Description
Technical field
The present invention relates to filling in mine slurry technical field, and in particular to a kind of consolidated fill slurry fills underground goaf
Technique.
Background technology
By the use of gravity separation technology produce mine tailing as filling in mine material when, need to select factory produce rejects crush
Etc. handling process, below treatment to certain granularity, then mixed with cementing material be prepared into filling slurry be fills up to it is mined out
Area.And fine grain content is very low in the broken material of waste residue, broken material finish mix slurry poor fluidity, it is often necessary to which addition is a large amount of
Cement could be conveyed using force (forcing) pump.The country is to reduce cement consumption and improve filling slurry mobility, generally uses sieve
Point, the multistage technology flow such as broken, ore grinding, complete to reach above-mentioned purpose by various devices and equipment.Therefore related process needs volume
The outer increase flow such as ore grinding, thereby results in that whole facility floor space is larger, and capital expenditure is high, and operating cost is high, plant maintenance
It is complicated.
It is cementing that the A of Chinese patent CN 104696008 " method of Wasterock Cemented Filling underground stope " disclose a kind of rubble
The method for filling underground stope, effectively improves big and filling slurry poor fluidity the problem of cement consumption, but still suffer from as
Lower problem：
(1) rubble crushing system includes oscillating feeder, jaw crusher, toothed roll crusher, rotary screen, technological process
Complexity, one section of screening system is crushed using two sections, causes to invest excessive, and operating cost is high.
(2) metaling is milled into powder by the qualified metaling of 15mm using Raymond mill after crushing, to increase casting resin
Fine grained in slurry, improves casting resin level and matches somebody with somebody, and increased grinding flowsheet, causes technological process complicated, and operating cost is high.
(3) the bulky grain aggregate containing 15mm in filling slurry, is stirred using agitator, easily stirs insufficient,
Such as need stirring abundant, mixing time need to be increased, cause filling slurry to prepare discontinuous.
Therefore it is badly in need of developing the new filling slurry and filling process of a kind of intensity high, good fluidity, low cost.
The content of the invention
For above-mentioned problem, the present invention proposes the technique that a kind of consolidated fill slurry fills underground goaf,
Broken barren rock technological process in filling slurry preparation process is simplified, it is not necessary to grinding flowsheet, using the ore deposit for selecting factory's ore dressing to produce
Mud improves filling slurry level and matches somebody with somebody, and adjusts filling slurry stirring technique, realizes the continuity of filling slurry preparation, reduces and fills
Fill into this.
In order to realize above-mentioned purpose, the present invention uses following technical scheme：
A kind of consolidated fill slurry fills the technique of underground goaf, and step is as follows：
1) will select factory produce mine tailing waste residue from refuse bin release, and by adhesive tape conveyor transport to sifting vibrating sieve into
Row first paragraph is sieved；
2) thin material under sieve is sent in sandstone finished product bin through adhesive tape conveyor, thick material is through adhesive tape conveyor on sieve
Feeding disintegrating machine, delivering to sifting vibrating sieve after crushing again through adhesive tape conveyor carries out second segment screening；
3) repeat step 2) to material all by sifting vibrating sieve；
4) the thin material in finished product sand material storehouse is delivered to filling slurry stirring system through disk feeder, then by than
Example by sludge slurry, cementing material and appropriate water addition filling slurry stirring system, obtains filling slurry respectively after stirring；
5) filling slurry is sent by pumping to underground goaf, you can.
Preferably, the refuse bin bottom is provided with the ore drawing valve of discharging.
Preferably, step 1), 3) in sifting vibrating sieve be circular vibrating screen.
Preferably, the circular vibrating screen mesh size is 5mm.
Preferably, step 2) described in disintegrating machine be vertical shaft crusher.
Preferably, step 4) in by sludge slurry add filling slurry stirring system be specially will first select factory produce sludge starch
It is sent by pumping in sludge dashpot, is then added in filling slurry stirring system by pumping.
Preferably, sludge slurry first uses the dense treatment of concentrator before sludge dashpot is delivered to.
Preferably, step 4) in by cementing material add filling slurry stirring system it is micro- specifically by cementing bin bottom
Powder scale is quantitatively added in filling slurry stirring system.
Preferably, step 4) in filling slurry stirring system be made up of two sections of continuous mixers.
Preferably, two sections of continuous mixers are horizontal mixer.
Due to using above-mentioned technical scheme, the beneficial effects of the invention are as follows：Prepared this invention simplifies filling slurry
Barren rock technological process is crushed in journey, it is not necessary to grinding flowsheet, improving filling slurry level using the sludge slurry for selecting factory's ore dressing to produce matches somebody with somebody,
Adjustment filling slurry stirring technique, realizes the continuity of filling slurry preparation, reduces filling cost.
(1) to only have ore drawing valve, circular vibrating screen, vertical shaft crusher and each technology room material defeated for rejects crushing system
Send and constituted with adhesive tape conveyor, technological process is simplified, using prescreening system so that disintegrating machine operating efficiency is higher, carries
Equipment functional reliability high, reduces investment, reduces filling cost.
(2) the sludge slurry for selecting factory originally to produce need to drain into tailings reservoir for piling using dry after dense, press filtration, and the present invention will select factory
The sludge slurry of generation saves Liao Xuan factory and office reason sludge slurry pressure by being added directly to filling slurry preparation system after dense, on the one hand
Filter and tailings reservoir for piling cost, it is real to realize that the sludge for selecting factory to produce slurry, mine tailing waste residue are recycled, eliminate sludge slurry and
The influence that mine tailing waste residue is caused to environment；On the other hand improve filling slurry level using sludge slurry to match somebody with somebody, that realizes filling slurry can
Transporting, is improved filling slurry level using primary grinding generation fine fraction powder and matched somebody with somebody relative to prior art, has saved ore grinding
Cost, simplifies technological process, reduces filling cost.
(3) filling slurry prepares stirring system using two sections of Horizontal stirrings, is stirred using agitator relative to prior art,
Realize stirring work continuity so that filling slurry stirring more fully, reduces the possibility that material conveys plugging, improves
Filling slurry can transporting.
