There is a certain amount of sulfide is contained in the tailings of nonferrous metal deposits,if the tailings is takens as cemented filling material,the sulfide contained in the tailings will affect the strength of the filling body to some extent. The strength of the filling body with different sulfide contents of Dabaozhuang iron mine is analyzed,the strength evolution regularity is discussed,the microstructure of the filling test blocks is observed by electron microscopy test,besides that,the change mechanism of reaction process of sulfide in filling body is analyzed in detail,to provide some reference for the further optimization of the ratio of filling material and improvement the strength of filling body.
