Energy-gathered water stemming bag for blasting hole plugging

Abstract

The utility model discloses an energy-gathered water stemming bag for blasting hole plugging, which comprises a cylindrical polyethylene plastic thin bag with a fixing sleeve sewed on the outer side, and a high-flexibility and high-elasticity rubber energy-gathered ring capable of being sleeved in the plastic thin bag fixing sleeve, so that the resistance of a bag body and a hole wall is improved during installation, and the bag body is prevented from sliding down in a vertical shot hole; during blasting, explosive force pushes the blister mud bag outwards and extrudes the bag body, the rubber energy-gathering ring on the bag body also expands along with the blister mud bag and is tightly attached to the wall of a blast hole, and the movement resistance of the blister mud bag is remarkably increased, so that the action time of detonation gas and detonation stress waves is prolonged, and the blasting effect is effectively improved. When being used for blasting of a vertical blast hole of a mine roof, the anti-dust stemming bag is not prone to sliding out of the vertical blast hole, has the advantages of being low in cost, good in anti-dust effect, capable of preventing electric sparks, sanitary, safe, convenient to use, good in hole blocking effect and the like, can replace a traditional latex stemming bag, and has remarkable economic benefits and social benefits.
