Abstract: In order to pass through the change zone of gangue in the 12704 working face smoothly, in the process of
full high mining in medium and thick coal seam, the medium and deep hole loosening blasting technology is adopted,
and the length 180 m gangue area is passed smoothly. Save 88 d, effectively ensure the normal mining of the 12704
face.
Key words: fully mechanized mining; gangue-clamping; blasting
