Steel mine support 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.
Compared with other rigid supports,Steel mine support has the characteristics of scalability, stable and reliable bearing capacity, and can adapt to the load and deformation of soft surrounding rock. The section utilization rate of u-section steel support is high, the support is easy to support, the maintenance quantity is small, the recovery reuse rate is high, reduces the use of pit wood, the environmental protection benefit is very obvious, mainly used for mine roadway, secondary support and through the mountain tunnel support and other purposes. The use of steel mine support can effectively reduce the occurrence of roof caving and strip side accidents, which is safe and reliable and improves the stability of mine ventilation system. The U section steel can be used to solve the problem of tunneling support.
The mining support is divided into temporary support and permanent support according to the use time; 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.
