Neutralized slag cement slurry, preparation method and application in mine aquifer reinforcement
The invention relates to the technical field of underground grouting reinforcement, in particular to neutralized slag cement paste, a preparation method and application thereof in mine aquifer reinforcement, and the neutralized slag cement paste is used for recycling neutralized slag formed in the ore body mining process and is applied to mine aquifer reinforcement. The neutralized slag cement slurry comprises neutralized slag slurry and cement, the weight ratio of the cement to the neutralized slag slurry is 1: 1-1: 3, and the cement and the neutralized slag slurry are stirred to prepare slurry with the concentration of 50%. The preparation method of the neutralized slag cement slurry comprises the following steps: (1) recycling neutralized slag slurry generated in an ore dressing process; (2) obtaining the recovered neutralized slag slurry and weighing the neutralized slag slurry; (3) cement is added according to the weight of the neutralization slag slurry, the weight ratio of the added cement to the neutralization slag slurry is 1: 1-1: 3, and the neutralization slag cement slurry with the slurry concentration being 50% is prepared. According to the method, waste discharge is reduced by recycling the neutralized slag slurry, the neutralized slag slurry and the cement are mixed to prepare the neutralized slag cement slurry, and the neutralized slag cement slurry is applied to grouting reinforcement of a mine aquifer, so that the use amount of the cement can be greatly reduced.
中和渣水泥浆、制备方法及在矿井含水层加固中的应用，涉及井下注浆加固技术领域，用于对矿体开采过程中形成的中和渣进行回收，并应用于矿井含水层的加固中。中和渣水泥浆，包括中和渣浆和水泥，所述水泥和中和渣浆的重量比为1：1～1：3并将水泥和中和渣浆搅拌配成浓度为50%的浆液。中和渣水泥浆的制备方法，包括以下步骤：（1）对矿石选矿过程中产生的中和渣浆进行回收；（2）获取回收的中和渣浆并对其进行称重；（3）根据中和渣浆的重量，添加水泥，添加的水泥重量与中和渣浆的重量比为1：1～1：3，制得浆液浓度为50%的中和渣水泥浆。本发明通过对中和渣浆的回收，减少了对废物的排放，且通过将中和渣浆和水泥混合制得中和渣水泥浆，并将中和渣水泥浆应用于矿井含水层的注浆加固，可大大减少水泥的使用量。
