Against the backdrop of accelerated transformation of the global energy structure and the guidance of the "dual carbon" target, mining, as a traditional high energy consumption and high emission industry, is undergoing profound changes in green and low-carbon development. The widespread application of new energy mining cars has injected new impetus into the sustainable development of mines, but the accompanying fire safety challenges are becoming increasingly prominent. The automatic fire extinguishing system for mining cars (GMfire intelligent special fire prevention and extinguishing solution) is gradually becoming a standard configuration for the safety of mining vehicles due to its intelligent and efficient characteristics, providing a solid guarantee for the upgrading of mining safety.

1、 The complexity of fire hazards in mining vehicles

The mining operation environment is complex and harsh, with dark and humid underground and narrow tunnels, while open-pit mines face extreme conditions such as wind, sun, high temperature, and high dust. Mining vehicles operating at high loads for long periods of time in such environments face multiple fire hazards:

Power system risk: The lithium battery of the new energy mining car is prone to fire or even explosion when subjected to compression, overheating, short circuits, and other conditions.

Traditional vehicle hazards such as failed fuel line seals and damaged insulation layers of power lines can become ignition hazards. The high temperature in the engine compartment and hydraulic system leaks also pose a threat to the safety of mining vehicles.

Environmental factors: Adverse conditions such as high temperature, dust, and high humidity can accelerate the aging of vehicle components and increase the likelihood of fires. In confined spaces underground, fires may also cause secondary disasters such as gas explosions, with unimaginable consequences.

2、 Technological breakthrough in automatic fire extinguishing system for mining cars

Faced with the complexity of fire hazards in mining vehicles, traditional firefighting methods are no longer able to meet the needs of efficient and safe firefighting. The automatic fire extinguishing system for mining cars has emerged, which integrates advanced intelligent special fire extinguishing technology and achieves a fundamental transformation from "passive response" to "active protection".

（1） Intelligent fire monitoring and early warning

The system adopts a multi-sensor network and arranges temperature detectors, flame sensors, and smoke sensing devices in key parts of the vehicle to form an all-weather fire monitoring system. For example, point type temperature detectors can provide 24-hour real-time monitoring of flammable areas such as battery compartments and motor compartments. Once temperature anomalies are detected, they will respond within milliseconds, trigger warning devices, and initiate fire extinguishing procedures. This extremely early intervention capability can significantly reduce fire losses.

（2） Efficient and precise fire extinguishing mechanism

Diversified selection of fire extinguishing agents: For different types of fires, the system can choose water-based fire extinguishing agents, ultra-fine dry powder fire extinguishing agents, perfluorohexane fire extinguishing agents, etc. Water based fire extinguishing agents have multiple fire extinguishing effects such as cooling, oxygen isolation, and suffocation; Ultra fine dry powder fire extinguishing agent can quickly cover the fire source and suppress combustion reactions; Perfluorohexane fire extinguishing agent has become an ideal choice for electrical equipment fires due to its excellent fire extinguishing performance and good electrical insulation.

Fine spray technology: The system adopts fine spray nozzles with a spray angle of up to 120 °, which can evenly release fire extinguishing agents in the form of small particles to the fire source. The agent absorbs a large amount of heat during the gasification process, rapidly reducing the temperature of the fire and forming an oxygen barrier to achieve suffocation and fire extinguishing. This targeted fire extinguishing method significantly improves the utilization rate of chemicals and greatly reduces the cost of single fire extinguishing.

（3） No electricity, no voltage, pure mechanical self starting design

The system abandons the traditional design of fire equipment relying on electricity and adopts a fully automatic working mode without electricity or voltage. Normalizing the pipeline without pressure avoids system failure caused by insufficient or lost pressure. When a fire occurs, the system uses a pure mechanical linkage mechanism to instantly activate and release the medication, without the need for manual intervention or external power support, truly achieving all-weather and all time autonomous fire protection.

（4） Customized design and modular configuration

The system can be customized according to the structural characteristics and fire risk areas of different types of mining vehicles. A professional team will plan the installation positions of detectors and nozzles reasonably based on the actual situation of the vehicle, ensuring that the fire extinguishing device can accurately locate the fire source and achieve efficient point-to-point fire extinguishing. At the same time, the system adopts a modular design, and components such as medication bottle groups and pipeline lines can be flexibly supplemented and replaced according to actual needs, with strong adaptability.

In short, as the intelligent guardian of mining vehicle safety, the automatic fire extinguishing system for mining cars is driving the mining industry towards a safer, more efficient, and sustainable direction with its outstanding performance and innovative technology. Under the guidance of the "dual carbon" goal, this system will contribute more to building a green and low-carbon society.
