The invention discloses a novel magnesium-coal cinder-based paving and mining filling material and a preparation method thereof. The material comprises the following raw materials in percentage by weight: 15-50% of a magnesium-coal cinder-based cementing material, 50-85% of aggregate and 0-5% of an additive, the magnesium-coal cinder-based cementing material is a cementing material formed by adding one or two of fly ash and coal gasification slag into magnesium slag serving as a basic raw material; the aggregate comprises one or a combination of more of construction waste, coal gangue, aeolian sand, slag and desulfurized gypsum; the additive comprises one or a combination of more of a retarder, a water reducing agent, an early strength agent and a drag reducer. The invention provides a new utilization way for solid waste treatment in the coal chemical industry and the magnesium smelting industry, and realizes solid waste recycling.
本发明公开了一种镁‑煤渣基新型铺路与矿用充填材料及其制备方法，其材料包括以下重量百分含量的原料：镁‑煤渣基胶凝材料15％～50％、骨料50％～85％、添加剂0％～5％；所述镁‑煤渣基胶凝材料为由镁渣为基础原料，添加粉煤灰、煤气化渣中的一种或两种组成的胶凝材料；所述骨料包括建筑垃圾、煤矸石、风积沙、炉渣和脱硫石膏中的一种或多种的组合；所述添加剂包括缓凝剂、减水剂、早强剂和减阻剂中的一种或多种的组合。本发明为煤化工和炼镁两大支柱行业的固废处置提供了一个新的利用途径，实现了固废再生利用。
