Coned Parachute – Flexible Stoppings
Coned Parachute Stoppings are used to provide an effective temporary vent control, often used for sealing off old stopes and creating temporary vent circuits. The cone shape of the parachutes is designed to create a better seal in the drive, providing up to a 95% effecting seal.
All Parachutes are manufactured from high wear material, additional webbing reinforcement can be included for higher situational pressures.
Standard Coned Parachute sizes

Parachutes can be manufactured to suit specific tunnel profiles or pressure capacities.
Flat Parachute Stopping
