Mine-Specific Structural Design
Door Leaf:
Constructed from 12mm Q690 high-strength alloy steel with internal reinforcing ribs and optional flame-retardant filling, the door leaf is designed to resist deformation, withstand 0.4MPa pressure and explosion shock, eliminating the risk of structural failure under extreme conditions.
01
Door Frame:
Featuring an integrated steel-welded structure with embedded steel plate fixation, the door frame enhances stability to bear long-term wind pressure and impact loads, preventing the deformation that compromises sealing performance.
02
Sealing System:
A silicone + wear-resistant rubber composite seal ensures a leakage rate of ≤2%, supported by an intelligent wind pressure adaptive system that automatically adjusts sealing pressure. This balances ventilation efficiency and airtightness, guaranteeing no air leakage even in high-wind-pressure metal mines.
03
Opening/Closing Mechanism
Driven by a mine-specific explosion-proof energy-saving motor (≤500W working power) paired with a reduction gearbox, the door operates smoothly. A manual emergency handle is provided for power outage scenarios, with a buffer design to prevent collision damage.
The PLC-based control unit features anti-electromagnetic interference design, supporting local/remote control and data upload. It ensures stable signal transmission in complex underground electromagnetic environments and is fully compatible with mine intelligent management systems.
Meets international mine safety standards, with emergency quick-release mechanisms for blast scenarios.
Trusted Compliance & Proven Performance
Our doors hold overseas mine explosion-proof certifications and comply with international ventilation standards, simplifying safety audits for global projects. The structure has been validated in high-humidity, high-dust, and high-wind-pressure underground environments, with a proven track record of withstanding vehicle collisions and corrosion.
