Abstract

The invention provides a mine filling material and a preparation method thereof. The mine filling material is prepared from, by weight, 90-95 parts of a curing agent, 10-25 parts of sludge, 1-5 partsof construction waste particles, 0.5-2 parts of municipal waste particles, 0.1-0.5 part of a rheology modifier, 0.1-0.5 part of a thickening time control agent and 0.1-0.5 part of a defoaming agent; and the curing agent comprises 25-35 parts of ettringite, 25-35 parts of calcium silicate clinker, 15-25 parts of calcium sulfate, 15-20 parts of quick lime and 0.5-1 part of aluminum powder. The minefilling material can be stably conveyed into a filling mine for a long distance, the safety of a filling system can be guaranteed in the conveying process, condensation and segregation are avoided inthe conveying process, meanwhile, after a filling slurry is conveyed into a target mine, rapid condensation can be achieved, the strength is guaranteed, ecological environment treatment is achieved, and meanwhile waste materials are comprehensively recycled.

Description

technical field [0001] The invention relates to the technical field of mine filling application, in particular to a mine filling material and a preparation method thereof. Background technique [0002] Mine filling is gradually developed to meet the needs of mining development.
