The specific embodiment
Describe sorting process of the present invention in detail according to Fig. 1.This waste rock discharging and sorting comprehensive treatment method for underground lump coal has fully utilized ripe aboveground moving grate size coal discharge refuse sorting technology and rolling disk sieve 2 commonly used, fixing equipment such as castor bar grizzl(e)y 3, high-frequency dewatering screen 5 and filter press 6, disposes the patented technology " down-hole mechanical movable-sieve jig " (patent announcement number be CN101486012A) of the maturation that the inventor used at underworkings simultaneously.Wherein specification, the model of rolling disk sieve 2, high-frequency dewatering screen 5, filter press 6 etc. should be selected according to the actual needs in exploiting field and the relevant device supporting with it, and fixedly the specification of castor bar grizzl(e)y 3 can be determined according to the desired grade of sorting raw coal of down-hole mechanical movable-sieve jig 4.
Below be a kind of specific implementation method of the present invention (as shown in Figure 1), the step of employing mainly is: treat that at first the sorting raw coal is transported to the tunnel of arranging rolling disk sieve 2 through raw coal supplied materials belt feeder 1, (present embodiment adopts by rolling disk sieve 2
50mm) carrying out classification handles.Rolling disk sieve 2 has efficiency of separation height, is difficult for advantages such as stifled sieve aperture.In addition, rolling disk sieves that 2 volumes are little, and floor space is little, can decompose to be convenient to the down-hole transportation, to install.Coal by rolling disk sieve 2 is divided into two parts, and a part is 0～50mm screenings, directly enters down-hole original fortune coal belt feeder 9.If under conditions permit situations such as down-hole chamber size and vibration, above-mentioned rolling disk sieve 2 can replace with the better banana screen of separating effect.On the sieve+the grade lump coal of 50mm enters fixedly castor bar grizzl(e)y 3, and (present embodiment adopts
350mm) remove bulk technology, the above bulk otherwise processed of 350mm on the sieve, the lump coal of the following particle size fraction of 350mm enters down-hole mechanical movable-sieve jig 4 and carries out the discharge refuse sorting.Down-hole mechanical movable-sieve jig 4 is nucleus equipments of this lump coal discharge refuse sorting process, and it is to invent on the basis that ground coal preparation plant mechanical movable-sieve jig successfully uses.Owing to the influence in underworkings chamber space, limited the physical dimension of down-hole mechanical movable-sieve jig 4, on the core technology of using for reference the moving sieve in ground, down-hole mechanical movable-sieve jig 4 is manufactured the strip equipment that is adapted to be mounted within the underworkings chamber.The equipment total height is not higher than 7m, and the mechanical movable-sieve jig that general ground coal preparation plant selects for use is owing to the supporting layout with other equipment need highly reach 16～20m, so can not be used for the down-hole.And this equipment can decompose, so be convenient to down-hole transportation, installation.By the sorting of down-hole mechanical movable-sieve jig 4, be divided into and select two kinds of products, be i.e. lump coal and piece spoil.The lump coal that sub-elects is promoted to more than the water surface through the lump coal scratch board conveyor in the down-hole mechanical movable-sieve jig 4, is transported to tunnel lump coal belt feeder 8, is transported to down-hole coal store or direct gug.The piece spoil that sub-elects is promoted to more than the water surface through the spoil scratch board conveyor in the down-hole mechanical movable-sieve jig 4, is transported to tunnel spoil belt feeder 10, is transported to discarded tunnel, down-hole or downhole gangue filling system.Because the lump coal second-time breakage in transportation after the classification produces some fine grain coals, this part fine particulate coal sees through down-hole mechanical movable-sieve jig 4 in assorting room sieve plate is blended in the lump coal, is transported to lump coal together and enters tunnel lump coal belt feeder 8.
The movable-sieve jig separating medium is a water, and separating effect is played a decisive role.The black water that produces in the assorting room of this system comprises mainly that jigging machine overflow water, jigging machine regularly discharge water (according to on-site actual situations, general about five days discharging a wash water) and equipment breakdown discharges water etc.The treatment process of this part water is as follows: black water enters coal slime pond 11 by pipeline, and (present embodiment adopts to get to high-frequency dewatering screen 5 through coal slurrypump 7
0.5mm) cut thick after, enter coal slime pond 12 again, feed filter press 6 through coal slurrypump 7 and carry out processed, filter the filter cake that produces and lump coal by filter press 6 and mix and be transported to tunnel lump coal belt feeder 8; The filtrate of filter press 6 filterings enters circulating water pool 13, recycles in coal slurrypump 7 is got to down-hole mechanical movable-sieve jig 4, realizes the wash water closed cycle.Wash water is the carrier of lump coal separation, it how much have a strong impact on separating effect.In assorting room, because product is taken away a part of water, make wash water that certain loss be arranged, need to replenish in addition clear water.Mending amount of flush water has a small amount of overflow to be advisable with down-hole mechanical movable-sieve jig 4.
In addition, above-mentioned black water treatment process can suitably be simplified, adjust according to conditions down-hole, cancellation filter press 6.Black water recycles after high-frequency dewatering screen 5 is handled.Black water also can enter the down-hole sludge treating system and handle.Filter cake after the processing and lump coal mix and are transported to tunnel lump coal belt feeder 8.Filtrate after the processing enters circulating water pool 13, gets to down-hole mechanical movable-sieve jig 4 through coal slurrypump 7 and recycles, and realizes the wash water closed cycle.
Another characteristics of this technology are: set up the Coal Transport bypass.Between the raw coal supplied materials belt feeder 1 of conveying exploiting field raw coal and the pan feeding chute of rolling disk sieve 2 bifurcated chute is set, the trend by turnover panel (not shown) control coal stream can directly enter down-hole original fortune coal belt feeder 9.When down-hole moving sieve waste stone exhaust system breaks down, turnover panel is got to bifurcated chute.After can realizing moving sieve waste stone exhaust system scram, the down-hole raw coal still can transport by original system, does not influence the mine continuity and produces.
The present invention also provides filler for the underground filling process system, with the spoil fragmentation, as the roadside packing material, carries out gob side entry retaining filling wall as aggregate; The 2nd, be filled to the goaf, both saved the expense of spoil gug, increase economic efficiency.Reduced subsiding of the face of land again, environmental issues such as hillock occupation of land.Has good social benefit.
