Mine pneumatic fire-prevention and extinguishing grouting device
The ZHJQ series mine-use pneumatic grouting and fire-extinguishing device is a new type of grouting equipment. Its two mixing tanks enable the alternating supply of two chemical solutions, with continuously adjustable flow rates and precise mixing ratios. It can be configured to deliver filling and sealing materials—including mine-grade gels, slurries, backfilling and sealing agents, and fire-retardant plugging agents—as well as dust-suppression and inerting materials, which are then pressurized and conveyed through pipelines to the fire-extinguishing site.

Mine pneumatic fire-prevention and extinguishing grouting device
Product Introduction
The ZHJQ series mine-use pneumatic grouting and fire-extinguishing device is a new type of grouting equipment. Its two mixing tanks allow for the alternating supply of two chemical solutions, with continuously adjustable flow rates and precise mixing ratios. It can be configured to deliver filling, sealing, flame-retardant, dust-suppression, and other materials—including mine-use gels, slurries, filling and sealing compounds, and fire-sealing agents—by pressurizing them and输送 them through pipelines to the fire-extinguishing site.
Product Features and Benefits
Features:
1. Powered by the air source in the underground compressed-air pipeline, no power supply required.
2. The working principle of separately conveying two slurries and synthesizing foam at the end, enabling long-distance transportation while minimizing the risk of pipe and equipment blockages.
3. It features multiple functions in one device, small size, and light weight (allowing for manual handling).
Advantages:
1. Uses the air source from the underground compressed-air pipeline as its power source, requiring no external power supply;
2. The working principle of separately conveying two slurries and synthesizing foam at the end, enabling long-distance transportation while minimizing the risk of pipe and equipment blockages.Product Use
The device uses materials, underground water sources, and gas sources to prepare a filling and sealing material at the filling site, which can serve as a temporary measure to prevent coal from oxidizing and spontaneously combusting.
- Inject and fill gaps prone to air leakage;
- Spraying of float coal that is easily oxidized and self-ignites.
- Spraying, injecting gel, inhibitor solution, or dust suppressant.
- Spraying a fire-retardant solution onto residual coal in the old gob area of the coal mining face to prevent spontaneous combustion.
- Spraying a fire-retardant solution onto residual coal in voids caused by roof collapses in roadways.
