Once a fire breaks out in a mine, it will not only burn a large amount of equipment and coal resources, causing losses to production, but also produce a large amount of toxic gases that will permeate the mine and cause casualties to workers. Moreover, in mines with the risk of gas and coal dust explosions, gas and coal dust explosion accidents may occur, and the harm will be even more serious. Therefore, the prevention and control of mine fires is very important.
Fires in mining vehicles such as rock drilling rigs, scrapers, trackless rubber-tyred vehicles, hydraulic excavators, tunnel boring machines, and slag trucks are one of the important factors that cause mine fires. Because these mining vehicles are exposed to high temperatures, high corrosion, and complex conditions for a long time, Working in a harsh mining environment, and often overloading, it is easy to cause the vehicle body to age, leading to electrical failures such as aging wires and short circuits in internal spaces such as the vehicle engine compartment, or oil circuit failures such as oil pipe rupture and aging seals. Or the phenomenon of coal dust, dust, and oil stains accumulating in high-temperature locations such as gearboxes, fuel tanks, and distribution boxes has become a hidden danger of vehicle fires. Therefore, fire prevention and control of mining vehicles such as rock drilling rigs and scrapers is related to the fire safety of the entire mine and is the focus of fire management for major mining enterprises.
The mine car automatic fire extinguishing system is a fully automatic fire extinguishing equipment designed to improve the fire prevention and control performance of mining vehicles such as rock drilling rigs and scrapers. This system/device can realize the full process of fire detection, early warning and fire emergency extinguishing. Operation, and through the customized system structure, it can achieve point-to-point precise fire prevention and control of various flammable spaces of mining vehicles. It not only has more efficient and accurate fire capture capabilities, but also has rapid early warning capabilities and good fire extinguishing capabilities. The probability of a minecart fire can be reduced by discovering and extinguishing the source of the fire.
This system/device is developed based on the fire characteristics, structural characteristics and practical application environment of mining vehicles such as rock drilling rigs and scrapers, and integrates more than 20 years of mining firefighting experience and multiple mining vehicle fire cases. Therefore, It has obvious advantages in performance, product structure and overall cost-effectiveness:
1. Close and accurate detection
The fire source detector of this system can be directly distributed in the prone space of mining vehicles, and the trigger temperature value can be set differentially according to the characteristics of space fires. The detector is sensitive to temperature, especially concealed fires and deep fires, and the detection results are more accurate. , the response is also faster. Moreover, 24-hour uninterrupted fire detection can grasp the fire dynamics in real time and prepare for early fire extinguishing.
2. The system adopts a no-electricity and no-voltage design, which has better stability and safety.
The system completely gets rid of its dependence on power supply, so neither power outage nor the stability of power supply will affect the operation of the system, and it also helps mining companies save energy and costs. The pressureless design ensures the safety and stable performance of the system, and there is no need to worry about system failure due to pressure loss.
3. Fully automatic and unmanned operation
Realize the transformation from passive fire prevention to active fire prevention and control of mining vehicle fires, so that mining vehicles can receive all-round fire safety protection when unattended.
4. Anti-corrosion and durable material, lower maintenance cost
This system/device uses stainless steel core components. In addition to having good earthquake resistance and corrosion resistance, it is also easy to install and maintain, and can even be maintenance-free for 5 years.
