Underground Roof Support is an important job in the mining industry, such as coal mines, and is used to protect the roof from collapsing in the mine. Below are the general steps to perform Underground Roof Support:
1. Conduct a roof stability assessment: Before Support Arch can be carried out, the stability of the underground roof needs to be assessed. This usually includes the inherent properties of the rock formation, such as strength, thickness, cracks, etc., and takes into account the effects of groundwater. The results of the assessment will help determine the appropriate support measures.
2. Selection of support materials: Based on the results of the roof stability assessment, suitable support materials will be selected. Common support materials include steel pipes, steel beams, steel wire mesh and timber. The strength, stability and corrosion resistance of the materials should be taken into consideration when selecting the materials.
3. Design the support programme: design the support programme according to the actual situation of the mine. This includes determining the location, method and spacing of the support. The support methods usually used include steel beam support,Steel Support Arch, lining support and so on. The deformation and stress distribution of the roof plate should be taken into account in the design to ensure the stability and reliability of the support structure.
4. Installation of support structure: According to the design programme, the support structure is installed. This involves drilling, anchoring and erecting support materials underground. The installation process needs to be carried out in strict accordance with the design requirements to ensure that the support structure is correctly installed and adjusted.
5. Monitoring and maintenance: After installation of the support structure, regular monitoring and maintenance work is required. This includes monitoring the stability of the support structure, timely detection and treatment of possible problems. The support materials also need to be regularly inspected and maintained to ensure effective performance.
It should be noted that the underground roof support is a complicated work, which needs to be designed and constructed by professionals. In actual operation, it must be carried out in strict accordance with relevant norms and safety operation requirements to ensure the quality and safety of the work.
