Description

Underground supporting metal net with reinforcing structure Technical Field The utility model relates to the field of underground support, in particular to an underground support metal net with a reinforcing structure. Background In the underground mining process, the stability of the roadway is important, and in order to prevent accidents such as collapse, deformation and the like of surrounding rocks of the roadway, the roadway is usually reinforced by adopting a supporting structure. As a common supporting material, the metal net has the advantages of high strength, good toughness and the like, and is widely applied to underground supporting. The existing underground supporting metal net is easy to locally deform or even break when bearing larger surrounding rock pressure, so that the supporting effect is reduced, the structure of the metal net is simpler, the supporting strength is lacking when the net surface is locally broken, the supporting effect cannot be effectively exerted, and meanwhile, the underground safety is reduced. Disclosure of utility model The present utility model is directed to a downhole supporting metal mesh with a reinforcement structure, so as to solve the problems set forth in the background art.
