According to the Act, when is a mine considered "dangerous"?

The correct understanding of when a mine is considered "dangerous" under the Act hinges on the failure to implement or maintain the controls specified in the Quarry Health Management Plan (PHMP). The PHMP is a crucial document that outlines safety measures, risk management strategies, and the protocols that must be followed to safeguard the health and safety of all individuals working in or around the mining area. If the required controls are not in place or adequately maintained, it creates a significant risk of accidents and hazardous situations, thereby categorizing the mine as "dangerous."

This understanding aligns with a proactive approach to mining safety, where the emphasis is placed on preventive measures and risk management. It highlights the importance of adherence to safety regulations, as even the absence of accidents does not reduce the mine's hazardous status if the necessary safety controls are lacking.

In contrast, a minor accident or equipment failure does not automatically entail that a mine is classified as dangerous, although these events are serious and warrant attention. Similarly, having no employees present does not inherently signify danger, as the risk factors associated with mining operations primarily revolve around the management of hazards rather than mere absence of personnel.
