Mine Roof Support is a simple and practical supporting equipment for mine roadway. It has a simple structure and can be recycled. Underground Roof Support is under pressure, long-lasting support, easy to install and not easily deformed. Solved the problem of tunneling support. It has shrinkage, stable and reliable load-bearing capacity, adapts to the load and deformation of soft surrounding rock, high section utilization, convenient support of brackets, small maintenance, Mine Roof Support high recycling rate, reduced use of pit wood, environmental benefits Very obvious.
Underground Roof Support component
1.Underground Roof Support: The top beam is a circular arch, the number of which depends on the section size of the roadway, the force of the bracket, and the transportation conditions.
2.Underground Roof Support: There are three types of legs: one is the upper part of the arc shape, the lower part is the straight line section; the second type is all curved and has only one radius of curvature; the third is all Curved, but with two radii of curvature. A base is welded under the column leg, and the size of the base depends on the hardness of the bottom plate;
3.Underground Roof Support: The connecting piece is the clamping device between the bracket section and the inter-section. It can be used for the connection between the joints. It can also press the two sections of the connected steel joints to provide the pre-tightening force to make the U-shaped steel. There is friction between them to ensure that the arched bracket has a certain working resistance and a certain amount of shrinkage.
4.Underground Roof Support: The function of the inter-rack is to enhance the overall relative stability of the bracket. The brackets are connected from the longitudinal direction to form a whole.
5.Underground Roof Support Backing material: The backing material is the filling material between the Mine Roof Support and the surrounding rock. The purpose is to make the U-shaped steel bracket close to the surrounding rock, improve the bearing condition of the bracket and improve its bearing capacity. Maintain the stability of the surrounding rock.
