针对现有煤矿防灭火材料封堵强度低、成本高及破坏环境等问题,选取硫铝酸盐超细水泥10%~40%、粉煤灰10%~40%、羧甲基纤维素0.5%~0.9%、氟化钠0.1%~0.6%、三聚氰胺0.2%~0.6%、硫酸铝0.1%~0.4%、十二烷基硫酸钠0.3%~0.6%、十二烷基苯磺酸钠0.4%~0.6%、皂素0.5%~0.8%等成分,制备新型防治煤炭自燃的粉煤灰-水泥泡沫材料,并将其在唐口煤矿某回采工作面进行技术应用。结果表明:新型材料的阻燃技术能有效降低工作面温度上升速率。 Aiming at the problems such as low sealing strength, high cost and environmental damage of the existing coal mine fire control materials, 10% ~ 40% sulphoaluminate fine cement, 10% ~ 40% fly ash, 0.5% carboxymethylcellulose, ~ 0.9%, sodium fluoride 0.1% ~ 0.6%, melamine 0.2% ~ 0.6%, aluminum sulfate 0.1% ~ 0.4%, sodium lauryl sulfate 0.3% ~ 0.6%, sodium dodecyl benzene sulfonate 0.4% ~ 0.6%, saponin 0.5% ~ 0.8% and other ingredients, to prepare a new type of fly ash-cement foam material for prevention and control of spontaneous combustion of coal and to apply the technology to a coal mining face in Tangkou Coal Mine. The results show that the flame retardant technology of new materials can effectively reduce the temperature rise rate of working face.
