Abstract
Description
Technical Field
[0001] This utility model relates to the field of downhole support, specifically a downhole support metal mesh with a reinforced structure. Background Technology
[0002] In underground mining, the stability of the roadway is crucial. To prevent accidents such as collapse and deformation of the surrounding rock, support structures are typically used to reinforce the roadway. Metal mesh, as a common support material, has advantages such as high strength and good toughness, and is widely used in underground support. However, existing underground support metal mesh is prone to local deformation or even breakage under high surrounding rock pressure, leading to a decrease in support effectiveness. The metal mesh itself has a relatively simple structure, and local breakage of the mesh surface lacks supporting strength, failing to effectively perform its support function and also reducing underground safety.
