Mine full-tailing paste cemented filling material
The invention belongs to the technical field of mine exploitation filling, and particularly relates to a mine full-tailing paste cemented filling material. The solid ingredient of the mine full-tailing paste cemented filling material is composed of the following components in percentage by weight: 8-10% of Portland cement, 88.5-91% of full tailing and 1-1.5% of composite excitant, totaling 100%. The water content of the filling material is 15-25%. The composite excitant in the mine full-tailing paste cemented filling material is a gypsum-lime mixture, can generate the alkali/sulfate double excitation effects, can excite the latent reactivity of the tailing, and can enhance the strength of the filled body, thereby lowering the doping amount of cement.
