Resilient Heracles is a friction stabilizer system and is commonly referred to as Resilient Heracles or Split Set design is used to firmly control hard or soft rock of underground Mining. As lateral ground movement increases, the system increases its superior holding power. Friction rock bolts produce superior holding power due to their unique design that exerts pressure against the rock over its full contact length immediately upon installation. When a ground shift occurs, our rock bolt conforms to the changing ground conditions. The result is a tight grip that actually grows stronger with time and ground movements, providing reliable ground support. An added advantage is that these friction bolts never needs tightening. The radial compression of the slotted steel tube inside the bore hole provides both radial and axial restraint to the rock movement.
