In today's rapidly developing smart and green mines, new energy vehicles such as electric loaders, electric loaders, new energy mining trucks, and rock drilling rigs have gradually taken over the mining operations of coal mines, copper mines, and other mines. Faced with the increasing number of new energy mining trucks, the issue of fire safety protection has gradually become apparent, becoming the primary challenge for fire safety construction in mining enterprises such as Xinjiang and Shaanxi. The Jiutong Changsheng New Energy Mine Car Automatic Fire Extinguishing System has emerged, standing at the top of mine fire safety with intelligence, technology, and safety, becoming a landmark fire extinguishing product for solving the fire safety of vehicles in open-pit/underground coal mines and non coal mines.

Fire hazards of new energy mining trucks

New energy mining trucks mainly use lithium batteries as power sources. Compared with traditional fuel mining trucks, they have almost zero emissions during operation, greatly reducing pollution to the mining environment. However, the battery system of new energy mining cars is relatively complex, and lithium batteries are prone to thermal runaway when subjected to impacts, overcharging, overdischarging, short circuits, or high temperature environments. Once thermal runaway occurs, the internal temperature of the battery will rise sharply in a short period of time, reaching over 500 ℃, which can lead to combustion and explosion. In addition, frequent vibration, high dust concentration, humidity changes, and aging of electrical circuits during underground operations of mining cars can all lead to electrical failures and become the trigger for fires. 

Intelligent monitoring and rapid response of automatic fire extinguishing system

The automatic fire extinguishing system for new energy mining cars is a highly integrated and effective fire extinguishing device. The system adopts advanced temperature detection technology, with high sensitivity and accuracy in fire detection, and can monitor key parts of the mining car in real time, such as the battery compartment and electrical equipment compartment. Its temperature detector adopts high-precision thermal sensing elements, which can capture abnormal signals at the first time of temperature changes. 

When the temperature exceeds the normal range and reaches the set warning threshold, the temperature detector will quickly react, trigger the alarm device, emit a sharp alarm sound, and remind surrounding personnel to pay attention to safety. At the same time, activate the fire extinguishing device and accurately release the fire extinguishing agent to the fire location through the customized fire extinguishing pipeline, ensuring the rapid and effective extinguishing action. This process, from detecting the fire signal to activating the fire extinguishing device, only takes a few seconds to extinguish the fire before it spreads, greatly reducing the losses caused by the fire.

Customized design and efficient fire extinguishing

The new energy mining car automatic fire extinguishing system also has a highly customized design. The system can arrange detectors and fire extinguishing devices reasonably according to the actual usage environment and characteristics of the mining car. For example, for new energy mining cars, the system will increase monitoring of key parts such as power lines to cope with their complex fire risks. At the same time, the system can also provide targeted fire solutions for different devices. Whether it is the system pipeline structure, component quantity, or parameter settings, they can better match the internal structure and fire protection needs of new energy mining cars, achieving point-to-point precision protection for different spaces. 

In the selection of fire extinguishing agents, the automatic fire extinguishing system for new energy mining vehicles also fully considers fire extinguishing efficiency and safety. Common fire extinguishing agents include water-based fire extinguishing agents, perfluorohexane fire extinguishing agents, etc. These agents have the advantages of extremely high fire extinguishing efficiency, rapid reduction of flame temperature in a very short period of time, and inhibition of combustion reactions. 

Dealing with the challenges of complex environments

The complex and harsh mining environment, high vibration, high corrosion and other factors pose severe challenges to the stability and reliability of equipment. The automatic fire extinguishing system for new energy mining cars has fully considered these factors in its design, and the core components of the system have been comprehensively upgraded. The detector, nozzle, and medication bottle are all made of stainless steel material, which has strong corrosion resistance and can effectively resist the erosion of corrosive substances in the mining environment. At the same time, the system has also carried out anti vibration, high temperature and other protective treatments on each component, so that it can adapt to the frequent vibration of mining vehicles during driving and the high temperature environment underground. Even under extreme conditions, the automatic fire extinguishing system can work normally, unaffected by external environmental interference, and always maintain efficient detection and extinguishing capabilities. 

conclusion

The automatic fire extinguishing system for new energy mining vehicles provides strong protection for the fire safety of support trucks and other new energy mining vehicles with its advantages of intelligent monitoring, fast response, customized design, and efficient fire extinguishing. The system can perceive fire hazards in real time and deal with them in the first time, effectively improving the fire safety level of new energy mining vehicles such as support trucks and reducing the occurrence of fire accidents. In the future, with the continuous innovation of technology and the expansion of application scope, the automatic fire extinguishing system for new energy mining cars will also play a significant role in industrial vehicles such as mines, ports, airports, and oil fields, promoting the development of the industrial sector towards a safer, greener, and more sustainable direction.
