| description | The utility model relates to a mine coal seam drilling hole packer, including the built -in class of buret who sets up at the middle part, the built -in pipe wall outside cover that flows buret is equipped with the steel wire capsule, be provided with the capsule cavity between built -in outer wall that flows buret and the steel wire capsule inner wall, the built -in buret front end that flows stretches out from steel wire capsule front end, steel wire capsule front end is connected with leading end, and leading end is fixed the steel wire capsule on the built -in buret of flowing, and steel wire capsule rear end is closely fixed on built -in flow steel pipe through rearmounted end. The utility model discloses mine coal seam drilling hole packer when the hole sealing capsule expands, can effectively improve the stress between its and drilling pore wall, and the reinforcing prevents to the sealed effect of drilling that gas from letting out from drilling, the characteristic of freely stretching out and drawing |
