Abstract

Un perno de fricción (10) incluye un primer tubo generalmente circular (12) que tiene un diámetro interno y define una división longitudinal, en donde el tubo es radialmente expandible. El perno tiene un primer extremo delantero (16) para su inserción en un pozo (50), un segundo extremo que define una cabeza (18), y un segundo tubo generalmente circular que define una división longitudinal y que tiene un diámetro externo que es sustancialmente el mismo que o mayor que el diámetro interno del primer tubo generalmente circular. El segundo tubo está situado dentro del primer tubo (12) con el exterior del segundo tubo en contacto con el interior del primer tubo (12). El perno de fricción (10) se instala en una pared de roca (80) usando equipos y métodos estándares para la instalación de pernos de fricción (10).
