Mine fireproof grouting material prepared from coal gasification ash
The invention discloses a mine fireproof grouting material prepared from coal gasification ash, which comprises the following components by weight: 100 parts of a cementing material; 0 to 200 parts of filler; 0.1 to 3.0 parts of an additive; 40 to 150 parts of water; wherein the cementing material is pulverized coal gasification fly ash; the filler is coal gasification coarse slag and/or coal gasification fine slag; the additive is one or more of a water reducing agent, a retarder, an exciting agent and a thixotropic agent. The coal gasification ash is adopted as a main raw material to prepare the mine fireproof grouting material, the problem of solid waste treatment of the coal gasification ash can be solved, the problem of underground fireproof grouting can also be solved, and meanwhile, the prepared fireproof grouting material is very low in cost and has certain compressive strength; and multiple effects of fireproof grouting, goaf backfilling, goaf bed rock reinforcement, goaf collapse prevention and the like can be realized.
本发明公开了一种利用煤气化灰渣配制的矿井防火注浆材料，按重量计，其包含以下组分：胶凝材料：100份；填料：0‑200份；添加剂：0.1‑3.0份；水：40‑150份；其中，所述胶凝材料为粉煤气化飞灰；所述填料为煤气化粗渣和/或煤气化细渣；所述添加剂为减水剂、缓凝剂、激发剂和触变剂中的一种或多种。采用煤气化灰渣为主要原材料制备矿井防火注浆材料，既可以解决煤气化灰渣的固废处理问题，又可以解决矿井下的防火注浆问题，同时所制备的防火注浆材料的成本很低，还具有一定的抗压强度，可以实现防火注浆、采空区回填、加固采空区的基岩、防止采空区塌陷等多重作用。
