Coal spontaneous combustion is one of disasters threatening the safety production of coal mines, and the main reason is that coal and oxygen in air generate oxidation-reduction reaction and generate a large amount of heat, and if the heat generated by the oxidation-reduction reaction cannot be effectively dissipated, the heat is continuously accumulated, so that the temperature of coal is increased until spontaneous combustion occurs. The spontaneous combustion of coal can cause gas and coal dust explosion sometimes, and seriously threatens the life and property safety of people, so the treatment of the spontaneous combustion of the coal in the mine is very important.
The technology for preventing coal spontaneous combustion by using the inhibition foam material is characterized in that the fluidity and the accumulation of foam are utilized, the inhibition agent can be conveyed to a region to be treated, and the foam containing the inhibition agent wraps the coal body and the crack surface on the surface of the coal body to play the roles of moisture retention, heat absorption and oxygen isolation, so that the oxidation speed of the coal belt at low temperature is reduced, and the natural ignition period of the coal is prolonged. Compared with the prior fire prevention and extinguishing measures such as grouting, glue injection and inerting injection, the inhibition foam fire prevention and extinguishing technology has the advantages that potential safety hazards such as slurry collapse and slurry leakage are avoided, toxic and odorous gases such as ammonia gas are not generated, the process is simple, the inhibition agent can be uniformly covered on the surface of a coal body due to good foam fluidity, and the effect of preventing and controlling spontaneous combustion of the coal is more remarkable.
