To overcome the shortcomings of traditional yellow mud grouting or fly ash grouting, such as easy loss along gullies and inability to spread to higher positions, Yikete Mud Inhibiting Foam uses specialized equipment to convert yellow mud or fly ash into mud foam. The resulting mud inhibiting foam can spread, accumulate, and cover in the goaf with the foam as a carrier, bringing more water and yellow mud into the high, medium, and low positions of the treatment space. This technology integrates four prevention and control methods—mud, nitrogen, water, and inhibitor—utilizing the covering property of yellow mud, the suffocating property of nitrogen, the cooling property of water, and the inhibiting property of the inhibitor for joint treatment, greatly improving the effectiveness of fire prevention and extinguishing.

When the coal-oxygen inhibitor is mixed with water and sprayed onto the surface of coal, it forms a polymer protective film on the coal surface. This protective film has multiple effects: it can not only block the contact between coal and oxygen, inhibit coal spontaneous combustion, and extend the coal storage period, but also effectively suppress the flying of coal dust, avoiding environmental pollution and weight loss caused by wind, rain and erosion.

JTF-I uses microcapsule technology to overcome drawbacks of traditional mine fire control methods. Its gelling material is activated after foaming to achieve first foaming then gelling. This technology integrates the strengths of grouting, inert gas, gel, inhibitors and foam systems while avoiding their weaknesses.
