ZHJ Series Mine-Use Mobile Firefighting Grouting Equipment
The ZHJ series mobile fire-prevention grouting equipment for coal mines can be deployed in underground working faces and goaf areas where coal spontaneous combustion poses a risk, serving as a device to inject slurry-like materials—such as water-based mud, fly ash slurry, lime slurry, and chemical gels—or even higher-viscosity liquids, including concentrates containing mechanical impurities and solid particles—for fire suppression. By utilizing inorganic mineral materials, this equipment effectively fills areas prone to spontaneous combustion underground, absorbing the thermal energy released from oxidizing coal, inhibiting further oxidation of coal, and sealing off airflow pathways—all critical functions that help prevent fires.

Mining Fire Prevention Grouting Device 500-9
The ZHJ series mine fire prevention grouting device uses a motor as the power drive and employs fully hydraulic S-pipe valve switching technology. It can continuously and uninterruptedly deliver slurry such as concrete and other mixed liquids to the required location at very high pressure. This pump is suitable for underground coal mines, tunnels, mines, national defense projects, and construction environments where flammable gases exist and explosion-proof requirements are needed.

Mobile Fire Prevention and Extinguishing Grouting Device for Mining ZHJ-600-3.5
The ZHJ series mine fire prevention and extinguishing grouting device can be used at coal mine working faces and goaf areas with the risk of spontaneous coal combustion as a fire prevention and extinguishing equipment that sprays slurry and lime slurry using water as the conveying medium. It utilizes inexpensive inorganic mineral materials to effectively fill areas of spontaneous combustion underground, with multiple fire prevention and extinguishing functions such as absorbing the heat energy of oxidized coal, preventing coal oxidation, and blocking air leakage channels.

This pump uses electricity as the power drive. The process of aerosol retardant fire prevention and extinguishing involves converting a retardant aqueous solution under certain pressure into an aerosol through an atomizer. The tiny droplets sprayed by the aerosol generator can drift with the air leakage flow to any place in the goaf where air leakage occurs, thereby achieving comprehensive fire prevention in the goaf. When mining self-igniting single coal seams or multiple layered coal seams, using retardant solution for fire prevention by spraying the retardant solution onto residual coal in the goaf to suppress spontaneous combustion of residual coal is an effective method.
