In the complex and huge operation system of the coal mining industry, underground mine cars are an indispensable "lifeline" for key operations such as coal transportation. Their efficient operation ensures the smooth connection between coal mining and transportation. However, the underground environment is harsh and complex. High humidity can easily corrode the electrical and metal parts of the mine cars. High dust can easily cause static electricity or friction fires. The narrow space and limited ventilation make it difficult for the heat and toxic gases of the fire to spread. Once a mine car catches fire, it will not only cause equipment damage and production stagnation, but it is also likely to trigger chain disasters such as gas explosions, seriously threatening the lives of miners and causing immeasurable losses to coal mining companies.
Under this severe situation, the Jiutong Changsheng mechanical passive automatic fire extinguishing technology developed by Shandong Zhongdao Fire Protection has brought a major breakthrough in the fire safety of underground mine cars. This technology breaks through the traditional fire extinguishing system's dependence on external power supplies, complex electronic control systems, etc., and based on unique mechanical principles and physical properties, it realizes rapid and accurate detection and efficient fire extinguishing of mine car fires. It fundamentally improves the fire prevention and control capabilities of mine cars, provides reliable safety protection for underground mine cars in coal mines, redefines the industry standards for fire safety of underground mine cars in coal mines, and plays a vital role in ensuring safe production in coal mines.
01
Zero dependency: free from constraints, stable and reliable
Traditional mine car fire extinguishing systems mostly rely on external power supplies, electronic components or complex control systems. In the harsh environment underground, these dependent factors constitute a major weak link in the reliable operation of the system and become a key bottleneck restricting the stable performance of the system. Power failures, damage to electronic components due to moisture, and control system failures frequently occur, causing the fire extinguishing system to "fall off the chain" at critical moments and fail to play its due role.
Jiutong Changsheng's mechanical passive automatic fire extinguishing technology completely gets rid of these constraints. It does not require an external power supply, and can achieve fire detection and fire extinguishing functions only by relying on mechanical principles and physical properties. The system's built-in temperature sensing elements and mechanical trigger devices can accurately sense temperature changes and respond in a timely manner without power support. This zero-dependency feature enables the system to maintain high stability and reliability under various extreme conditions underground, just like a complete and reliable protection mechanism, continuously building a solid line of defense for the fire safety of mine cars.
02
Strong protection: precise, efficient and comprehensive coverage
Early detection and rapid disposal of fire are the key to ensuring the fire safety of mine cars. Jiutong Changsheng's mechanical passive automatic fire extinguishing technology has a strong fire detection capability. Its high-precision temperature detectors can monitor the temperature changes inside the mine car in real time, and are reasonably distributed to cover all key parts of the mine car, leaving no potential fire hazards undetected.
Once an abnormal temperature rise is detected, the system will instantly trigger the fire extinguishing procedure. The fire extinguishing agent is sprayed to the fire source in a uniform and efficient manner through a customized nozzle, quickly reducing the temperature of the fire scene and interrupting the combustion reaction. Compared with traditional fire extinguishing methods, this technology is faster and more effective in extinguishing fires. It can control the fire in the early stage of the fire, effectively prevent the spread and expansion of the fire, and provide all-round and powerful protection for the safety of mine cars and personnel.
03
Innovative design: tailor-made to meet your needs
There are many types of underground mining vehicles with different specifications. Different mining vehicles such as explosion-proof rubber-wheeled trackless vehicles, manned vehicles, scrapers, monorail cranes, drilling trolleys, and support transporters also have differences in working scenarios and fire risks. Jiutong Changsheng is well aware of this and provides a customized design solution for the passive automatic fire extinguishing system.
The technicians will tailor the most suitable fire extinguishing system solution according to the specific conditions of the coal mine, including the model, size, running route, working environment and other factors of the mine car. From the installation location and number of detectors and nozzles to the selection and dosage of fire extinguishing agents, they are all precisely designed and configured to ensure that the fire extinguishing system can meet the fire safety needs of the coal mine to the greatest extent and perfectly adapt to each mine car, thereby providing it with the most effective fire protection.
04
Leading change: setting the benchmark and driving development
The emergence of Jiutong Changsheng's mechanical passive automatic fire extinguishing technology not only provides a reliable solution for the fire safety of underground mine vehicles in coal mines, but also sets a new benchmark in the industry. With its innovative advantages of zero dependence and strong protection, it breaks the limitations of traditional fire extinguishing technology, not only providing a solid guarantee for the fire safety of underground mine vehicles in coal mines, but also leading the field of coal mine fire safety to a new height with innovative concepts and technological breakthroughs, becoming a key technical force to promote the safe and efficient development of mines.
