Abstract
The invention discloses a kind of coal gangue slurry liquid, its main component is cement and colliery powder, and unslaked lime and gypsum etc. are used for the water blockoff engineering of damming of mine working as admixture.Have with low cost, utilization of waste material, preparation is simple, calculus rate and calculus intensity height are applicable to characteristics such as multiple grouting for water-blocking engineering.
Description
The present invention relates to compositions field, a kind of specifically coal gangue slurry liquid.
At present, in the grouting for water-blocking engineering in mine working and tunnel, adopt cement or clay cement slurry to carry out more.Carry out grouting for water-blocking cost height with cement, carry out grouting for water-blocking with clay cement slurry, water plugging effect is good, can reduce the part expense, but clay cement slurry calculus rate is low, and calculus intensity is low, can not adapt in the grouting for water-blocking engineering of big crack to use.Therefore, people look forward to having and a kind ofly can reduce cement consumption, and cost is low, calculus intensity height, adapt to multiple water blockoff engineering, the appearance of the novel slurry filling material of particularly big crack grouting for water-blocking engineering.
Purpose of the present invention provides a kind of cost low to society exactly, calculus intensity height, and water plugging effect is good, and can adapt to the coal gangue slurry liquid of multiple water blockoff engineering.
The present invention is achieved in that it mainly contains cement, colliery powder, unslaked lime, gypsum and calcium chloride and constitutes, its main raw material and proportioning are cement 25-35%, colliery powder 55-65%, and admixture and proportioning are unslaked lime 5-15%, gypsum 0.9%, calcium chloride 0.3%.Cement can adopt the ordinary Portland cement of 425-525#, colliery powder adopts silt content few, carbon content 3% with interior clean coal gangue, make colliery powder through fragmentation, grinding, screening, two kinds of size compositions are arranged, a kind of is φ 0.15mm, another kind is φ 0.08mm, the ratio that they account for the colliery powder total amount is respectively 6-10% and 90-94%, and the fragmentation of coal gangue can be used crusher, pulverizer, and also available separating machine carries out.With cement by water cement ratio 0.6-1: 1 is mixed with cement grout, after once stirring, puts into the secondary stirring machine, colliery powder, unslaked lime and gypsum and calcium chloride is mixed in the cement grout in proportion to stir again, is coal gangue slurry liquid.When water cement ratio was 1: 1, the add-on of colliery powder should add in 60% ratio.
Advantage of the present invention is: with low cost, and utilization of waste material, compound method is simple, calculus rate and calculus intensity height, the grouting for water-blocking engineering of suitable multiple degree of splitting.
It below is most preferred embodiment of the present invention
The process for preparation and the method for coal gangue slurry liquid are as follows: the preparation of the first step main raw material, and cement adopts the 425# ordinary Portland cement, and coal-gangue-powder is selected the few and clean coal gangue of silt content for use, and carbon content is controlled in 3%.At first the coal gangue chosen being carried out fragmentation with crusher carries out carrying out after the coarse crushing in small, broken bits earlier, carry out abrasive dust with pulverizer then, square hole sieve with 0.15mm and 0.08mm advances screening at last, again the colliery powder of φ 0.15mm and 0.08mm is got 6% and 94% respectively and mixed the even colliery powder that is, simultaneously, with admixture unslaked lime, gypsum and calcium chloride ready for use.The preparation of the second step coal gangue slurry liquid, get 30% cement by ampoule, be mixed with cement grout at 1: 1 by water cement ratio, after once stirring, put into the secondary stirring machine, get 60% colliery powder again, 10% unslaked lime, 0.9% gypsum and 0.3% calcium chloride are put into the secondary stirring machine and are stirred evenly and be coal gangue slurry liquid.Can be directly used in the grouting for water-blocking engineering, pour into water blockoff if cooperate the two slurries of cement-sodium silicate to use, effect can be better.
Claims (2)
1, a kind of coal gangue slurry liquid of forming by cement, colliery powder, unslaked lime and gypsum calcium chloride, it is characterized in that: cement, colliery powder are as main raw material, unslaked lime, gypsum and calcium chloride are as admixture, the proportioning of main raw material and admixture is cement 25-35%, colliery powder 55-65%, unslaked lime 5-15%, gypsum 0.9%, calcium chloride 0.3%, cement can adopt the 425-525# ordinary Portland cement, and colliery powder is made with the coal gangue that carbon content is lower than 3%, silt content is few and clean.
2, coal gangue slurry liquid according to claim 1 is characterized in that colliery powder is made up of the colliery powder of two kinds of granularities of φ 0.15mm and 0.08mm, and the ratio that accounts for the colliery powder total amount separately is respectively 6～10% and 90～94%.
