At present, the degree of automation of mining vehicles and other heavy equipment that extract ore from the underground excavation working surface to the surface is getting higher and higher. Rock drilling rigs, scrapers, shearers, tunnel boring machines, road rollers, mining dump trucks, Highly automated vehicles and equipment such as loaders and articulated mine cars have been widely used, and the large-scale use of these equipment has also brought new challenges to the safety management of mines, especially underground mines.
Underground vehicle fires are one of the common accidents in mines. Once a fire occurs, a large amount of dust will be generated during mining, transportation, storage, etc. If too much dust accumulates, a dust explosion will occur. Moreover, the burning dust will spread rapidly, forming huge explosive energy, which can cause serious damage and casualties. Take underground coal mines as an example. There is a large amount of pulverized coal underground. In addition, there is also gas and a large amount of electrical equipment. If the fire source is not controlled in a timely and effective manner, it is very easy to cause severe fires that kill and injure many people. ACCIDENT. It can be seen that the prevention and control of underground vehicle fires is of vital importance. Taking effective measures and timely and effective emergency response is of great significance to ensure the safety of personnel and the maintenance of mining assets.
The fire extinguishing device/equipment for underground vehicles is a new type of automatic fire extinguishing system dedicated to mining vehicles. The device/equipment adopts a purely mechanical autonomous operation mode. First, it uses temperature-sensitive fire source detectors to independently monitor and identify the fire situation in each internal flammable space of the underground vehicle. Dynamically, complete timely and effective prevention of early fires in underground vehicles; secondly, through the purely mechanical linkage of components, the system is automatically activated and chemicals are released for rapid and effective fire emergency treatment. The system is designed with integrated prevention and control, and can operate completely independently of manpower. The device/equipment has fast fire response and fire extinguishing response, which can help the underground mine car to suppress the fire in the initial stage.
This device/equipment adopts electricity-free and voltage-free technology. It does not require any form of power supply for installation and operation, and there is no pressure in the normal downpipe lines. Therefore, it has better stability and lower failure rate. In addition, the components of the device/equipment are made of stainless steel with high strength, earthquake resistance, corrosion resistance, and high temperature resistance, so its service life is longer and the maintenance cost is lower. It is also more suitable for the complex and harsh operating environment of mines, and can be used for Each underground vehicle provides better fire protection technical support for autonomous fire detection and fire emergency response. In addition to the advantages of accurate detection, rapid response, effective fire control and extinguishing, intelligent fire extinguishing, safety and reliability, this device/equipment can also provide customized fire extinguishing solutions based on the vehicle model and the size of the engine compartment, fuel tank, battery box, tires, etc. The design is more consistent with the internal structure of the vehicle and has a higher degree of adaptability. Of course, the fire extinguishing effect is also better.
The introduction of fire extinguishing devices/equipment for underground vehicles has provided a new idea for fire management in mining enterprises, and also made it possible for rock drilling rigs, scrapers, shearers, tunnel boring machines, road rollers, mining dump trucks, loaders, The fire safety of mining vehicles such as articulated mine cars and heavy mobile equipment is more guaranteed. Make the safe operation of mining vehicles and the safe construction of mines a reality.
