The underground roof support has shrinkage and stable and reliable bearing capacity compared with other rigid supports, and is more suitable for the load and deformation of the soft surrounding rock produced in mining. The use of wood is more easy to use and install, and with the improvement of the U-shaped steel production process, it can greatly improve the load-bearing capacity of mining steel supports.
When the new mine is being mined, you only need to prepare the top plate in advance to lay out the dots, and then anchor the rods row by row from the outside to the inside.The anchor cable supports the roof on both sides. It is usually enough to strengthen the frequency of roof maintenance. Underground roof supports are more mined in unstable soft and extra-thick mines. The conditions under the mine are complicated, and the support of the roadway brackets is uneven, especially some roadways with large deformation of the surrounding rock, which are easily affected by mining. The roadways at the fault fracture zone are the most popular underground roof brackets for mining. It is better to use the area to improve the mining environment and reduce the impact of the environment on the progress of the project.
