Study on Physical Properties of Cement Filling Material by Ore Tailing

Authors: Chao Chen, De Qing Gan, Zhi Ling Guo, Ya Bin Zhang

Abstract: According to the occurrence of ore, mining use different cement filling mining, due to different filling body, in a different role in the maintenance of stope stability, so filling body required different strength. By regression analysis of filling body strength with sand ratio, slurry concentration and fine sand content, to get different body strength of different filling mining, and also can be the primary and secondary and the impact degree of various factors which impact the strength of filling body.
