摘　　要：全面分析大冶铁矿全尾砂胶结充填质量的影响因素,详细对比了充填搅拌工艺改变后,胶结充填体抗压强度波动的变化。具体分析了二次搅拌替换普通搅拌对充填质量的改善,在有效提高充填体平均抗压强度的同时,有效解决了充填平均抗压强度波动变化大的问题。The influencing factors of the full tailings cementation filling quality in Daye iron mine is amalyzed in de- tail, and compares the change of cementation filling~ compressive strength in detail after the mixing process changed. A de- tailed analysis of the improvement of filling quality after secondary mixing process replacing ordinary mixing process is made. This improvement can effectivelY improve the average compressive strength of filling body, and also solve the problem of the big fluctuation in average compressive strength.
