Mine roof support is a kind of support measure commonly involved in tunnel construction. The construction quality of roof support directly affects the installation, progress and enterprise image.

Steel arch support is a support measure to reinforce underground engineering after shaped steel is formed. The steel arch frame is processed on site and piled up in a centralized manner. The following

The steel mine support is beneficial to improve the stress state of the support, improve its bearing capacity and maintain the stability of surrounding rock. In order to ensure the safety of mine prod

1, the roof support of the mine strong compression resistance, a good lane. The mine roof support of roadway is tightly connected with iron clip, so that the support structure is rigorous and the pre

U-shaped steel support has the advantages of high initial support force, large support strength, easy installation, and not easy deformation, etc., so it is often used in the manufacture of tunnel fle

The steel arch support solves the problem of tunneling support. Compared with other rigid supports, the steel arch has the flexible, stable and reliable bearing capacity, ADAPTS to the load and deform
