Mining and Tunneling Expansion Shell Anchor
Mining and Tunneling Expansion Shell Anchor geometry showing the internal and external forces Eq. (1) indicates that the friction angle for the interface between the cone and the inner leaf surface must be less than the friction angle for the interface between the outer shell and the rock by an amount greater than the taper angle of the cone and inner leaf interface. In many cases, this condition is unlikely to be achieved because anchors are manufactured from cast components with an inherent roughness; the friction angle associated with this less than smooth surface is then often increased following zinc coating.
