During pillar extraction, where should non-essential personnel remain?

In the context of pillar extraction, the safety of personnel is paramount due to the inherent risks associated with mining operations. Non-essential personnel should remain outby the last open crosscut to ensure they are at a safe distance from potential hazards. The last open crosscut serves as a boundary beyond which the extraction of pillars can lead to unstable conditions, making it critical for non-essential workers to stay beyond this point.

Staying outby this area minimizes the risk of exposure to falling rock or other dangers that may arise during the extraction process. It also emphasizes the importance of having trained and essential personnel who are equipped to handle emergencies should they arise during the operation. In contrast, remaining in the extraction site, inside mining equipment, or in a designated safety zone could put non-essential personnel at greater risk, depending on the specific circumstances related to pillar extraction activities.
