Coal spontaneous combustion preventing inhibition foam material and preparation method thereof

The invention discloses a coal spontaneous combustion preventing inhibition foam material and a preparation method thereof. The coal spontaneous combustion preventing inhibition foam material belongs to the technical field of coal mine underground coal spontaneous combustion treatment. The coal spontaneous combustion preventing inhibition foam material is characterized by comprising, by weight percentage, 0.5-10% of foaming agent, 0.2-3% of foaming auxiliaries, 0.02-0.5% of thickener, 0.5-5% of inhibitor, 2.5-15% of enhancer and 66.5-96.28% of water. After being foamed, the coal spontaneous combustion preventing inhibition foam material can take foam as the carrier to effectively convey the target inhibitor and enhancer to areas complicated to handle, and generated inhibiting foam achieves multiple oxygen insulating inhibition effects on coal spontaneous combustion and further achieves the aim of preventing coal spontaneous combustion.
