Abstract: In order to keep the goaf stable and moisturizing for a long time and prevent spontaneous combustion, it is necessary to fill with glue to seal up leakage, and to prevent fire by oxygen-insulating cooling. In this paper, a new type of composite colloid fire-extinguishing material is presented, which combines organic polymers and inorganic coagulants, and studies the fire extinguishing performance of the new colloidal inhibitor for coal mines by analyzing the water-holding property, thermal stability, plugging property, bonding property, colloid strength and other indicators of the material. The results showed that when sodium alginate was 4.6%, coagulant accelerator was 2.5%, polyacrylamide was 0.4%, and xanthan gum was 1.0%, the water retention and thermal stability of the gel inhibitor were the best, the plugging performance was increased by 52.70%, the bonding performance was increased by 117.62%, and the colloid strength was doubled.
