Metal Pillar
The type of metal pillar is a slightly increased resistance friction metal pillar, which is used to support the roof of the coal mining face. use. The metal pillar has the characteristics of high initial working resistance and large shrinkage. After the pillars are installed, the initial working resistance can be reached quickly and the support function of the roof can be exerted as early as possible. Type metal pillars can also be used on working surfaces where the roof has a large amount of subsidence and is subject to periodic pressure.
