摘要
基于我国"三下压煤"现状,研究了以水泥为胶结料,原煤和粉煤灰为粗细骨料的充填材料。通过正交试验的方法,定量确定了水泥、粉煤灰和原煤在不同配比和在不同膏体浓度下对膏体材料各项性能指标的影响程度,以及指标随各因素变化趋势。
Based on the situation of coal mining under buildings, water bodies arid railways, the filing material of cement as cementing material, and raw coal,fly ash respectively as coarse aggregate and fine aggregate is researched. By orthogonal experiment, different proportions of cement, fly ash and raw coal, and paste concentration are quantitatively determined to detect the sensitive degree of index and observe the index change-trend with factors.
