Mine Roof Support is a key measure to ensure the stability and safety of the top of the mine. The following are some common Steel Mine Supports methods:
1. Anchor support: The use of anchors for Mine Roof Support is a common method. This method forms an anchor support system by drilling holes in the roof and injecting anchors and curing materials. The function of anchors is to increase the strength and stability of the roof slab and share part of the roof load.
2. Beam and column support: For mines with large openings, beam and column support can be used. This kind of support method increases the stability and strength of the roof plate by setting a combination of beams and vertical pillars on the roof plate and transferring the roof plate bearing capacity to the pillars, thus increasing the stability and strength of the roof plate.
3. Steel Arch Support: Steel Arch Support is a commonly used method of mine roof support. This method uses prefabricated steel arches or welded steel arches on site, which are installed on the roof plate, and can effectively disperse the roof plate load and geological force, and enhance the stability of the roof plate.
4. Precast concrete slab support: For larger openings and longer mines, precast concrete slabs can be used for Support Arch . This method is to prefabricate concrete slabs outside the site and install them on the roof with lifting equipment or bulldozers to increase the strength and stability of the roof.
5. Mine road timber support: Mine road timber support is a traditional and effective support method. It uses timber or synthetic material as the roof support material, and the type and size of timber can be adjusted according to the need to enhance the stability and bearing capacity of the roof.
Before carrying out Mine Roof Support, it is crucial to carry out geological investigation and assessment to understand the geological conditions and mechanical properties of the roof slab. During the design and construction of the support, relevant safety standards and codes should be followed and proper monitoring and maintenance should be carried out to ensure the safety and stability of the mine roof.
