Coal gangue slurry filling material as well as proportion optimization method and application thereof
The invention provides a coal gangue slurry filling material as well as a proportioning optimization method and application thereof. The coal gangue slurry filling material comprises the following components in percentage by mass: 25-40% of water and 60-75% of a solid component, the solid component comprises the following components in percentage by mass: 15 to 40 percent of coal gangue with the particle size of 4.75 to 1.18 mm, 20 to 50 percent of coal gangue with the particle size of 1.18 to 0.425 mm, 5 to 15 percent of coal gangue with the particle size of 0.425 to 0.075 mm and 10 to 25 percent of coal gangue with the particle size of less than 0.075 mm. According to the coal gangue slurry filling material, reasonable coal gangue grading setting and liquid-solid ratio are adopted, the fluidity of the material can be improved, and long-distance conveying is facilitated.
本申请提出一种煤矸石浆体充填材料及其配比的优化方法和应用，其中煤矸石浆体充填材料包括以下质量百分数的各组分：水25‑40％，固体组分60‑75％；所述固体组分包括以下质量百分数的各组分：粒径4.75‑1.18mm的煤矸石15‑40％，粒径1.18‑0.425mm的煤矸石20‑50％，粒径0.425‑0.075mm的煤矸石5‑15％，粒径小于0.075mm的煤矸石10‑25％。本申请的煤矸石浆体充填材料，采用合理的煤矸石级配设置和液固比，可提高材料的流动性，便于长距离输送。
