Phosphogypsum filling material for mine filling and preparation method thereof
The invention relates to the technical field of mine filling materials, and particularly discloses an ardealite filling material for mine filling and a preparation method of the ardealite filling material. The formula comprises the following components in percentage by mass: 9-14% of novel mortar, 4-6% of anhydrite novel mortar, 75-80% of phosphogypsum, 3-5% of fluorosilicon slag and 1-2% of lime. The novel mortar is composite yellow phosphorus slag gelling powder, and during preparation, lime and fluorosilicone slag are firstly mixed and then mixed with mortar, so that the technical problems that in the prior art, the content of phosphogypsum serving as mine hole backfill mortar is too low, and consumption of the phosphogypsum is insufficient are solved.
本申请涉及矿山填充材料技术领域,具体公开了一种矿山填充用磷石膏充填材料及其制备方法。其配方按以下质量百分比组成:新型砂浆9‑14%,无水石膏新型砂浆4‑6%,磷石膏75‑80%,氟硅渣3‑5%,石灰1‑2%;所述新型砂浆为复合黄磷渣胶凝粉,且在制备时先将石灰与氟硅渣进行混合后,再与砂浆混合的方式,解决了现有技术中磷石膏作为矿山矿洞回填砂浆中的含量太低,其对磷石膏的消耗不足的技术问题。
