Embodiment 1
[0050] When applied to a full-height mining face, the roof caving type gangue filling hydraulic support provided by the present invention is arranged in a row on the coal mining face, and the bottom unloading gangue leaking scrapers 7 are connected with each other to form a bottom unloading gangue leaking scraper conveyor , before recovery, adjust the height of the straddle platform 6 through the plug-type telescopic structure according to the mining height of the working face, so that the height of the straddle platform 6 meets the filling height requirements, and does not interfere with the support cylinder 41 at the same time. The gangue filling hydraulic support moves forward, the roof collapsed rock block 81 is not strung into the filling space under the cover of the cover beam 2, and the gangue filling material is transported by the belt to the end of the bottom dumping gangue leaking scraper 7, and the bottom dumping gangue leaking scraper 7. After the conveyor is starte...
Embodiment 2
[0052] When applied to the top coal caving mining working face, the roof caving type gangue filling hydraulic support provided by the present invention is arranged in a row on the coal mining working face, and the bottom unloading gangue leaking scrapers 7 are connected with each other to form the bottom unloading gangue leaking scraper conveying machine, before recovery, adjust the height of the straddle platform 6 through the plug-type telescopic structure according to the mining height of the working face, so that the height of the straddle platform 6 meets the filling height requirements, and does not interfere with the support cylinder 41 at the same time. The gangue filling hydraulic support moves forward, and the roof collapsed coal blocks 81 are not strung into the filling space under the cover of the cover beam 2, and the gangue filling material is transported to the end of the bottom discharge scraper 7 through the belt, and the bottom discharge scraper scraper 7 Afte...
