An adit stamp is a mark, often a physical impression or an inscription, used to verify and authenticate access or entry to a specific location, typically an underground mine. It serves as a record of authorized personnel or equipment entering and exiting the adit, or horizontal mine entrance. For example, a metal tag with a unique identifier might be affixed to a board each time a miner enters, providing a visual record of who is underground.
The use of such a system provides crucial benefits in ensuring worker safety and accountability within potentially hazardous environments. It aids in monitoring the number of individuals present during shifts, facilitating emergency response in the event of accidents or disasters. Historically, these systems have evolved from simple physical markers to more sophisticated electronic tracking mechanisms, reflecting advancements in safety and monitoring technology within the mining industry.
