Cemented filling material containing electric furnace reducing slag and application thereof
The invention relates to a cemented filling material containing electric furnace reducing slag and application thereof. The invention relates to a cemented filling material containing electric furnace reducing slag. The cemented filling material is slurry which is mainly formed by mixing a cementing material, lead-zinc tailings and water, wherein the mass ratio of the cementing material to the lead-zinc tailings is (1: 2)-(1: 12); the cementing material comprises the following raw materials in percentage by weight: 10-60% of electric furnace reducing slag, 20-50% of converter slag, 10-60% of slag and 10-40% of desulfurized gypsum. The early strength can be remarkably improved through the synergistic effect of the electric furnace reducing slag and other raw materials, and meanwhile the high strength is achieved after complete condensation; the material has outstanding advantages when being used for filling a mining area, and the mining progress can be accelerated.
本发明涉及一种含电炉还原渣的胶结充填材料及其应用。一种含电炉还原渣的胶结充填材料，所述胶结充填材料是主要由胶凝材料和铅锌尾砂与水混合后而成的浆料；其中，所述胶凝材料和铅锌尾砂的质量比为1:2‑1:12；所述胶凝材料包括以下原料：以重量百分比计，电炉还原渣10‑60％，转炉渣20‑50％，矿渣10‑60％，脱硫石膏10‑40％。本发明利用电炉还原渣与其他原料的协同作用能够显著提高早期强度，同时完全凝结后也具有较高的强度；当该材料用于矿区填充时具有突出优势，能加快采矿进度。
