Inflatable Stopping for mine or tunnel barricade
Each stopping / barricade can be folded, stored on a warehouse shelf and transported to the work location as a compact package. Simply at-tach to corner eyebolts or fold out in the drift, connect valve up to air bottle or compressed air via a reducer valve and inflate. Once fully erected, secure the barricade to the back and walls by the quick snap on buckles. In the picture there is a double door to allow personnel to enter or exit the blocked-off area. The door is held closed by Velcro strips on the sides and the bottom and provides blast damage relief in areas close to main excavations.
