As an indispensable mechanical vehicle for supporting mining surfaces in the production process of coal mines and non-coal mining enterprises, mining trucks effectively solve the problems of heavy workload and low efficiency in moving underground unit supports. It has the characteristics of compact structure and high integration, making it widely used in the mining field. With the enhancement of people's safety awareness and the advancement of mining intelligence, automatic fire-extinguishing devices/systems for underground mine trucks with autonomous fire-extinguishing capabilities have gradually been widely recognized by the public. It plays a very good role in preventing and controlling fires in mining vehicles such as transport machines, oil tank trucks, explosive trucks, tunnel boring machines, and rock drilling rigs.
However, due to the harsh underground mining environment and the presence of large amounts of flammable gases and dust, once a fire occurs, the fire spreads quickly and can easily cause explosions, posing a serious threat to the safety of mining companies' personnel and property. However, traditional fire extinguishing methods have the disadvantages of late detection and low fire extinguishing efficiency. Not only is the effectiveness of fire extinguishing poor, but it is also unable to achieve very early fire detection and is highly passive. Therefore, in order to ensure the fire safety of underground mine cars and mining machinery and equipment, it is necessary to adopt underground mine car automatic fire extinguishing systems/devices.
Features of underground mine car automatic fire extinguishing device/system:
1. Safety and environmental protection - water-based, perfluorohexanone, etc. are used as fire extinguishing gases. They do not cause damage or pollution to the environment or vehicles, and can be used to extinguish fires in manned environments.
2. Efficient fire extinguishing - the fire extinguishing agent will quickly vaporize after encountering a fire and quickly reduce the temperature of the fire scene. At the same time, water-based fire extinguishing agents have good permeability, can effectively adhere to the surface of combustible materials, and have strong flame retardancy and re-ignition resistance.
3. Shield thermal radiation - Fire extinguishing agents have a good shielding effect on thermal radiation, which can quickly suppress the fire and prevent the spread of the fire.
4. High reliability - the system has three modes: automatic start, manual start and emergency start, effectively ensuring the normal start of the device.
5. Long system life - the detectors, nozzles, valves, pipelines, etc. are all made of stainless steel, which has good corrosion resistance and strong stability, effectively extending the service life.
6. Instant spraying - the system will automatically start at the first moment of identifying a fire, with short response time and minimizing fire losses.
7. Strong customization - the system can be professionally customized based on actual fire extinguishing needs, protective space size, operating environment, etc. to achieve the best fire extinguishing effect.
8. Flexible control - the system can realize point-to-point precise fire extinguishing in a single space according to actual fire extinguishing needs, and can also achieve simultaneous protection of fires in multiple flammable spaces by setting different temperatures of the detector.
9. Small space occupied - Compared with traditional fire extinguishing systems, the system pipe diameter is small and can penetrate deep into small and complex spaces without occupying extra space.
10. Convenient maintenance - the system is equipped with a device self-checking function, which eliminates the need for complex maintenance processes, avoids labor cost investment, and makes maintenance simple and convenient.
It can be seen that the underground mine car automatic fire extinguishing system/device, which focuses on autonomous fire detection and fire extinguishing, plays an important role in preventing mining vehicle fires. The system can use real-time fire detection technology to detect and detect vehicle fires early, effectively control the spread of fires, reduce the probability of vehicle fire accidents, and ensure the fire safety of vehicles above and below mines, thus effectively improving mine production efficiency and economic benefits.
