FIELD: mining.SUBSTANCE: sealer of shot-holes for control gas content of coal-beds comprising a sealing element made in the form of a rigid tubular housing with the end nipple supports and the elastic cuff put on the housing. At that the cuff is mounted on the housing in its end nipple supports through the band. In addition, the sealer comprises a limiting element which is attached to the bottom-hole end of the sealing element, the means of ramming the sealant into the shot-hole, the monitoring and measurement unit, the air supply system with the air supply tubes, and two additional nipple supports. At that the sealer is additionally provided with an elastic sleeve, pressure plate and a punch. At that the rigid tubular housing is made in the form of individual tubular elements interconnected by threaded joint. In front of the nipple support of the first tubular element the elastic sleeve and the pressure plate are located, pressed by the punch mounted on the threaded joint on the outer side of the first tubular element. In addition, the air supply tubes are made passing through the nipple supports, and the elastic cuff is fixed additionally on the resilient sleeve.EFFECT: providing convenience in mounting the sealer in the shot-hole in the confined area of mine workings.1 dwg |
