Mine fire caused by coal spontaneous combustion is one of the main safety problems in mining. For the purpose of developing a more effective inhibitor to suppress the coal spontaneous combustion, a compound deoxidization gel foam inhibitor was proposed by combining sodium dithionite deoxidizer with gel foam. An experimental platform was self‐built to evaluate the suppression characteristic of deoxidization...
The three‐phase foam consisted of solid, liquid and gas is regarded as a highly effective measure for the underground mine fire prevention. In this study, the three‐phase foam technology is introduced and a visualization platform is established to exhibit the foam flow in a physical goaf. The diffusion rule and extinguishing performance for three‐phase foam are researched. Test results show that the...
