The underground coal and gangue separation system and coal and gangue separation method is provided to allow underground separation and separate storage of a coal-gangue mixture, the fact that the original underground wash-dressing process is complex, equipment is too large and wash-dressing capacity is low is improved, the coal-gangue mixture conveying problem and gangue surface stacking problem are solved thoroughly, ineffective lifting and conveying of a mine are greatly reduced, and green mining is truly achieved.
Description
Technical field
The present invention relates to downhole coal mine auxiliary equipment field, particularly a kind of down-hole bastard coal separation system and
Bastard coal method for separating.
Background technology
Along with the continuous exploitation of mine, the exploitation ratio of complicated seam and girdle strengthens, in raw coal
Spoil amount increases, and ash, moisture improve year by year.Shaft production raw coal is all carried by auxiliary shaft for a long time
Rising to ground washery and carry out washing, after washing, spoil is accumulated to hillock, not only adds in raw coal
The freight charges of spoil and discharge refuse expense, the hoisting power causing mine is nervous, and ton coal profit declines, and
And spoil discharge land occupation, also further result in the pollution of ground environment, be unfavorable for living environment
Improve.In recent years, along with green filling mining vigorously implemented by mine, established ground and delivered directly down-hole
Spoil is holed, and hillock spoil, after broken, reprinted and implemented to goaf faced by underground filling work
Filling, causes that spoil in raw coal is the most counter after being transported to aboveground washing out with raw coal is transported to down-hole, is greatly increased
The production cost of mine, it is imperative that washing system is set up in down-hole.And washing system is set up in down-hole,
Down-hole limited space need to be faced, produce that complex conditions, washing appliance be relatively big, the process energy of washing appliance
Power is difficult to, with ore deposit capacity of well, problems such as mating.

The buoyancy arrived is equal to the gravity of ore particle and the difference of same volume medium gravity.Dense-medium shallow-tank separator 56 is exactly
Utilize the equipment that coal is sorted by above-mentioned ultimate principle, due to suspension proportion more than water (therefore claim
For dense media) and can be adjusted according to the ature of coal that difference requires.In raw coal enters sorting groove,
Float less than the cleaned coal of medium proportion and discharge with medium overflow, and sink also higher than the spoil of medium proportion
Discharged by the scraper plate of transverse movement, make coal separate with spoil.Go up endlessly owing to having in sorting groove
Rise supplementing of medium stream and horizontal media stream, be allowed on the one hand produce overflow, on the other hand by level stream
The complex media motion stream raw with rising miscarriage destroys superposed layer, makes coal increase more smoothly, reaches
Coal separates with spoil.
It is only the preferred embodiment of the present invention by the above, it is noted that for the art
Those of ordinary skill for, under the premise without departing from the principles of the invention, it is also possible to make some changing
Entering and retouch, these improvements and modifications also should be regarded as protection scope of the present invention.
