中文摘要：
利用高炉炉渣研制了一种新型全尾砂充填胶凝材料。该新型胶凝材料由矿渣、石灰、石膏和水泥组成,并且加入少量外加剂。采用正交试验,对新型胶凝材料进行影响因素研究,然后通过DPS数据处理软件建立强度与配方的回归公式,最后确定最优配方。试验表明,采用最优配方的新型胶凝材料,全尾砂充填体强度是32.5#水泥全尾砂充填体强度的3倍,同时新型胶凝材料成本与水泥成本相当或略高,由此可以降低全尾砂充填采矿成本达40%～50%。开发的新型胶凝材料已经在石人沟铁矿现场试验和应用,从而进一步验证了该胶凝材料的可行性与可靠性,为提高石人沟铁矿的充填采矿经济效益奠定了基础。
英文摘要：
A new type cementing material is introduced. It is composed by slag, lime, gypsum and cement, also some additives were added, and the optimal ratio based on the limited test basis. Orthogonal design and test data were used to analyze the influence factors the new type cementing material. Then regression equation between strength and the new type cementing material based on the DPS software was established. At last, the optimal formulation was determined. Results show that the new cementing material strength is 3 times of the 32.5# cement, and its cost is the same as cement materials. So the cost of the filling can decrease as much as 40% - 50%. The new type cementing material has already tested and used in Shirengou iron mine. It indicates the feasibility and reliability of this new type cementing material. It plays a good foundation for improving the economic benefits of Shirengou mine.
