Mining funnel feeding grouting pump
The mine funnel-type feeding grouting pump is suitable for well construction in mines, as well as for ground and underground water plugging and high-concentration cement slurry injection. This pump can also be used for coal seam grouting or injecting other non-corrosive media, and even for sealing boreholes during coal mine gas drainage operations. Thanks to its excellent self-priming capability from the funnel feed system and the use of a rubber valve ball with moderate elasticity, it can effectively handle slurry with high concentrations or containing solid particles.

ZHJ-167/1.8 Series Mine Fire-Prevention and Extinguishment Grouting Unit
The mine-use fire-prevention and extinguishing grouting device is a simple, practical, and reliable colloidal fire-suppression system developed based on extensive field experience in coal-mine fire prevention and control, as well as consideration of the economic and operational conditions specific to coal mines. It can be integrated with surface-based fire-suppression systems to inject coagulants or cementing agents and other fire-extinguishing materials into the grouting pipeline near the grouting location underground. Alternatively, it can be used independently to inject polymeric colloids into fire zones underground for fire suppression.

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.
