The main application area of Tunnel Roof Support is in the coal mining industry. Its product performance is directly related to the safety of the coal mining industry. How is the Tunnel Roof Support product moved?
1. Single frame sequential type, also known as single frame continuous type, the bracket moves forward along the traction direction of the shearer, the moving step is equal to the depth of cut, and the bracket is moved into a straight line. This mode is simple to operate and easy to ensure the quality of the specification. Adapt to unstable roof, more applications; Tunnel Roof Support
2. Grouping interval staggered, this method has a fast moving speed and is suitable for a high-yield fully mechanized mining face with stable roof;
3. The whole group is sequentially ordered. This method is moved one by one in each order. Each group has two or three frames. Generally, there are large-flow electro-hydraulic valves in group control. The applicable coal seam geological conditions are good, and the coal mining machine can quickly pull coal. Nissan tons of fully mechanized mining face. Tunnel Roof Support
