Grouting reinforcement material and preparation method and application thereof
The invention discloses a grouting reinforcement material and a preparation method and application thereof, and the grouting reinforcement material comprises the following raw materials: a component material A and a component material B, the component A material is prepared from the following components in parts by weight: 90 to 96 parts of mineral powder, 4 to 10 parts of gypsum, 0.04 to 1.0 part of a component A water reducing agent, 0.08 to 0.25 part of a component A stabilizer and 40 to 50 parts of water; the material of the component B is prepared from the following components in parts by weight: 15 to 30 parts of sodium metasilicate, 46 to 60 parts of fly ash, 15 to 35 parts of quartz powder, 0.05 to 0.12 part of a water reducing agent of the component B, 0.08 to 0.18 part of a stabilizer of the component B and 40 to 50 parts of water; the grouting reinforcement material disclosed by the invention is rapid in setting and hardening, can rapidly reinforce broken coal and rock masses in an underground coal mine, is low in reaction temperature, and avoids spontaneous combustion of underground coal or gas explosion.
本发明公开了一种注浆加固材料及其制备方法和应用，所述注浆加固材料的原料，包括A组分材料和B组分材料；按重量份数计，所述A组分材料的组分包括：矿粉90份‑96份、石膏4份‑10份、A组分减水剂0.04份‑1.0份、A组分稳定剂0.08份‑0.25份及水40份‑50份；按重量份数计，所述B组分材料的组分包括：偏硅酸钠15份‑30份、粉煤灰46份‑60份、石英粉15份‑35份、B组分减水剂0.05份‑0.12份、B组分稳定剂0.08份‑0.18份及水40份‑50份；本发明中所述注浆加固材料的凝结硬化快，能够快速的对煤矿井下的破碎煤岩体实现加固，且反应温度低，避免引起井下煤炭自燃或瓦斯爆炸。
