Engineering and administrative controls to manage the hazard
- Monitoring programme specifying frequency, method and responsibility
- Health surveillance obligations and programme
- Emergency response procedures for significant dust exposure incidents
- Record keeping and reporting requirements
- Review triggers and schedule
PHMPs must be developed in consultation with workers and their health and safety representatives, reviewed at least every 3 years or when conditions change significantly, and be available to workers, their representatives and the relevant regulator on request.
Hygiene in FIFO Workforce Management
Fly-in fly-out (FIFO) and drive-in drive-out (DIDO) work arrangements introduce specific challenges for occupational hygiene programme continuity: workers accumulate exposures across multiple employers and sites; health surveillance records may be fragmented across different health providers; and job changes between sites may not trigger health surveillance updates. Best practice for FIFO operations includes: portability of health surveillance records; health status verification at crew changes; and monitoring programmes that account for split-rosters in dose calculation (longer work periods per rotation).
