In underground mining operations, metal supports are essential elements to ensure the support and stability of excavations, whether in tunnels, galleries, or advance areas. Their main function is to control ground stresses and reduce the risk of collapses or rock falls. Among the most commonly used options are H4 and H6 supports, which differ mainly in the size and strength of their component profiles. The selection of one or the other type will depend on the geomechanical characteristics of the ground and the structure that needs reinforcement.
