What type of protection should be provided for persons along haulage-ways?

The correct answer is that shelter holes should be provided for persons along haulage-ways. Shelter holes serve as designated safe areas where individuals can take refuge in the event of an emergency, such as the approach of a vehicle or equipment. This is particularly important in mining operations where haulage-ways can be busy and present numerous hazards, including the risk of being struck by moving equipment.

Having shelter holes ensures that workers have a quick and accessible place to go in order to protect themselves from potential accidents. These designated areas are typically designed to accommodate multiple individuals, allowing them to stay safe until it is clear to return to their work. The need for such protective measures is supported by safety regulations that mandate risk mitigation in hazardous environments.

While safety helmets, guardrails, and cones to mark hazards are also important aspects of mine safety, they serve different purposes. Safety helmets provide head protection, guardrails help prevent falls on elevated paths, and cones are used for marking hazards but do not offer physical protection from potential accidents. Shelter holes are specifically designed for the protection of personnel in higher-risk scenarios commonly found in haulage-ways, making them the most appropriate form of protection in this context.
