Mine fire or gas leak, for fast plugging mine tunnel, isolated from the air into the fire area, and the fire quickly extinguished hypoxic zone, in addition to quickly block the gas fleeing into the safety zone. At the same fire zone or gas leakage area can quickly evacuate quickly sealed by bladder-type safe passage. Balloon-type fast using high strength biaxially confined to fireproof PVC material, its warp and weft tensile strength ≥2500N / 5cm, tear strength ≥400N, much larger than the national standard. Material has significant integrated features: fire retardant, wear-resistant, anti-aging, soft, arbitrary folded, the coating does not fall off, high and low temperatures. The balloon-type fast closed with a light weight, simple operation, using a wide range from roadway geometry, frame type of restrictions, arbitrary strong, its fire-retardant materials antistatic, impact, flexibility and other notable features . System configuration: sealing bag, composite cylinders, inflatable joints, safety valve, inflatable high-pressure pipeline, the release valve.
