Aiming at the characteristics of narrow roadway space and high concentration of toxic and harmful smoke when a mine fire occurs, the fire fighting truck provided by the invention provides a fire extinguishing device combining a high-pressure water jet system and a water mist system, and is carried on a crawler-type travelling mechanism. When a mine fire occurs, a large amount of open fire and smoke are generated at a fire point and spread to other places through a roadway. Carry out wireless control through remote control device, the crawler-type transport vechicle can be transported intelligent fire engine near the position of starting a fire rapidly. The high-pressure water jet sprayer and the water mist sprayer spray and cover the water jet and the superfine water mist pressurized by the pipeline booster pump to the ignition point. High-pressure rivers can put out to the ignition source that fires, and thin water smoke can reduce the intensity of conflagration on the one hand, and on the other hand can play the degree that the flue gas flow reverses in the control tunnel, reduces the production of combustion products and the quantity of suspended particles, reduces the effect of tunnel internal environment temperature. The invention installs a heat insulation protection plate at the front end of the fire extinguishing device to protect the fire extinguishing device and operators.
