The mesh gel foam mud is sprayed to a burning coal layer by an inorganic fiber spray coating machine, thus facilitating generating an integral mesh gel foam mud film in a fire prevention and extinguishing process. The film can always cover and adhere to an ore bed surface to rapidly isolate the burning coal layer from air, prevent coal mine from keeping burning and avoid reburning of the coal layer, thus reaching the purposes of flame retardance and fire prevention and extinguishing. The basalt mesh gel foam mud fire prevention and extinguishing agent is suitable for fire prevention and extinguishing of coal mines, mine operation areas and forests.
