Construction, Forestry, Mining and Energy Union v State of Queensland

The case of Construction, Forestry, Mining and Energy Union versus the State of Queensland involved a dispute over the adequacy of escapeways at the respondent’s Grasstree Underground mine. The union contested the adequacy of the mine's design, specifically focusing on the two trafficable entrances, which included an input shaft and an exhaust shaft that served as escapeways. The central issue was whether a fire in the input shaft was reasonably foreseeable and whether the protective equipment used in such an event would affect the ability of persons to escape through the other escapeway. The court was required to determine whether the two escapeways were adequately separated to prevent a foreseeable incident in one from impacting the other.

The court examined the statutory requirements under section 296(1) of the Coal Mining Safety and Health Regulation 2001. It assessed whether the mine design complied with the regulation by ensuring that the escapeways were separated in a manner that safeguarded against a reasonably foreseeable event, such as a fire in one shaft, impacting the ability of persons to escape through the other shaft. The court considered the practical implications of the mine's design and whether it provided sufficient safety measures for miners in the event of an emergency.

In its reasoning, the court found that the two entrances from the surface of the mine were not adequately separated to prevent a reasonably foreseeable event in one from affecting the ability of persons to escape through the other. The court concluded that the design did not meet the requirements of the regulation, as a fire in the input shaft could potentially compromise the safety of the exhaust shaft, thereby failing to protect miners effectively. Consequently, the court declared that the two entrances were not escapeways within the meaning of the regulation, as they did not sufficiently prevent the impact of a foreseeable event in one on the other.

The final order declared that the two entrances from the surface of the respondent’s Grasstree Underground mine did not qualify as escapeways under section 296(1) of the Coal Mining Safety and Health Regulation 2001. This declaration arose from the court’s finding that the entrances were not separated in a way that prevented a reasonably foreseeable event in one from affecting the ability of persons to escape through the other.
