Mine filling material
The invention provides a mine filling material which is prepared from the following raw materials in parts by mass: 20-53.5 parts of iron tailings, 0-30 parts of blast furnace pelletized slag, 15-25 parts of slag geopolymeric cement, 4-6 parts of dihydrate gypsum and 0-0.5 part of an early strength agent sodium chloride. The raw materials are mixed, sufficiently stirred, vibrated, cast and maintained. The mine filling material is large in early strength, air shrinkage of the filling material is compensated through minimum inflation of slag, the ground pressure resistance is improved, metallurgy waste materials such as slag, blast furnace slag and iron tailings are efficiently utilized, and the ecology and environment are protected.
