Abstract

The invention discloses a tailing solidification filling method, a filling material, a cementing agent and a preparation method and a preparation system of the cementing agent, and belongs to the technical field of mining engineering, building materials and solid waste resource utilization. The tailing curing cementing agent is prepared by mixing the following main raw materials in percentage by weight on a dry basis: 50 to 70 percent of silicon-aluminum slag, 10 to 20 percent of alkaline slag, 10 to 30 percent of industrial byproduct gypsum slag and 5 to 10 percent of powdery alkaline exciting agent, and the silicon-aluminum slag slurry, the alkaline slag-industrial byproduct gypsum slag composite slurry and the alkaline exciting agent powder are used as main raw materials. The cementing agent is used for mine filling and curing, the phenomenon that particles are agglomerated and difficult to disperse when dry slag powder is used as a raw material can be effectively overcome, the compactness of an obtained filling body is improved, and meanwhile, compared with an existing cementing agent material, the cementing agent can also be used for cementing superfine particles, and the strength of the cementing body is improved.

Description

technical field [0001] The invention belongs to the technical field of mining engineering, building materials and solid waste resource utilization, and particularly relates to a tailings solidification filling method, filling material, cementing agent and a preparation system and preparation method thereof. Background technique [0002] The filling mining method has the advantages of small loss rate, low dilution rate and high safety, and it is also a mining method that can effectively control the mine ground pressure activities. With the increasing development of backfill mining technology, especially cemented backfill mining technology, many complex technical problems of mines have been well resolved. It has played a huge role in reducing the dilution rate and loss rate, preventing internal fires, slowing down the occurrence of rock bursts, and effectively controlling ground pressure activities. [0003] The filling materials used in the backfill mining method are mainly ...
