Description
Technical field
The utility model belongs to coal coal preparation technology field, and it is related to a kind of intelligent dry method discharge refuse applied to underground coal mine
System, its be applied to underground gangue preferential separation and based on coal it is different from gangue density utilize X ray and dot matrix spy
Survey device and supersonic range finder synergy ONLINE RECOGNITION coal and gangue and sorted.
Background technology
Gangue is the accompaniment in coal production, process, and low, the harmful material of caloric value is more, has a strong impact on product matter
Amount, it is necessary to be identified and sort in time.In conventional coal underground mining, spoil is transported to ground together with coal and divided
Choosing, wastes amount transport, the manpower and materials of lifting, and the spoil after sorting is piled into mountain, land occupation, pollutes environment.If
The spoil in raw coal is excluded into not gug in underground, cash condition is abandoned for some undergrounds or new work is filled using downhole gangue
The mine of skill, undoubtedly have and have very great significance.The particularly continuous improvement of mining mechanization degree in recent years, by underground work
Make bedding fault or dirt band be largely mixed into raw coal, especially the extensive use of caving Mining Technology, make coal ash unstable,
Raw coal quality declines, and market sale difficulty is big, have impact on Business Economic Benefit；Mine runs into control coal ash simultaneously
Often give up during tomography and do not adopt, cause working face extraction rate low, not only waste of resource, and shorten the length of service of mine.
In the prior art, typically sorted because underground coal mine condition is limited using very limited amount of spoil, such as have weight at present
Medium shallow-tank separator underground waste stone exhaust system, movable-sieve jig underground waste stone exhaust system etc., it is preliminary that this substantially namely carries out spoil
Sort (ragging), effectively spoil separation can not be carried out；Coal after being separated using this equipment can also be mixed with a large amount of spoils,
Secondary separation or sorting must be carried out on well, in turn results in the repetition and waste of resource.This external cause dense-medium shallow-tank waste stone exhaust system technique

Coal or the method for compound dry method (selection by winnowing) coal separation remove the gangue in coal, for lumped coal and gangue, the knowledge of prior art
Other method mainly has several, these recognition methods such as manual sorting, image-recognizing method, gamma ray identification and X ray identification
There are the advantages of respective and production accommodation, but have the defects of certain or deficiency.Such as manually sorted, generally deposit
It is that labor intensity is big, operating environment is severe, efficiency is low in problem；Image-recognizing method is according to the color of coal and gangue ash
Degree is identified, and problem be present is to be difficult to and black gangue as coal facies；Generally used in ore recognition imaging technology
Linear array detector, and linear array detector pixel is more, data processing amount is big, it is necessary to be equipped with industrial computer specially to handle, and in addition can not
Solve the influence of material particular diameter size, be not suitable with the specific use environment in colliery.
