As an efficient and reasonable support method, the steel arch support is used in specific scenes as the surrounding rock pressure value used on the steel arch support reaches a certain value, the bracket will be compressed, so that the surrounding rock acts on the steel The pressure on the arch support drops, so that the surrounding rock pressure is greater than the bearing capacity of the steel arch support and the support is destroyed.
The steel arch support is a supporting tool widely used in mine roadways. Steel arch support has unparalleled advantages in complex areas deep in roadways or in loose coal seams. It has good mechanical properties, high tensile strength and compressive strength, and also has good toughness properties, high initial support force, large support strength, and can be used multiple times. Filling materials are needed between the steel arch support and the surrounding rock, the purpose is to make the steel arch support closely contact with the surrounding rock, improve the stress condition of the support, improve its bearing capacity and maintain the stability of the surrounding rock.
The above is the small science of steel arch support. In use, everyone should flexibly choose the model, structure and shed distance of the steel arch support according to the specific conditions on the site, correctly guide the construction of the steel arch support of the roadway, and ensure that the steel arch support is effective, Reliable work is of great significance for accelerating the tunneling speed, reducing the amount of roadway repairs later, ensuring safe production, extending the service life, obtaining better technical and economic benefits, and giving full play to the support performance of the steel arch support.
