How many entries are designated as escapeways from the working section to the nearest available opening on the surface?

How many entries are designated as escapeways from the working section to the nearest available opening on the surface?

• A. One (1)
• B. Two (2)
• C. Three (3)
• D. Four (4)

Answer: (B)

In underground mining, you must provide two escape routes from every working section to the surface. This setup creates a second, independent path so that if one route is blocked by a collapse, fire, or other hazard, miners still have a safe way out. The question is asking how many entries are designated as escapeways to the nearest surface opening, and the minimum required is two. Having two routes ensures redundancy and improves the chances of timely egress in emergencies. While more than two can exist, two is the standard minimum that answers the requirement.
