Split Set Innovation in Mining Support, Cerro de Pasco

Description

The split set, also known as a friction bolt or anchor, is a common mechanical support used in underground mining and civil works to stabilize ground conditions. It consists of a steel tube with a longitudinal slit that is inserted into a borehole drilled in the rock. As it is driven in, the tube compresses and exerts constant pressure against the borehole walls, generating friction that firmly secures it in place. This immediate anchorage allows it to function effectively as a rock support system to prevent rock falls.
