In mining terminology, what is a "Probe" specifically used for?

A "Probe" in mining terminology is specifically used for examining gas levels within the mine environment. This tool is crucial for ensuring the safety and health of miners by detecting potentially harmful gases, such as methane or carbon monoxide. Regular monitoring of gas levels using a probe helps identify hazardous conditions before they pose a significant risk to personnel, thus allowing for necessary precautions or evacuations to be made.

The other options pertain to different functions. Measuring mineral quality typically involves sampling and assaying techniques, and surveying land surfaces is generally performed using tools like total stations or GPS equipment rather than a probe. Transporting explosives is managed through specialized containers and equipment designed to handle dangerous materials safely, which is not the role of a probe.
