What is a check curtain?

• A. A permanent curtain that blocks air flow
• B. A temporary curtain erected to deflect air and can be traveled through by mobile equipment and miners
• C. A curtain that seals gas leaks
• D. A decorative cloth used in the mine

Answer: (B)

In underground mine ventilation, a check curtain is a temporary, movable barrier that is put up to deflect or steer the air flow rather than permanently block it. It’s designed so miners and mobile equipment can pass through it while still directing ventilation where it’s needed, such as around a working face or through a crosscut. This distinguishes it from a permanent curtain that would block air for good, from devices that seal gas leaks, and from decorative cloths. The key idea is flexibility: you can set up, move, or remove a check curtain as work progresses to maintain proper air distribution.
