Which item is described as a temporary curtain erected to deflect air and can be traveled through by mobile equipment and miners?

• A. Brattice
• B. Face curtain
• C. Check curtain
• D. Barrier curtain

Answer: (C)

Airflow control in underground mines is managed with curtains that shape where the air goes. A check curtain is a temporary, movable curtain erected to deflect the air stream as needed, such as directing or splitting airflow around a working area. Because it’s designed to be moved and made of lighter material, miners and mobile equipment can pass through it without removing it, keeping the ventilation flexible while maintaining air deflection. In contrast, a brattice mainly directs air toward a face and is typically set up as more of a fixed ducting element; a face curtain is used at the face to regulate air close to that opening; a barrier curtain serves as a more permanent obstruction to stop air from entering a certain area and isn’t meant to be travelled through.
