High-expansion foam fire extinguishing agents are widely used in confined spaces such as coal mines, tunnels, aircraft hangars, garages, ships, warehouses, basements, as well as large-area surface oil fires. High-expansion foam fire extinguishing agents are based on high-efficiency foaming agents, with appropriate additions of foam stabilizers, solvents, antifreeze agents, etc. They belong to the general-purpose synthetic foam fire extinguishing agents suitable for both high and medium expansion ratios. The agent is mixed with water at a ratio of 3:97 or 6:94 and can be used with various types of high and medium expansion foam generating equipment. The extinguishing agent should be stored sealed indoors in a cool, dry, ventilated environment with a temperature range of -5~40℃, and has a shelf life of two years.

Coal mine slurry additive is an active material mixed with inorganic materials, possessing strong water retention and adhesion properties. When added to fly ash slurry or yellow mud slurry, it can thicken quickly, overcoming the shortcomings of fly ash slurry or yellow mud slurry being hydrophobic and dehydrating rapidly. This makes the slurry more fluid and suspensive, less likely to clog pipelines, and able to quickly seal and encapsulate the coal body upon reaching the grouting site, achieving oxygen isolation. It can tightly fill the gaps in the coal seam, block air leaks, isolate oxygen, and also provide cooling and heat absorption effects. This solves the common "impact groove" phenomenon in traditional grouting, improves the utilization of solids and water, and addresses the problem of large amounts of water discharge on the working face.
