The steel arch support belongs to a kind of supporting equipment. It is mainly used in mine tunnel supports and has the characteristics of high-pressure steel structure. At present, the steel arch support used in the mine is mainly U-shaped steel, which acts on the mine tunnel and roadway support of underground coal mines.
The steel arch support has the characteristics of high pressure resistance, long support time, easy installation and deformation.
Compared with other rigid supports, U-shaped steel arch supports have the characteristics of shrinkability and stable and reliable bearing capacity, and can well adapt to the load and deformation of soft surrounding rocks.
The U-shaped steel arch support has a high cross-section utilization rate, convenient bracket support, small maintenance, high bracket recovery and reuse rate, reduced use of pit wood, and obvious environmental benefits.
The main raw materials are U-shaped steel, which needs to be cut after cold-formed and then connected with U-shaped steel cables.
The U-shaped steel arch support is safe and reliable, and has the potential to effectively reduce the occurrence of accidents such as roof fall and gangs, and has made an important contribution to the stability of the mine ventilation system. At the same time, the U-shaped steel arch bracket can be used to better solve the problem of excavation and support.
