Which statement best describes a requirement of the primary escapeway?

• A. An intake airway or adjacent intake airways designated as the primary escapeway, separated as far as practicable from all other roadways by a separation stopping that is certified antistatic, fire resistant and of substantial construction providing for minimal leakage; as far as practicable, free from the risk of fire; firefighting equipment is located on or near any equipment installed in the primary escapeway; and must be trafficable by mechanised equipment unless single or 2 heading developments.
• B. A general passageway with no specific separation, accessible by foot only.
• C. A separate surface corridor used for evacuation only, with no equipment.
• D. A ducted tunnel with no water or fire resistance requirement.

Answer: (A)

The main idea is that the primary escapeway must be a well-protected, clearly defined evacuation path with specific safety and access features. The statement describes an intake airway or adjacent intake airways designated as the primary escapeway that is separated from other roadways by a separation stopping. That stopping must be certified antistatic, fire resistant, and of substantial construction to provide minimal leakage, helping to keep heat, smoke, and gases out of the escape route and reducing fire spread risk. It also requires aiming to be free from fire risk as far as practicable, and positions firefighting equipment on or near any equipment installed in the escapeway to support rescue operations. Importantly, it notes the route should be trafficable by mechanised equipment unless the development is single or two-heading, which ensures responders can reach and assist miners if needed.

The other descriptions don’t meet the full safety and accessibility standard: one describes a general foot passage without required separation or fire-resistant barriers; another imagines a surface corridor for evacuation only with no equipment provision; and another outlines a ducted tunnel with no water or fire resistance requirements. None of those provide the same level of isolation, protection, and practical access required for a primary escapeway.
