Mobile Fire Prevention and Extinguishing Grouting Device for Mining 200-1.2
The ZHJ series mobile fire prevention and extinguishing grouting device for coal mines can operate at coal mine working faces and goaf areas where there is a risk of coal spontaneous combustion. It serves as a fire prevention and extinguishing device that sprays slurry materials such as mud, fly ash slurry, lime slurry, and chemical gels using water as the conveying medium (or higher viscosity liquids and concentrates containing mechanical impurities and solid particles). It effectively fills areas of spontaneous combustion underground using inorganic mineral materials, absorbing the heat energy from oxidizing coal, preventing coal oxidation, and blocking air leakage channels, among other fire prevention and extinguishing functions.

Mobile Fire Prevention and Extinguishing Grouting Device for Mining
Product Introduction
The ZHJ series mobile fire prevention and extinguishing grouting device for coal mines can be used at coal mine underground working faces and goaf areas where there is a risk of spontaneous coal combustion. It serves as equipment for spraying slurry materials such as water-based slurry, fly ash slurry, lime slurry, and chemical gels (or higher viscosity liquids and concentrates containing mechanical impurities and solid particles) for fire prevention and extinguishing. It effectively fills areas of spontaneous combustion underground using inorganic mineral materials, absorbing the heat from oxidizing coal, preventing coal oxidation, and blocking air leakage channels, among other fire prevention and extinguishing functions.
Product Features and Advantages
Features:
1. Adapted to the underground coal mine environment and fire prevention needs, with rapid mobility. The entire set of equipment is equipped with a mine car chassis, wheels, axle supports, bumpers, etc., all manufactured according to underground coal mine standard rail types and gauges, allowing direct underground operation.
2. The grouting device can refine non-combustible grouting materials and mix them with water in a certain ratio to produce extinguishing agents, which are delivered to the mine fire prevention area through pipelines using static or dynamic pressure to prevent coal oxidation or extinguish burning coal.
3. Liquid tanks operate alternately to ensure continuous pump operation.
4. The entire device includes an automatic stirring and slurry preparation system, pressurized slurry delivery system, pressure and flow regulation system, and electric control system. Once the equipment reaches the work site and power is connected, it can operate immediately.
5. The electric control system (including motors and switches) uses explosion-proof types suitable for 660/1140V dual voltage.
Advantages:1. Mobile on underground rails, convenient for transportation.
2. Two or more types of powdered materials can be mixed.
3. Equipped with a mechanical stirring system, enabling mechanized continuous production; as long as materials are supplied timely, high-quality slurry can be produced.Usage Conditions:
The loess and lime powder used should be screened and filtered, free of particles and impurities.
Product Applications
Mainly used at coal mine underground working faces and mining areas with spontaneous coal combustion risks. It sprays slurry materials such as water-based slurry, fly ash slurry, lime slurry, and chemical coagulation gels (or higher viscosity liquids and concentrates containing organic impurities and solid particles) for fire prevention and extinguishing. It effectively absorbs the heat from oxidizing coal, prevents coal oxidation, and blocks air leakage channels to achieve fire prevention and extinguishing.
