Abstract
The invention discloses a mine whole-tailing alkali binding material bond filling material, which is formed by mixing an alkali exciting agent, industrial waste residues containing glass bodies, cement, whole tailings and water, a mass ratio of the alkali exciting agent, the industrial waste residues containing glass bodies, the cement, the whole tailings to water is (10-30): (10-70): (0-20): (880-980): (150-350). According to the invention, the alkali exciting agent enables silicon aluminum in industrial waste residue powder containing glass bodies and natural silicon aluminum mineral powder in the whole tailings to be subjected to depolymerization, migration and repolymerization, so that the filling body strength can be greatly improved, then the mixing amount of the cement is substantially reduced or the requirement of the mine filling material performance can be met without mixing cement, therefore, the cost of the filling material is lowered; and meanwhile, the industrial waste residues containing the glass bodies such as granulated blast furnace slag powder, steel slag powder, copper slag powder, coal ash and the like can be fully utilized, so that the waste materials are changed into things of value, the waste residue pollution is reduced, and the environment protection is facilitated.
Description
Technical field
The present invention relates to a kind of mine full tailings alkali binding material cemented filling material.
Background technology
Mine all-tailing cemented filling method is a kind of novel mining technique, is about to the ore that mining goes out, and the waste material (being full tailings) that process extracts behind the useful metal adds solidifying agent (being cement), refills the method in worked-out section.At present, mine all-tailing cemented filling material is after being mixed in proportion by full tailings, general purpose portland cement, water, to deliver to the underground mining place by pipeline self or force (forcing) pump.At present mine all-tailing cemented filling material will reach transport condition and requirement of strength (28d Kang pressure Du＞=2MPa), too large (the about 200kg of cement mixing content in per 1 cubic metre of compaction material of cement mixing content, be that cement accounts for solid content more than 13%), the compaction material cost is high.
Goal of the invention
The purpose of this invention is to provide the low a kind of mine full tailings alkali binding material cemented filling material of a kind of cost.
For achieving the above object, the technical solution used in the present invention is:
A kind of mine full tailings alkali binding material cemented filling material, by alkali-activator, contain Vitrea industrial residue, cement, full tailings, water mixes, its quality proportioning is: alkali-activator: contain Vitrea industrial residue: cement: full tailings: water=10～30: 10～70: 0～20: 880～980: 150～350.
The mixture that described alkali-activator is comprised of alkali metal hydroxide and its soluble silicate.
Described to contain Vitrea industrial residue be that one or more mix by GBFS, steel-making slag powder, copper ashes powder, flyash contain in the vitreum industrial residue, and fineness is 300～450m
2/ kg.
Described cement be in silicate cement, aluminosulfate cement, the high-alumina cement any one.
Full tailings be in the siliceous full tailings in mine, the full tailings of ferrosilicon matter, the full tailings of aluminium matter or the full tailings of sulphur matter any one.
Among the present invention, cemented filling material by alkali-activator, contain Vitrea industrial residue, cement, full tailings, water mixes, the mixture that alkali-activator is comprised of alkali metal hydroxide and its soluble silicate, alkali-activator can make sial depolymerization, migration, the repolymerization that contains natural silicon aluminium acid salt mineral powder in Vitrea Industry Waste ground-slag and the full tailings, can greatly improve strength of filling mass, thereby make cement mixing content decrease or not water mixing mud can reach the performance requriements of filling in mine material, thereby reduce the compaction material cost; The present invention can take full advantage of GBFS, steel-making slag powder, copper ashes powder, flyash etc. and contain the vitreum industrial residue, turns waste into wealth, and reduces residue contamination, is beneficial to environmental protection.
