The main issues facing the fire safety of open-pit mine trucks such as articulated mine cars, shearers, scrapers, wide-body dump trucks, support trucks, flatbed transport trucks, trackless rubber-tyred trucks, etc.:
1. Mine car fires often occur in compact and airtight places. It is difficult for personnel to observe and detect the fire in time. Moreover, it is impossible to quickly and efficiently extinguish the fire immediately during the operation of the vehicle. It is highly dependent on personnel and has excellent autonomous performance. It cannot meet the development needs of intelligent and efficient mines.
2. The high intensity and frequency of open-pit mine car operation, coupled with the extreme temperatures of the mine and the complex working environment of high corrosion and high vibration, make the internal lines and equipment of the vehicle aging and severely corrosive, exacerbating the mine car fire accident. happened.
3. Most mining cars are expensive to build and require large investment by enterprises. Once a fire occurs, it will not only cause heavy property losses, but also seriously put mining companies at risk of suspending operations for rectification. Fires are highly hazardous.
The automatic fire prevention and extinguishing system for open-pit coal mine vehicles is based on a full analysis of the operating environment and fire characteristics of mine vehicles, combined with fire extinguishing technology, and relies on smart mine fire extinguishing technology to shorten fire detection time and improve vehicle fire extinguishing efficiency. Through intelligent detection , data transmission, cloud computing, big data and sprinkler fire extinguishing and other key technologies, thereby realizing real-time online monitoring, early warning and fire extinguishing of fires in flammable areas of vehicles, thereby realizing the stability, reliability, intelligent and seamless control of fires in mining vehicles. Humanized fire extinguishing solutions.
This system effectively meets the fire protection needs of mining vehicles for “small, early, and early stage” firefighting, and at the same time has made new breakthroughs in the safety and automation of system applications:
1. Electrical-free fire extinguishing technology - realizes the purely mechanical self-care operation of the system, gets rid of the constraints of manpower and circuits, realizes real-time protection of vehicle safety, and effectively improves the stability and reliability of the fire extinguishing system.
2. Stainless steel structure + electroplating anti-corrosion - effectively prolongs the service life of the device and ensures the stability of the system operating in complex mining conditions.
With the rapid development of mine mechanization, intelligence, and unmanned operations, and the continuous development and integration of new technologies such as big data, cloud computing, Internet of Things, and artificial intelligence with traditional fire extinguishing systems, the construction of smart fire protection in mines will further move towards unmanned and unmanned operations. Developing in the direction of high efficiency and autonomy, it will continue to be used in automatic fire prevention and extinguishing of various special vehicles such as mines, ports, airports, and oil fields.
