Rock drilling rigs are used in the underground mining operation cycle. After blasting, broken and unstable pumice must be removed from the roof and two gangs of the working site to ensure the safety of on-site workers and equipment. Mining transport trucks are also called underground mining trucks, unlike dump trucks and underground mining trucks. Both of these models are mining auxiliary equipment widely used in mining and production. With the further development of mechanization of mining engineering, the demand for rock drilling rigs and mining transport vehicles in mining areas is increasing day by day. And it has become an irreplaceable key auxiliary equipment for transportation and mining in mining areas. However, due to the special environment of mines such as high temperature, high corrosion, high dust, complex and changeable ground road conditions, and large distribution of combustible combustion-supporting materials, fire accidents have become a key factor threatening the efficient production of rock drilling rigs and mining trucks. This has promoted various Large mining companies pay more attention to the fire safety management of rock drilling rigs and mining trucks.
The special operations of high temperature, high corrosion and high coal dust in mines place higher requirements on the fire extinguishing equipment of mining vehicles. There are often flammable and explosive gases and dust inside mines, which can easily cause explosions in the event of a fire. Especially in underground mines, the space is narrow and the road conditions are complex. Mining vehicles are prone to friction with other obstacles during driving, causing wear and tear, causing oil leakage and electricity leakage. Then, after long-term operation, the mechanical parts generate high temperatures and cause fire accidents. Such fires often It is sporadic and concealed, and is difficult to detect especially when mining vehicles are in operation. Once a mining vehicle catches fire, the fire spreads rapidly, is difficult to control, and rescue conditions are limited, often resulting in huge losses. Therefore, the fire extinguishing devices required for the prevention and control of mining vehicle fires need to be highly automated and able to adapt to the extreme operating environment of mines and have the comprehensive protection functions of early fire monitoring, independent fire warning, and sprinkler fire extinguishing.
The mine car automatic fire extinguishing system is specially developed to ensure the safe production of mining vehicles. It mainly uses fast and accurate fire detection technology to monitor and detect internal fires in single or multiple flammable spaces of mining vehicles to achieve mining Prevent vehicle fires, and complete early warning and automatic sprinkler fire extinguishing of mining vehicle fires. This system/device has very obvious application advantages compared with traditional handheld fire extinguishers:
1. Fully automated operation: Once the system is installed, it will automatically enter the safety protection mode for mining vehicles. It can independently complete fire monitoring and fire capture, fire early warning, and self-starting fire extinguishing. The entire process is purely mechanical linkage operation, without the need for No human intervention is required and no power source is required.
2. Accurate detection and fire extinguishing: The system can directly realize point-to-point accurate detection of flammable spaces in mining vehicles and point-to-point accurate fire extinguishing. The detector is good at capturing deep-seated fires and hidden fires, and can quickly capture fires as soon as they occur. source, and activate the system early warning and fire extinguishing to control the fire in time.
3. All-round real-time protection: The fully automatic mode of the mine car automatic fire extinguishing system completely gets rid of the shackles of humans on the system, and also allows unattended mining vehicles to be effectively protected, which is of great significance to the prevention and control of mining vehicle fires. .
4. Safe and efficient fire extinguishing: The mine car automatic fire extinguishing system uses water-based fire extinguishing agents and fine spray technology, which can quickly release the fire extinguishing agent to the fire source over a larger area, effectively control the fire, prevent the fire from spreading further, and at the same time extinguish the fire. The agent is environmentally friendly and safe and will not cause secondary damage to equipment or people.
Mine car automatic fire extinguishing systems are of great significance to protecting mine car fire safety. It can provide timely and effective fire extinguishing measures to prevent explosions caused by fires and further damage to the mine environment. At the same time, the mine car automatic fire extinguishing system can also reduce the risk of casualties of miners and ensure the safe production of mines. Moreover, the application of this system can also help promote safe production in mines. By reducing the occurrence of fire accidents, we can improve mine production efficiency and reduce production downtime and economic losses caused by fire accidents. At the same time, the mine's safety reputation can also be improved.
