Aeolian sand filling material for mine filling and preparation method thereof
The invention provides an aeolian sand filling material for mine filling and a preparation method of the aeolian sand filling material. The aeolian sand filling material comprises the following components: 25-60 parts of aeolian sand, 3-20 parts of gangue, 3-25 parts of cement, 10-25 parts of fly ash and 20-30 parts of water. Wherein the gangue is crushed gangue particles, and the particle size of the gangue particles is not larger than 10 mm. And the mass fraction of the slurry of the aeolian sand filling material is 70-80%. The aeolian sand filling material provided by the invention is prepared from the aeolian sand, the gangue, the fly ash, the cement and the water as raw materials, and the performance of the aeolian sand filling material can achieve the effect of a pure cement cementing material; and compared with the existing single aggregate aeolian sand filling, the mine filling material has the advantages of stable slurry structure, small bleeding of the filling material, no need of dehydration underground, good suspension property and high filling material strength. And in the long-distance pipeline conveying process, the slurry flow state stability is high, and pipeline conveying is smooth.
本发明提供的一种用于矿山充填的风积沙充填材料及其制备方法，包括如下组分：风积沙25～60份，矸石3～20份，水泥3～25份，粉煤灰10～25份，水20～30份。其中矸石为破碎后的矸石颗粒，矸石颗粒的粒径不大于10mm。风积沙充填材料的料浆质量分数为70％～80％。本发明提供的风积沙充填材料，采用风积沙、矸石、粉煤灰、水泥和水为原料制备，其性能可以达到纯水泥胶凝材料的效果，而且这种矿山充填材料与目前单一骨料风积沙充填相比其料浆结构稳定、充填材料泌水小、井下不需脱水、悬浮性好、充填材料强度高。长距离管道输送过程中料浆流态稳定性强，管道输送通畅。
