A parachute-type mine stopping used in ventilation control comprises a parachute-like canopy suspended from straps or lines secured to a roof bolt or the like. After the lines are so secured, the stopping is erected by merely lifting the upper edge of the canopy into the airstream in the passage, the airstream causing the canopy to simply 'pop' into place. In a preferred embodiment, a skirt is sewn to the peripheral edge of the canopy to improve sealing.
