Mine roof support can be said to be the most important support profile in coal mines and the key to roadway support. The coal mine roof support that was laid earlier may be aging and loose. The mine roof support is retractable, which can play a supporting role and replace the old and new!
Mine roof supports with high pressure, long support time, easy installation and deformation.
Compared with other rigid supports, U-shaped steel supports have the advantages of shrinkability and stable and reliable bearing capacity, and can adapt to the load and deformation of soft surrounding rocks.
The utilization ratio of the support section at the top of the mine is high, the support is easy to support, the maintenance is small, the recovery and reuse rate of the support is high, the use of pit wood is reduced, and the environmental protection benefit is obvious.
Mine roof supports are also called mine support steels, which are mainly used to make U-shaped steel supports or arched steel sheds, which are used to support mine shafts and roadways.
