Abstract
The invention discloses a phosphorous slag composite material for mine filling and a preparation method of the phosphorous slag composite material for mine filling. The material is made of phosphorous slag powder, citric acid or triacetic acid, carbonate, fluosilicate, ground calcium carbonate and cement clinker as raw materials by weight ratio orderly as follows: (20-80): (0.1-3): (0.1-5.5): (0.5-9.5): (0.2-8): (2-40). The preparation method comprises the following steps: first, weighing citric acid or triacetic acid, carbonate, fluosilicate and ground calcium carbonate in proportion, and mixing the same uniformly to obtain a material A; then weighing the material A and phosphorous slag powder in proportion and mixing the same uniformly to obtain a material B; finally, weighing the material B and cement clinker in proportion and mixing the same uniformly to obtain the phosphorous slag composite material. The phosphorous slag composite material for mine filling disclosed by the invention has the following advantages: (1) the material can replace cement so as to reduce the cost of filler; (2) dosage of phosphogypsum is greatly improved so as to relieve the environmental protection pressure of phosphorous chemical enterprises; and (3) the early stage strength of filler is increased. The phosphorous slag composite material for mine filling is appropriate for enterprises with phosphate mines and those for production of phosphoric fertilizer.
Description
Technical field
The present invention relates to the charges that the exploiting field, down-hole charges into, in particular to being used for phosphorus slag matrix material of filling in mine and preparation method thereof.
Background technology
The one Chinese patent application part discloses the method that a kind of phosphogypsum is used for the mine worked-out section consolidated fill 200710193247.X number; Be with cement: shrend iron (steel) slag: phosphogypsum: lime=0.8～1.2: 1.2～0.8: 10～14: 0.4～0.8, making up water and being mixed into weight concentration is 55%～65% filling slurry; Filling method and pulping process thereof after the phosphogypsum gluing are disclosed for Chinese patent ZL200710077624.3 number; Be to be gelling material with cement and flyash; With the phosphogypsum is the technology that main stuffing is carried out filling in mine; The amount ratio of its cement, flyash, phosphogypsum is at 1: 1: 4～6,14 days intensity, 2～3MPa only.The deficiency that above patented technology exists shows that mainly the intensity in early stage of casting resin is not high, and there is certain influence in the mine downhole production.
Summary of the invention
The object of the present invention is to provide a kind of phosphorus slag matrix material that is used for filling in mine, it can place of cement, thereby reduces the cost of stopping composition, consumes phosphogypsum more, creates economic benefit, is beneficial to environment protection.
Another purpose of the present invention is to provide the preparation method of above-mentioned phosphorus slag matrix material, to improve the early strength of obturator, races against time for the mine downhole production, enhances productivity.
The novel phosphorus slag matrix material that is used for filling in mine that the contriver provides is by phosphorus slag powder
,Hydrocerol A or nitrilotriacetic
,Carbonate
,Silicofluoride
,Water-ground limestone
,Cement clinker is processed as raw material, and the weight ratio of above-mentioned each raw material is followed successively by: (20～80)
:(0.1～3)
:(0.1～5.5)
:(0.5～9.5)
:(0.2～8)
:(2～40).
In the above-mentioned matrix material, said phosphorus slag powder is the Water Quenching Slag that yellow phosphorus electric furnace is discharged aborning, and its fineness is that 200 mesh sieve surpluses are less than 10%; Phosphorus slag powder can be used industrial residue replacements such as shrend ground granulated blast furnace slag.
In the above-mentioned matrix material, said Hydrocerol A or nitrilotriacetic are anhydrous compound.
In the above-mentioned matrix material, the muriate that contains in the said carbonate≤0.9%.
In the above-mentioned matrix material, the fineness of said silicofluoride is that 200 mesh sieve surpluses are less than 5%.
In the above-mentioned matrix material, the fineness of said water-ground limestone is that 200 mesh sieve surpluses are less than 15%.
In the above-mentioned matrix material, the CaO.SiO in the said cement clinker
2.Al
