The utility model is to adopt following technical scheme to realize: special hydraulic support for underground filling coal mining of coal mine, comprise base, the base top is provided with back timber, the front-end and back-end of back timber are respectively equipped with forestope and back tail boom, being with first oil cylinder of fore-and-aft direction placement and the rear end and the forestope of first oil cylinder in the forestope fixes, the front end of first oil cylinder is fixed with the front stretching beam, the front end of front stretching beam is hinged with face guard, the below of first oil cylinder is provided with rear end and the fixing driving oil cylinder of forestope, the front end and the face guard of driving oil cylinder are hinged, and the rear side of base is fixed with compaction apparatus.Compaction apparatus is that those skilled in the art realize easily.During work, the hydraulic support group that some special hydraulic support for underground filling coal mining of coal mine are formed is placed on the work plane, and support is divided into former and later two working regions, and the front portion is the coal mining activity district, and the rear portion is the packing job district.The filling compacting operation is carried out at the rear portion when being mined in the bank by coal-winning machine during operation, along with coal-winning machine constantly along the left and right directions coal cutting, driving first oil cylinder that the special hydraulic support for underground filling coal mining of coal mine of the bank correspondence after the coal cutting is synchronous and driving oil cylinder elongation, thereby the drive extensible canopy stretches out and withstands the bank, drive the driving oil cylinder elongation then face guard is ejected, play the effect of goaf after the coal cutting being carried out supporting; Meanwhile, under the supporting role of back tail boom, compaction apparatus carries out compacting with filler; When coal-winning machine has cut a cutter coal to the bank after, by hydraulic mechanism the driving oil cylinder on each special hydraulic support for underground filling coal mining of coal mine is shunk, and then face guard regained, then driving the contraction of first oil cylinder and driving oil cylinder regains the front stretching beam, then with the whole reach of special hydraulic support group, repeat above-mentioned steps repeatedly, can satisfy the requirement of the synchronization job of pack builders' skill and coal winning technology, for its synchronization job provides rational supporting and working space.
Be hung with drag conveyor on the back tail boom, during work, filler be transported to drag conveyor, then under the effect of drag conveyor, filler is transported to the coal mining goaf, thereby realize the coal mining goaf is provided the purpose of filler.
The compaction apparatus top is provided with belt conveyer, the place ahead of belt conveyer is provided with filler side dumping plate, during filling, filler can be transported on the belt of belt conveyer, by filler side dumping plate filler be pushed the coal mining goaf then and carry out compacting operation.
Being with second oil cylinder of left and right directions placement and the front end of second oil cylinder in the back tail boom fixes with the back tail boom, the rear end of second oil cylinder is fixed with the back extensible canopy, the rear end of back extensible canopy is fixed with the push pedal that is positioned at tail boom outside, back, when compaction apparatus during with the filler compacting in goaf, then drive the elongation of second oil cylinder by hydraulic mechanism, back extensible canopy drives push pedal and moves reciprocatingly, and then with the filler compacting on top, coal mining goaf, has satisfied the requirement to the whole compacting in coal mining goaf.
The utility model has been filled up not to be had a kind ofly reasonable supporting to be provided and simultaneously filling process and equipment to be provided the blank of the hydraulic support of working space for coal winning technology at present, make filling process and coal winning technology synchronization job to carry out smoothly, operating efficiency has had substantial improvement, and by whole reach to the special hydraulic support group, personal safety to the workman when reducing labor intensity further ensures to have advantage rational in infrastructure, that cost is low and simple to operate simultaneously.
