TYKM-SPM-3 Three-Phase Foam Fire Extinguishing Agent for Mining
The mining three-phase foam fire extinguisher system is formed by nitrogen or underground compressed air combined with MT mining three-phase foam fire extinguisher and solid particle foaming. The foam expansion ratio is greater than 30 times. It diffuses in the goaf area and can accumulate upwards, covering floating coal effectively. This overcomes the shortcomings of grouting, which cannot uniformly cover floating coal and is prone to "grout leakage." It isolates oxygen from the coal body, stopping coal oxidation and heat generation reactions. As the foaming process continues, the foam coverage area expands, penetrating coal fissures, enlarging the fire extinguishing zone until the entire fire source is extinguished. At the same time, it covers the floating coal in the fire source area, providing cooling, heat dissipation, and temperature reduction. The foam has a long stabilization time, effectively preventing spontaneous combustion of coal. After the foam breaks, the nitrogen in the foam is released into the goaf, reducing oxygen content and fully exerting the suffocation fire extinguishing effect.

TYKM-SPM-3 Mine Use Three-Phase Foam Fire Extinguishing Agent
Product Introduction
The mine use three-phase foam fire extinguishing agent is a system formed by nitrogen or underground compressed air combined with MT mine use three-phase foam fire extinguishing agent and solid particle foaming. The foam expansion ratio is greater than 30 times. It diffuses in the goaf area and can accumulate upwards, covering floating coal effectively. This overcomes the shortcomings of grouting not uniformly covering floating coal and easy "grout leakage," isolating oxygen from the coal body, stopping coal oxidation and heat generation reactions. As the foaming process continues, the foam coverage area expands, penetrating coal fissures, enlarging the fire extinguishing circle until the entire fire source is extinguished; at the same time, it covers the floating coal in the fire source area, providing cooling, heat dissipation, and temperature reduction. The foam has a long stable foam time, effectively preventing spontaneous combustion of coal; after the foam breaks, the nitrogen in the foam is released into the goaf area, reducing oxygen content and fully exerting the suffocation fire extinguishing effect.
Product Features
It has good diffusion performance in the goaf area. The generated foam can cover high, medium, and low fire sources over a large range and in all directions, maintaining the coal body moist and cooled for a long time; effectively covers and adheres to floating coal fissures, with good sealing of air leakage channels and oxygen isolation performance; it allows slow release of nitrogen in the foam, avoiding the nitrogen loss problem when nitrogen is injected alone, maintaining long-lasting inertness in the fire area, effectively preventing spontaneous combustion of coal.
