What is a manhole in the context of mining?

In the context of mining, a manhole refers specifically to a hole that is cut into the mining structure to allow a person to pass through while trips, or trains of coal cars, are moving by. This design facilitates the movement of personnel without interruptions to the flow of equipment and materials in the mine. It is essential for ensuring safety and efficiency within the mining operations, as it allows miners to move between areas of the mine without needing to halt production or interfere with equipment operation.

The term distinguishes this kind of opening from other types of access points like ventilation shafts or emergency exits. Understanding the design and purpose of a manhole is crucial for anyone working or training in the mining industry, as it highlights important safety protocols regarding personnel movement and the operational layout of the mine.
