When a communication signal is received on the working section, which device is activated?

• A. The mine phone
• B. A surface alarm beacon
• C. The ventilation fan controller
• D. The hoist control room

Answer: (A)

When a signal is sent from the working section, the mine phone is the system designed to handle that communication. It activates to establish a two-way voice link between the face and surface or other parts of the mine, allowing the crew to report conditions, request assistance, or coordinate tasks quickly. The other devices serve different roles: the surface alarm beacon is for emergency alerts, the ventilation fan controller adjusts airflow based on ventilation needs or safety signals, and the hoist control room manages hoisting operations.
