[0002] In the mining and production process, mine vehicles such as mine dump trucks, mine excavators, mine loaders and the like not only bear heavy transportation and excavation tasks, but also usually operate in extreme and complex working environments, such as high temperature, dust, presence of combustible gas and the like. These environmental factors significantly increase the risk of fire, affecting the safety and reliability of the vehicle.

[0003] The causes of fire of mine vehicles are various, including but not limited to engine overheating caused by long-time overload operation of the vehicle, oil circuit or circuit fault and the like. In the mine environment, the large presence of coal dust and combustible gas provides favorable conditions for the spread of fire. In addition, the coal transported by the mine vehicle itself can also become a fire source, especially when the coal contains components with spontaneous combustion tendency, which will undergo an oxidation reaction after encountering oxygen in the air. If the heat generated is greater than the heat dissipated to the surrounding environment, heat will accumulate, causing the coal temperature to rise and reach the ignition point, thereby causing a fire.

[0004] Traditional fire prevention measures mainly configure fire extinguishers on the vehicle, however, this approach has obvious limitations. Due to the large interior cargo space of mine vehicles, and the fact that they are usually loaded with a large amount of coal or other flammable substances, when a fire occurs, the fire is often not easy to be discovered in time. Even if it is discovered, due to the possible spread of the fire, the effect of using a fire extinguisher to put out the fire is often limited, and it may even be impossible to control the fire. Therefore, the existing fire-fighting means has certain safety hazards when dealing with mine vehicle fires, and cannot effectively ensure the safety of the vehicle and personnel. SUMMARY
