The invention discloses a preparation method of a basalt composite fiber water permeable brick. The method comprises the following steps of: uniformly mixing basalt ore, sepiolite powder and talcum powder, heating an obtained mixture until obtaining a melt, and performing centrifugal spinning to obtain cotton fibers; mixing the cotton fibers, konjac glucomannan and a sodium hydroxide solution, stirring an obtained mixture at 60-70 DEG C for 30-50 minutes, performing filtering and washing, and performing drying at 90-98 DEG C for 1-2 hours to obtain basalt composite fibers; uniformly mixing pre-ground cement clinker, the basalt composite fibers, coal mine waste residues, fly ash, desulfurized gypsum and an additive, and grinding an obtained mixture to obtain a cementing material; uniformlymixing aggregate, the cementing material, water, a water reducing agent and a surfactant, performing molding by using a grinding tool under the molding pressure of 18-20MPa, performing curing at the temperature of 20-25 DEG C for 28-30 days, and keeping the humidity at 80-88% in the curing process, thereby obtaining the basalt composite fiber water permeable brick.
本发明公开了一种玄武岩复合纤维透水砖的制备方法，包括如下步骤：将玄武岩矿石、海泡石粉、滑石粉混合均匀，加热至熔融，离心抽丝得到棉絮状纤维；将棉絮状纤维、魔芋葡甘聚糖、氢氧化钠溶液混合，60‑70℃搅拌30‑50min，过滤，洗涤，90‑98℃干燥1‑2h，得到玄武岩复合纤维；将预磨细水泥熟料、玄武岩复合纤维、煤矿废渣、粉煤灰、脱硫石膏、添加剂混合均匀，研磨得到胶凝材料；将骨料、胶凝材料、水、减水剂、表面活性剂混合均匀，磨具成型，成型压力为18‑20MPa，20‑25℃养护28‑30天，养护过程中保持湿度为80‑88％，得到玄武岩复合纤维透水砖。
