Wet-grinding tailing-based mine filling cementing material and preparation method and application thereof
The invention relates to a wet-grinding tailing-based mine filling cementing material and a preparation method and application thereof. The wet-grinding tailing-based mine filling cementing material is prepared from the following raw materials in parts by weight: 20-30 parts of tailings, 20-30 parts of water-quenched slag, 40-90 parts of water, and 1.6-4.8 parts of a powder sodium excitant. Compared with the prior art, the wet-grinding tailing-based mine filling cementing material provided by the invention adopts specific content components, can realize better interaction, can replace cement as the mine filling cementing material, is low in cost and small in pollution, remarkably improves the utilization rate of mine tailings, solves the problem of accumulation of a large amount of mine tailings, and is suitable for the concept of green sustainable development. Filler slurry further obtained by adopting the wet-grinding tailing-based mine filling cementing material provided by the invention is good in fluidity and excellent in mechanical property.
一种湿磨尾砂基矿山充填胶凝材料及其制备方法和应用，所述湿磨尾砂基矿山充填胶凝材料由包括以下组分的原料制备而成：尾砂20重量份~30重量份；水淬渣20重量份~30重量份；水40重量份~90重量份；粉剂钠系激发剂1.6重量份~4.8重量份。与现有技术相比，本发明提供的湿磨尾砂基矿山充填胶凝材料采用特定含量组分，能够实现较好的相互作用，能够代替水泥作为矿山充填胶凝材料，并且成本低、污染小，同时显著提高了矿山尾砂的利用率，解决矿山尾矿大量堆积的问题，符合绿色可持续发展的理念；采用本发明提供的湿磨尾砂基矿山充填胶凝材料进一步得到的填充体浆料流动度好且力学性能优异。
