Description
Technical field
The invention belongs to coal mine filling production technique fields, prepare coal mine lotion more particularly to a kind of utilization scrap glass and fill
The method of filling chock material.
Background technique
China is main using coal as one of country of non-renewable energy, the basic energy of coal conduct few in number in the world
Very important effect is played to the national economic development and progress of human society.But coal mining is caused by ecological environment simultaneously
Harm is also growing day by day, and main includes breaking for surface subsidence caused by mining, waste-water from coal mine, gangue and mining area ecological environment
Bad, wherein influence of the surface subsidence to environment is particularly acute.Surface subsidence is primarily due to coal mine gob not by closing
Caused by the improvement of reason.Cut-and-fill Mining Technology be using with some strength and cheap material filling goaf, both can be with
Surface subsidence caused by control is mined, and energy sufficiently back production coal resources, realize resource and environment, safety, Development of Economy
Target.
So-called paste body filling is exactly that the gangue of coal tailing hillock, inferior soil and the tailing of power plant flyash etc. is solid
The paste slurry that body waste is processed on ground is pumped using high density solid filling and is arrived coal mine filling ointment pumping by pipeline
Underground goaf prevents the mining methods of subsidence to support overlying rock.It mainly by mining overburden control theory,
Filling system and filler three parts composition, wherein filler is the basis of paste body filling.With filling mining promote with
Using filling available raw material such as gangue, tailings etc. and gradually decrease, filling cost also gradually increases therewith, paste body filling
The problem of the material deficiency faced becomes increasingly conspicuous.Find filler that is at low cost, meeting fill paste conveying and intensity requirement
It is filling mining urgent problem.
With the development of economy with the raising of living standards of the people, garbage problem becomes increasingly conspicuous.668, China city, 2 ∕ 3
It is surrounded by rubbish band.Scrap glass is one kind of house refuse, it not only brought inconvenience to people's production and life, but also to ring
Border causes pollution, while also occupying valuable land resource, increases carrying capacity of environment.According to statistics, China generates every year
About 4,500,000 ~ 7,500,000 tons of scrap glass, account for 3% ~ 5% or so of domestic waste total amount.How effectively a large amount of scrap glasses
It recycles, is a problem to be solved.
In conclusion paste body filling faces the problems such as material is insufficient, at high cost, filling mining technology is made to be difficult to comprehensive reality
It applies.And scrap glass recovery utilization rate is low, large area accumulation, causes environmental pollution, if scrap glass preparation can be made full use of full
The filler that sufficient coal mine requires, makes scrap glass turn waste into wealth, is a kind of effective method.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of method for preparing coal mine paste filling material using scrap glass,
For recycling scrap glass completely, resource is on the one hand saved, environmental pollution is reduced, has been on the other hand coal mine filling
Exploitation provides cheap raw material, and the performance of filler is improved while reducing filling cost, is filling technique
It implements in full and lays a good foundation.
The present invention is achieved through the following technical solutions: a kind of to prepare coal mine paste filling material using scrap glass
Method includes the following steps:
S1. it collects and scrap glass and is crushed, obtaining scrap glass micro mist that partial size is 0~1mm and partial size is 1~5mm's
Scrap glass fine aggregate, wherein the two respectively accounts for 50% according to weight ratio and mixed and be sufficiently stirred to obtain scrap glass mixing bone
Expect spare；
S2. it collects gangue and is crushed, so that the grain diameter of gangue is no more than 15mm after broken, further to gained
Coal gangue particle is sieved, respectively obtain partial size be 0~5mm fine aggregate, partial size be 5~10mm middle aggregate and partial size be
The coarse aggregate of 10~15mm；It according to the weight proportion of three is respectively 30%, 35% and 35% by fine aggregate, middle aggregate and coarse aggregate
It is stirred to obtain spare after gangue mixture；
S3. it is spare to collect flyash；
S4. take cement with scrap glass mixing aggregate made from above-mentioned steps, gangue mixture, flyash according to certain ratio
Water is added after being mixed in example, and further stirs evenly, and finally obtains coal mine paste filling material, wherein coal shared by each component
The weight proportion of mine paste filling material are as follows:
Scrap glass 10%~20%
Gangue 40%~50%
Flyash 10%~20%
Cement 10%~20%
Water 12%~25%
The mass concentration of coal mine paste filling material is 75%~88%.
The cement is the ordinary portland cement of label 425.
The jaw crusher that gangue uses is crushed, by broken gangue using vibrating screen progress fine aggregate,
The screening of middle aggregate and coarse aggregate, the vibrating screen that wherein screening of fine aggregate is 5mm using mesh diameter, the screening benefit of middle aggregate
The vibrating screen for being 10mm with mesh diameter, the vibrating screen that the screening of coarse aggregate is 15mm using mesh diameter, partial size are greater than 15mm
Aggregate be put into crusher carry out again be crushed after give over to it is spare.
The novel specified features having of the present invention and beneficial effect are:
The present invention realizes the technology that coal mine paste filling material is prepared using scrap glass, has obtained scrap glass adequately
It recycles, solves the pollution to environment, while having widened the source of filler, reduce filling cost, opened for filling
Implementing in full for technology is adopted to lay a good foundation；Scrap glass mixing aggregate can control the further hair of coal mine filling lotion crackle
Exhibition, to improve crack resistance, simultaneously because the tensile strength of glass is big, elongation percentage is big, make coal mine paste filling material tension,
Bending resistance, impact strength and elongation percentage and toughness are improved, and are effectively improved mobility, the elasticity of coal mine paste filling material
Modulus, Poisson's ratio and intensity.
