Which description correctly describes a check curtain?

• A. A curtain permanently installed to stop air flow
• B. A curtain used to seal gas leaks
• C. A temporary curtain erected to deflect air and can be traveled through by mobile equipment and miners
• D. A device that lights the face

Answer: (C)

Ventilation control in the mine relies on flexible, temporary barriers that can be positioned as work progresses. A check curtain is exactly that kind of barrier: a temporary curtain erected to deflect the airflow around a work area, while still allowing miners and mobile equipment to pass through. This lets you redirect the air where it’s needed without creating a permanent stoppage, and you can move or remove it as conditions change. It’s not used to seal gas leaks, nor is it a device for lighting the face.
