Dual Drive Mine Door
Dual complementarity, ensuring peace of mind in emergencies
The "main drive + backup" dual-power architecture is adopted.
The main drive is suitable for frequent daily operations, while the backup drive is designed to handle unexpected situations such as power outages and malfunctions.
The switch-over is seamless and the operation is effortless.
This completely resolves the problem of sudden failure of the traditional single-drive door system, which causes work stoppage and safety hazards. It ensures the continuity of underground passage and protection.
The core structure of the dual drive mine door is made of high-strength wear-resistant steel, with a surface coated with special anti-corrosion and rust-proof coating for mines.
The driving mechanism is equipped with dust-proof and splash-proof protection, capable of withstanding a temperature range of -20℃ to 45℃ and a humidity of up to 98%.
It has no jamming even under heavy loads and high dust conditions, solving the problems of weak weather resistance and easy wear of traditional door bodies.
Precise wind control, energy conservation and efficiency improvement
Combined with the intelligent air pressure matching module, the dual drive cooperatively adjusts the closing force of the door panel.
The air leakage rate is ≤ 1.2%, ensuring stable ventilation pressure in the roadway and reducing ventilation energy consumption.
The opening/closing speed can be adapted as needed, and heavy-duty mine vehicles and pedestrians can pass through without interfering with each other, thereby improving the efficiency of underground operations.
Dual drive mine door
The two drive mechanisms operate independently and do not affect each other. The core components require no frequent maintenance. Daily maintenance only includes quarterly cleaning and status inspection, reducing the annual operation cost by 55%.
The installation adopts a modular design, eliminating the need for complex construction and renovation, and shortening the construction period by 30%, achieving a double benefit of cost reduction and efficiency improvement.

02.Can it be adapted to different tunnel dimensions in underground mines?
User Review
A coal mine operation supervisor
"The dual-drive design is extremely practical. It operates smoothly in daily use, and can quickly switch in case of sudden power failure. There's no need for dedicated personnel to be on duty, which saves a lot of manpower costs."
A safety specialist from a metal mine
"It is resistant to dust and moisture, has excellent ventilation and sealing effects, and has a fast emergency response. It has not caused any safety issues for over a year, and the cost performance is very high.
