Abstract

The invention discloses a filling gel material for mines. The filling gel material is prepared from the following raw materials: mineral slag, quick lime, desulfurized gypsum, cement clinker and mirabilite. A gel agent meeting the requirement of full tailing filling of the mines is produced from blast furnace slag, so that environmental pollution caused by the ground stacking of the mineral slag is solved; and meanwhile, the gel agent with the mineral slag relatively low in cost as main component is adopted, so that the use of cement in the filling process of the mines is reduced, and the filling cost is lowered.

Description

technical field [0001] The invention relates to a mine filling cementitious material. Background technique [0002] Granulated blast furnace slag, also known as slag, is the main by-product produced in the process of smelting pig iron in iron and steel plants. During the blast furnace smelting process, molten blast furnace slag with silicates and aluminosilicates as the main components is formed, which floats on the surface with a relatively high density. The surface of molten iron is rapidly cooled in water when it is discharged to limit its crystallization and become granular water-quenched blast furnace slag with glass as the main component and hydraulicity. In recent years, with the development of the metallurgical industry, the output of iron and steel has continued to increase, and the discharge of slag from metallurgical enterprises has also continued to increase. Relevant statistics show that iron and steel enterprises discharge nearly 100 million tons of water-quen...
