Explanation of u-shaped steel support steps
1. U-shaped steel support U-shaped steel support is simple in structure, strong in support capacity, removable, and reusable. It is a mine underground support equipment. At present, there are three types of commonly used models, U25 and U36; During safe u-shaped mining, the coal mine only needs to prepare for driving the column in advance, then the outgoing roof is supported by anchor cable on the anchor bolt, and the U-shaped cover is used on both sides of the roof to support the roof with wood, and then the frequency maintenance of the roof is strengthened to open the u-shaped soft rock in the unstable thick coal seam. Compared with other rigid supports, U-shaped steel supports have the characteristics of scalability and reliability, adapt to the load and deformation of soft surrounding rock, have high section utilization rate, convenient support back, small maintenance, high bracket recycling rate, reduce the use of pit materials, and have obvious environmental benefits.
2. U-shaped steel support, u-shaped steel support in the application of mining roadway bifurcation point has achieved remarkable results, by the majority of mining machinery industry.
