Preparation and Inhibition Characteristic of Multi-Phase Foamed Gel for Preventing Spontaneous Combustion of Coal

Abstract:

In order to prevent the spontaneous combustion of coal efficaciously, a kind of new compound material of multi-phase foamed gel, which is based on three-phase foam, composed of foaming agent, thickener, fly ash and nitrogen and formed by physical and mechanical stirring, is proposed. It makes use of the all-around capability of gel and three-phase foam to prevent mine fire. The effects of the mass fraction of foaming agent and slurry, the quantitative ratio of polymers and concentration on foam properties had been carried out. The results show that the properties of multi-phase foamed gel are the best when the mass fraction of foaming agent, polymers and slurry were 4‰, 6‰(the quantitative ratio was 1:1) and 16.66%(water cement ratio was 5:1). In addition, the inhibition characteristic of multi-phase foamed gel was studied experimentally and theoretically.
