In order to better adapt to the needs of the mining industry, underground mine cars have begun to gradually develop in the direction of low carbon, environmental protection, health, and safety. The operation of these mine cars has its own unique features, such as many points and a wide range. These characteristics simultaneously It determines the difficulty of safety management of underground mine cars, and the vehicle body structure itself has a certain degree of complexity. These complexities also determine that fire management of mine cars has become the most difficult problem in underground mine car management, such as hidden, difficult to discover, Difficult to locate, difficult to rescue, etc. Therefore, the first priority for underground mine car safety management is fire safety management.
Underground mine car fires are one of the common fires in mines. Once a fire occurs, it will cause serious damage to mine equipment and workers, and will also cause immeasurable economic losses. At the same time, a large number of synthetic materials are used in the manufacturing and production of mine cars. Therefore, toxic gases are often produced when a fire breaks out. These toxic gases will also pollute the surrounding ecological environment. Therefore, an effective method is needed to solve the problem of underground mine car fires.
The underground mine car automatic fire extinguishing system is a special automatic fire extinguishing device/equipment for mine cars that uses water-based fire-extinguishing agents with better flame retardant properties. The system adopts a non-electric and voltage-free fully automatic intelligent protection mode. Once the system is installed, It can automatically enter the mine car fire safety protection state. The system first uses temperature-sensing fire source detection technology to realize real-time detection of fire dynamics in various flammable spaces inside the mine car, and detects fire sources distributed in each flammable space. The preset value of the detector triggers the temperature to identify the fire situation and take early precautions against mine car fires. Then, the system completes the linkage of each component of the system through pure mechanical starting technology. When the fire source detector determines the fire situation, it will activate the starting device and early warning device through the rupture of the thermal element, and then directly make an early warning response and start the system release Drug reaction. Finally, after the system releases the agent, under the action of fine spray technology, the water-based fire-extinguishing agent is evenly released in the form of fine water mist over a large area above and inside the fire source, and then reaches the target through physical and chemical effects. The goal of rapid cooling and oxygen isolation is to extinguish the fire quickly and avoid greater losses caused by the spread of the fire.
The automatic fire extinguishing system can be customized according to different vehicle models. Therefore, in addition to being an important device/equipment for underground mine car fire prevention, it can also be used on heavy mobile equipment in the fields of petroleum, ports, agriculture and forestry, engineering projects, etc. In addition, the water-based fire extinguishing agent used in the system is safe and environmentally friendly. It is not only non-toxic and fluorine-free, but the fire-extinguishing residues can also be decomposed naturally. Therefore, it is favored by relevant enterprises in various fields. In Germany and Europe, this system is also widely installed and used as a standard fire protection product on heavy mobile equipment in various fields.
Why can this system be used as a standard product for coal mine fire protection?
1. Compared with other fire extinguishing devices/equipment, this system is highly integrated with the fire prevention and control functions of fire detection, fire early warning and sprinkler fire extinguishing, and can achieve a full-chain solution to underground mine car fires.
2. The system adopts a purely mechanical start-up design without electricity and voltage. No power supply is required, which facilitates the installation of the system and reduces the system energy consumption and failure rate; it is voltage-free, making the system operation safer; mechanical start-up improves the system response speed and fire extinguishing. The efficiency, of course, also reduces the investment in labor costs, and also increases the safety of rescuers in the event of a fire.
3. Taking into account the harshness of the mining operating environment, the system components are made of earthquake-resistant and corrosion-resistant stainless steel, which not only has low maintenance costs, but also has a long service life.
