【摘要】：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。
[Abstract]:Aiming at the problems of low blocking strength, high cost and environmental damage of the existing coal mine fire prevention and extinguishing materials, Select thioaluminate superfine cement 1010: 40, fly ash 1040, carboxymethyl cellulose 0.5 including 0.9, sodium fluoride 0.1 and 0.60, melamine 0.2um, aluminum sulfate 0.40, aluminum sulfate 0.30.64, sodium dodecyl sulfate 0.30.60, sodium dodecyl benzene sulfonate 0.40.6and sodium dodecyl benzenesulfonate 0.40.6.The saponin 0.50.80%, etc. A new type of fly ash-cement foam material for preventing coal spontaneous combustion was prepared and applied in a mining face of Tangkou Coal Mine. The results show that the flame retardant technology of new material can effectively reduce the rising rate of working face temperature.
