Full-industrial solid waste filling material for large-cavity goaf and preparation method of full-industrial solid waste filling material
The invention discloses a full-industrial solid waste filling material for a large-cavity goaf and a preparation method of the full-industrial solid waste filling material. The filling material comprises fly ash, coal gangue, red mud, water and a composite alkali activator, and the doping amount of each component is as follows: 224-252kg/m < 3 > of fly ash, 1294.4-1456.2 kg/m < 3 > of coal gangue, 160-180kg/m < 3 > of red mud, 307.2-345.6 kg/m < 3 > of water and 40-45kg/m < 3 > of a composite alkali activator. The filling material based on the industrial solid waste such as the coal gangue is good in stability and high in setting rate, can digest a large amount of the industrial solid waste such as the coal gangue, the coal ash and the red mud, greatly reduces the construction cost, and is suitable for treatment and backfilling of a large-cavity goaf.
本发明公开了一种一种面向大空洞采空区的全工业固废类充填材料及其制备方法。所述的充填材料包括粉煤灰、煤矸石、赤泥、水、复合碱激发剂，各组分掺量为：粉煤灰224‑252kg/m3、煤矸石1294.4‑1456.2kg/m3、赤泥160‑180kg/m3、水307.2‑345.6kg/m3、复合碱激发剂40‑45kg/m3。本发明制备的基于煤矸石等工业固废的充填材料，稳定性好，结实率高，可以大量消化煤矸石、粉煤灰、赤泥等工业固体废弃物，工程造价大幅降低，适用于大空洞采空区的处治回填。
