Method for filling abandoned mine with solid waste slurry and mineralizing and storing CO2
The invention belongs to the technical field of solid waste resource building material utilization in the field of resource environment, and particularly relates to a method for filling a waste mine with solid waste slurry and mineralizing and sealing CO2, which comprises the following steps: S1, pouring and spraying solid waste-based plugging slurry on the bottom and the wall surface of the waste mine, and curing to form a plugging layer; s2, solid-waste-based CO2 foam slurry is injected into the abandoned mine, a porous stone body with pores filled with CO2 is formed after solidification, and the supporting effect on the abandoned mine is achieved; and S3, solid-waste-based micro-expansion slurry is injected into the top of the abandoned mine, a closed protective shell is formed after solidification, and CO2 is prevented from leaking out of the abandoned mine. CO2 can be stably sealed and prevented from being discharged into the atmosphere, meanwhile, the problem of environmental pollution caused by solid waste accumulation is solved, and the problems of collapse of broken surrounding rocks, collapse of mining areas, subsidence of surrounding foundations and the like of abandoned mines are prevented.
本发明属于资源环境领域固废资源化建材利用技术领域，具体涉及一种固废浆料充填废弃矿井且矿化封存CO2的方法，包括以下步骤：S1、在废弃矿井底部及壁面浇注喷涂固废基封堵浆料，固化后形成封堵层；S2、向废弃矿井中注入固废基CO2泡沫浆料，固化后形成孔隙内充满CO2的多孔结石体，对废弃矿井起到支撑作用；S3、在废弃矿井顶部注入固废基微膨胀浆料，固化后形成封闭保护壳，防止CO2从废弃矿井中泄露出来。即可以将CO2稳定封存使其不排放到大气中的同时，解决固废堆积污染环境的问题，防止废弃矿井出现破碎围岩塌方、矿区坍塌及周边地基下陷等问题的发生。
