Abstract

To address the shortcomings of single use of existing fire prevention materials, a novel composite that combined the characteristics of yellow mud and gel was designed and investigated. The composite grout composed of yellow mud and polymer gel can overcome the limitations of single fire prevention materials in fire preventing and extinguishing, and had excellent fluidity and targeting. In view of initial setting time, viscosity, gelling time, material dosage et al., based on the characteristics of the solid-liquid two-state, using the experiments and linear regression methods, the relationship between the different components and its performance were researched, and best raw material components and ratio were chosen. As effective materials for preventing spontaneous combustion of residual coal in goaf, the composites with a water-to-soil ratio of 4:1, base material (4%), coagulant (5%) and polymer materials (0.75‰) had advantages of good liquidity, complete coverage, short gelling time and non-pollution.
