Fly ash-based guniting material for supporting underground coal mine roadway and preparation method of fly ash-based guniting material
The invention discloses a fly ash-based guniting material for supporting an underground coal mine roadway and a preparation method of the fly ash-based guniting material. The preparation method comprises the steps: mixing fly ash, cement and desulfurized gypsum, and fully stirring to obtain an aggregate mixture; mixing the metakaolin and the mixed additive, and fully stirring to obtain a dry material additive mixture; mixing the aggregate mixture with water, and fully stirring; adding the dry material additive mixture into the mixed slurry, and fully stirring; and finally, adding calcium carbide, and fully stirring to obtain the fly ash-based guniting material. According to the invention, the resource utilization of the solid waste industrial waste residue fly ash generated by coal burning in a thermal power plant is realized, the solid waste environmental problem brought by a coal mine power plant is effectively solved, the preparation method is simple, the raw materials are easy to obtain, the cost is low, and the industrial application advantage is great.
本发明公开了一种用于支护煤矿井下巷道的粉煤灰基喷浆材料及其制备方法，将粉煤灰、水泥、脱硫石膏混合，充分搅拌得到骨料混合物；将偏高岭土、混合外加剂混合，充分搅拌制得干料添加剂混合物；将骨料混合物与水混合，充分搅拌；将干料添加剂混合物加入上述混合浆体中，并充分搅拌；最后加入碳化钙，并充分搅拌，制得粉煤灰基喷浆材料。本发明实现了火力发电厂燃煤产生固体废弃物工业废渣粉煤灰的资源化利用，有效解决了煤矿电厂所带来的固废环境问题，制备方法简单，原料易得且成本低廉，工业性应用优势大。
