摘要通过均匀设计测试新型复合胶结材料的充填体强度，并应用DPS数据处理和Matlab数学软件共同对强度和配方进行二次多项式非线性回归和约束非线性规划优化。实验结果表明：矿渣需要在碱性环境下加入适量硫酸盐才能激发其活性增加其胶结能力；矿渣含量对新型胶结材料强度起决定性作用，矿渣含量为76%～87%时强度能取得最优值；石灰和石膏复合激发剂对新型复合胶结充填体强度起到催化剂作用，在其含量为13%～24%时充填体强度能明显提高；新型复合胶结充填体强度是水泥充填体强度的6～8倍，具有很大优势；通过软件分别建立3，7和28 d强度与新型复合胶结材料配方的回归公式，并得出3，7和28 d最优新型复合胶结材料配方和最大抗压强度值。

Abstract：This paper makes the new cementing material strength experiment through the uniform design is carried out. This paper applies DPS and Matlab software is applied to strength and formula quadratic multinomial nonlinear regression and optimization. The experiment shows that，in the alkaline environment，sulphate should be added into the slag to arouse its activity to increase its cementation ability. Among the components，slag plays a decisive role in the strength of the cementing material which would have the greatest strength with 76% to 87% slag. At the same time，the compound activator of lime and plaster acts as a catalyst for the strength of the cementing material which would have the greatest strength with 13% to 24% activator. According to the test，the filling strength of new composite material is much higher than that of cement filling，with the number of six to eight times. Using the numerical software，a quadratic polynomial regression formula of 3，7 and 28 days models and strengths was built. In addition，by optimizing the formula，the optimal proportion and the value of greatest compressive strength were acquired.

Key words： mining engineering slag new cementing material composite inspire agent uniform design polynomial regression
