Acidic slag-based filling material and preparation method thereof
The invention relates to the technical field of mine filling, in particular to an acidic slag-based filling material and a preparation method thereof. The filling material disclosed by the invention is prepared from the following raw materials in parts by weight: 50-150 parts of acidic slag, 30-40 parts of high-alkalinity powder, 10-20 parts of ultrafine active powder, 1-5 parts of an acid-base regulator, 1-5 parts of a dispersion adsorbent, 2-10 parts of an expansion component, 0.5-1.5 parts of a thickening and water-retaining agent and 0.5-1.5 parts of a retarding and water-reducing agent. The invention also provides the preparation method of the filling material. The acidic slag-based filling material has the characteristics of high stone strength, good fluidity, good water retention, good suspension dispersibility, easy transportation, low cost, environmental protection and energy saving.
本发明涉及矿山充填技术领域，尤其涉及一种酸性矿渣基充填材料及其制备方法。本发明所述的充填材料由下述重量份的原料组成：酸性矿渣50‑150份，高碱度粉料30‑40份，超细活性粉体10‑20份，酸碱调节剂1‑5份，分散吸附剂1‑5份，膨胀组分2‑10份，增稠保水剂0.5‑1.5份，缓凝减水剂0.5‑1.5份。本发明还提供了所述充填材料的制备方法。本发明得到的酸性矿渣基充填材料具有结石体强度高、流动性好、保水性好、悬浮分散性好、易输送、成本低、环保节能的特点。
