Untertage-Bergbau Verstärkung

Underground mining reinforcement material is using high-pressure perfusion for water shutoff, when mixed with resin and catalyst reaction or water generated when the expansion their reaction or generate multiple mesh density foam elastomer characteristics, when it was pushed high pressure, injected into the coal-rock or concrete cracks (under high pressure can crack open the closed coal bed), may be along the rock or coal Bringing concrete crack extension until all the cracks (including the eye imperceptible cracks and under high pressure to re-open the crack) filling. Sealing cracks in the rock reinforcement of coal, the coal-rock without a corresponding expansion of water when the product becomes smaller (expansion times of 1 to 5 times), high pressure thrust to underground mining reinforcement material and filled with all the pressure into the gap, to achieve the purpose Stop-leak , finished compression between 20 45Mpa; in after contact with water (mixed with water), the response associate, was expanded, the expansion pressure, seepage pressure under the action of the second (expansion multiple of 10 to 20 times), high pressure thrust and second osmotic pressure will be two kinds of liquid and filled with all the pressure into the gap, so as to achieve the purpose Stop-leak, finished compression between 10 20Mpa, it can be said that the product is plugging plugging material properties, especially the best one . Product Use: Reinforcement fracture and unstable ground; closed water entrance; compact formation; rock reinforcement; bolt seal.
