Steel mine supports refers to the artificial structure installed in the mine roadway to support the rock. Its function is to control the movement of surrounding rock and prevent it from falling, so as to keep the safe use space of roadway. According to the service time, there are temporary supports and permanent supports; According to the mechanical properties of the rigid and flexible support; According to material cent has wood, metal, stone material, reinforced concrete bracket to wait.
Compared with other rigid supports, steel mine supports have flexible, stable and reliable bearing capacity, adapt to the load and deformation of soft surrounding rock, high utilization rate of section, convenient return of mine supports, small amount of maintenance, high recycling reuse rate of supports, reduce the use of pit wood, and obvious environmental benefits. The use of mine support is safe and reliable, which can effectively reduce the occurrence of roof caving and strip side accidents, and improve the stability of mine ventilation system.
