What is a key characteristic of a proper shelter hole?

A key characteristic of a proper shelter hole is that it must be clear and adequately sized. This ensures that in the event of an emergency, the shelter can effectively protect individuals from falling objects, debris, or other hazards that could arise during mining operations. Adequate sizing is crucial for allowing easy entry and exit, as well as ensuring that all individuals have enough space to take refuge without being cramped or obstructed.

Having the shelter hole clear of obstructions is equally important as it allows for quick access during emergencies, thereby enhancing safety for all personnel involved. The focus on these attributes aligns with mine safety regulations, emphasizing that shelters are not only functional but also critically important for the well-being of the workers in hazardous situations.
