Method for preparing mine filling material from ardealite modified red mud
The invention belongs to the technical field of preparation of mine filling materials, and particularly relates to a method for preparing a mine filling material by using ardealite modified red mud, which comprises the following steps: 1) mixing ardealite and red mud, and sequentially drying and grinding to prepare a mixture A of less than or equal to 200 meshes; 2) mixing methylnaphthalene sulfonic acid, formaldehyde and methyl cellulose to prepare a curing agent B; and (3) mixing and stirring the mixture A with the particle size of less than or equal to 200 meshes obtained in the step (1) and the curing agent B obtained in the step (2) to obtain the mine filling material. The method has the advantages of being low in cost, high in product quality, convenient to operate, short in manufacturing time and the like, and the prepared mine filling material has the advantages of being high in strength, not prone to cracking, firm in surface, good in impermeability and freezing resistance and the like.
本发明属于矿山充填材料制备技术领域，具体涉及一种用磷石膏改性赤泥制备矿山充填材料的方法，包括如下步骤：1)将磷石膏、赤泥混合后，依次经烘干、粉磨，制成≤200目的混合料A；2)将甲基萘磺酸、甲醛、甲基纤维素混合，制成固化剂B；3)将步骤1)所得的≤200目的混合料A和步骤2)所得的固化剂B混合搅拌，即得矿山充填材料。本方法具有低成本、产品质量高、操作便捷、制作时间短等优势，制得的矿山充填材料具有强度高、不易开裂、表面坚实、抗渗度和抗冻性较好等优势。
