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.
