Compared with other rigid supports, Tunnel Roof Support has the ability to be contracted, stable and reliable. It adapts to the load and deformation of soft surrounding rock, has high section utilizat

Steel arch support is a kind of passive support for coal mine support. It has high tensile strength and compressive strength, and at the same time has good toughness, high supporting force and strong

The tunnel roof support has obvious advantages over ordinary supports. The use of the tunnel roof support in life is still very wide, especially in the high ground pressure mine, which is mainly refle

As the national environmental protection and national policies become more and more popular, mining pits can no longer be purchased from natural pine forests but only artificial pine forests. Due to t

Mine roof support can not only significantly improve the support effect of roadway, but also enhance the stability of surrounding rock. Mine roof support can also save a lot of transportation and main

The research on the popularization and application of steel arch supports has improved the safe production conditions of mines and reduced production costs. It is in line with the national policy of r
