Abstract: The present disclosure provides a fire-prevention and extinguishing material for plugging an air leakage in an underground barrier pillar of a coal mine and a use method thereof. The fire-prevention and extinguishing material for plugging the air leakage includes an upper fabric layer, an intermediate layer, and a lower fabric layer. A plurality of fiber filaments are evenly distributed in the intermediate layer such that the intermediate layer has a flexible deformability. The intermediate layer is filled with a cement powder. The upper fabric layer is made of a flame-retardant flexible material. The upper fabric layer is configured to deform under a pressure to block off oxygen and plug the air leakage in the underground barrier pillar. The lower fabric layer is made of a water-soluble material.

Abstract: Disclosed are a train compartment air adjustment and control method and apparatus, and a storage medium and a program product. A ventilation system is adjusted according to microbial diffusion situations among various test points, so as to reduce a microbial pollution index of an area where passengers are located. The method has a guide effect on railway train air quality adjustment and control. By means of the present invention, a mapping relationship between microbial pollution and the concentration of atmospheric pollutants is studied, the problem of the real-time performance of microbial detection can be effectively solved, and the real-time adjustment and control of microbial pollution in a train compartment are guaranteed.
