Description
Technical field
The invention belongs to coal separation technical field, it is related to coal separation production, especially a kind of underground coal preparation plant production method
And system.
Background technology
Traditional Coal Mine Design is in coal mining activity, and raw coal is typically only done after thick tear reason in underground by lifting system or belt
Conveyer transport rises to carries out washing operation again behind ground.Industrial sites coal preparation plant generally requires construction run coal bin, sieving approach
Workshop, main building, press filtration workshop, product storehouse, concentration basin and pump house and related auxiliary equipment.Coal preparation plant covers an area of tens of
Hectare, and construction of coal mine factory site is generally remote country or mountain area gully, for remote country, expropriation of land and difficulty of removing are costly,
For mountain area gully, industrial sites are narrow, cut into a mountain costly with bank protection.To such situation, in surface construction, coal preparation plant runs into
Problem and challenge.
In addition, colliery can produce substantial amounts of solid waste spoil in construction and production process, traditional mode is straight
Connect and be stacked at earth's surface, form hillock.The spoil of accumulation on ground surface brings very big threat and danger to mining area ecological environment and condition
Evil, including appropriation of land, cause pollution of air ambient, water quality and soil etc..With the raising of environmental consciousness, exploited thecoal mine mistake
The environmental standard and related request of journey are increasingly strict, and the negative effect such as environmental pollution is increasingly difficult to be received, or even has influence on
The existence in colliery.
There are many collieries the country by being backfilled under waste shaft as the major measure for reducing spoil discharge at present, cash after washing
Stone is gone into the well backfill by assistant conveyance, and this partial invalidity lifting and transport add production cost, also reduce the reality of mine
Production capacity.Particularly with the mine that ature of coal is poor, spoil content seriously constrains greatly the production capacity in colliery, if reducing carrying for spoil
Rising amount, equivalent to adding mine capacity.
The domestic application for underground discharge refuse technology at present has some examples, and it is generally the pre- discharge refuse operation of raw coal, in Shanxi
Middle energy Xing is eastern, and colliery applies jigging discharge refuse technique, and shallow slot dense medium discharge refuse technique is applied in new river in Shangdong Province Mining Group Ji Yangkuang,
But the case study on implementation in underground is all built without whole coal preparation plant's production system so far.
The content of the invention
It is an object of the invention to the limitation and difficulty for overcoming above-mentioned prior art, there is provided a kind of production of underground coal preparation plant
Method and system, it is integrally built coal preparation plant in underground, mine and the unified consideration of coal preparation plant, and product, which passes through to be lifted, after washing is
System or Leather Belt Conveyance rise to spoil after flooring product storehouse, washing and are directly used in underground filling goaf.
The purpose of the present invention is achieved through the following technical solutions：
Present invention firstly provides a kind of underground coal separation production method：This method is by construction of coal preparation plant in many behind underground, washing
Kind product coal rises to spoil after flooring product storehouse, washing by lifting system or Leather Belt Conveyance and is directly used in underground filling
Goaf.
Further, above coal preparation plant production method is sorted using lump coal dense-medium shallow-tank, smalls not washing, and coarse slime is using dense
Contracting classifying cyclone and high-frequency screen are reclaimed, and fine coal slurry is reclaimed using filter press, and coal preparation plant realizes closed water circuit.
The present invention also proposes a kind of underground coal preparation plant production system for being used to realize the above method：Including run coal bin, screening
Chamber, shallow slot master wash chamber, slime water system chamber, press filtration chamber, mixed coal storehouse, cleaned coal storehouse, main shaft, spoil de-mediated chamber, cash
Ribbon conveyer tunnel between stone storehouse and each storehouse of connection and chamber；It is defeated that the upper end of the run coal bin is connected with run coal bin belt
Machine tunnel is sent, the run coal bin lower end is connected to screening chamber by run coal bin to chamber ribbon conveyer tunnel is sieved；It is described
Screening chamber by sieve chamber to it is main wash chamber ribbon conveyer tunnel and be connected to shallow slot master wash chamber；Screening chamber also passes through
Screening chamber to mixed coal storehouse ribbon conveyer tunnel is connected to mixed coal storehouse；It is defeated by cleaned coal reprinting belt that the shallow slot master washes chamber
The machine tunnel of sending is connected to screening chamber to mixed coal storehouse ribbon conveyer tunnel；The slime water system chamber is connected by press filtration chamber
Screening chamber is connected to mixed coal storehouse ribbon conveyer tunnel.The upper end in the mixed coal storehouse passes through mixed coal storehouse to cleaned coal storehouse belt conveying
Machine tunnel is connected to the upper end of cleaned coal storehouse；The lower end in the mixed coal storehouse is connected under cleaned coal storehouse by Loading conveyer tunnel
End；The upper end of the cleaned coal storehouse is connected to main shaft by coal bunker connection roadway suitable for reading；The lower end Loading conveyer tunnel of cleaned coal storehouse
It is connected to main shaft；The spoil de-mediated chamber is connected to the upper end of waste bin by upper waste bin ribbon conveyer tunnel；It is described
The lower end of waste bin is connected with gangue reprint ribbon conveyer tunnel.
Further, above-mentioned run coal bin, mixed coal storehouse, cleaned coal storehouse and main shaft are in " " a font arrangement, production system of underground coal preparation plant
System and ribbon conveyer tunnel are serially connected in main conveying system side and arranged in " day " font；Wherein, screening chamber is located at main transport
On circuit, it is parallel with it positioned at main transport roadway side that shallow slot master washes chamber and slime water system chamber.
Further, production raw coal is transported to run coal bin by upper run coal bin ribbon conveyer, after run coal bin is stored, raw coal
Screening chamber is transported to through ribbon conveyer under storehouse, the block raw coal after classification is transported to shallow slot master by ribbon conveyer by screening chamber
The cleaned coal washed after chamber, coal slime and washing reprints ribbon conveyer by cleaned coal and returns to screening chamber to mixed coal storehouse ribbon conveyer
Tunnel；Mixed coal storehouse is directly transported to by ribbon conveyer after smalls is mixed with coal slime after classification, cleaned coal then reprint after by mixed coal storehouse
Cleaned coal storehouse is transported to cleaned coal storehouse ribbon conveyer tunnel.
Further, mixed coal and cleaned coal enter after mixed coal storehouse and cleaned coal storehouse buffering respectively through mixed coal and cleaned coal Loading conveyer respectively
