In order to reduce the amount of high energy consumption materials such as cement in filling, save resources, and fully recycle industrial waste. In this paper, Changxing coal mine as the research background, through data analysis, and through the test configuration based on red mud iron tailings, mixed with desulfurization gypsum, lime, cement, activator of new cementitious materials. And through the test analysis, the best proportion of coagulant admixture is determined as follows: red mud iron tailings dosage 6, cement sand ratio 1:3, mass concentration 68%.
