How far from the face must powder boxes or magazines be kept?

The requirement for keeping powder boxes or magazines at least 100 feet from the face is rooted in safety protocols designed to minimize the risk of explosive incidents during mining operations. This distance helps ensure that any potential accidental detonation will not affect personnel working at the face, which is often the most hazardous area of the mine.

Maintaining this distance also provides a buffer zone that allows for safer handling and storage of explosive materials. By ensuring that powder boxes or magazines are set back at least 100 feet, the regulations reflect a balance between operational efficiency and the critical need to protect workers from the dangers associated with explosives.

The specified distance also aligns with best practices in mine safety, which are informed by years of research and incident analysis. Adhering to this standard helps foster a culture of safety within the mining environment, ensuring that proper precautions are taken to limit exposure to potential hazards.
