Mining equipment shall not be parked within how many feet of a check curtain or a fly curtain?

• A. Five (5) feet
• B. Fifteen (15) feet
• C. Ten (10) feet
• D. Twenty (20) feet

Answer: (B)

Ventilation control and safety around the face depend on keeping curtains functioning and unobstructed. Check curtains and fly curtains direct and contain airflow to manage ventilation and protect the working area from gas buildup and dust. If equipment is parked too close, it can hit or tear the curtain, block airflow, or create movement hazards near the curtain, compromising safety and ventilation effectiveness. A fifteen-foot clearance provides enough space for the curtain to operate properly and for workers and equipment to maneuver safely. That’s why the standard is fifteen feet.
