Profile of Shed Tunnel Steel Arch Support
Safety problem has always been a priority of mine enterprise, choose high quality mining equipment is particularly important, how to select the mine barrack bracket that should be many problems when the choose and buy, let me and all of you take a look at some notes of choose and buy of barrack stents. Barrack stent is mainly used for mine, mine roadway secondary supporting of roadway, and mountain tunnel support support purposes. Shed support is used to effectively reduce the roof caving, help such as accidents, safe and reliable, and enhances the stability of the mine ventilation system. Choose barrack support flexible support, better solved the difficult problem of the excavation support.
Application of Shed Tunnel Steel Arch Support
Shed support is mainly used for mine, mine roadway secondary supporting of roadway, and mountain tunnel support support purposes.
Characteristic of Shed Support
Shed support could withstand high pressure, support long time, are easy to install easy deformation,etc.
Compared with other support ,shed support has a more scalable and reliable carrying capacity accommodate loads and deformation of soft rock. Shed bracket section utilization is high, easy to stand back support small amount of maintenance.
Shed support recycling reuse rate, reduce prop use, environmental benefits are clear.
