Novel grouting slurry for mining regenerated roof and preparation method of novel grouting slurry
The invention discloses novel grouting slurry for a mining regenerated roof and a preparation method of the novel grouting slurry, and relates to the technical field of reinforcing and reinforcing grouting slurry. The preparation method comprises the following steps: mixing a sodium silicate solution and calcium chloride, uniformly stirring to obtain an additive, mixing clay and water, uniformly stirring to obtain yellow mud after the slurry sinks and floats, adding ordinary Portland cement, quick lime, the additive and hydroxypropyl methyl cellulose into the yellow mud, and uniformly stirring to obtain the novel grouting slurry for the mine regenerated roof. According to the invention, waste clay in a construction site is used as a main raw material, the use amount of ordinary Portland cement is reduced, the cost is reduced, the resource recycling is realized, hydroxypropyl methyl cellulose has a certain water-retaining property, the viscosity of grouting slurry can be increased, fine particles in original slurry such as clay can be effectively bonded, and the grouting efficiency is improved. And the consolidation strength of a hardened solid body of the grouting slurry can be improved.
本发明公开了一种矿用再生顶板新型灌浆浆液及其制备方法，涉及补强加固灌浆浆液技术领域。将硅酸钠溶液和氯化钙混合后，搅拌均匀得到外加剂，将粘土和水混合后搅拌至均匀，浆液沉浮后得到黄泥浆，将普通硅酸盐水泥、生石灰、外加剂、羟丙基甲基纤维素加入黄泥浆中，搅拌至均匀，得到矿用再生顶板新型灌浆浆液。本发明以建筑工地中的废弃粘土为主要原料，降低普通硅酸盐水泥用量，在降低成本的同时实现了资源的重复利用，羟丙基甲基纤维素具有一定保水性，其可增大灌浆浆液的黏度，能有效地将粘土等原浆液中的细小颗粒粘结起来，有利于提高灌浆浆液硬化结实体的固结强度。
