Abstract

Un perno para mina incluye un cuerpo alargado que posee un primer extremo y un segundo extremo dispuesto en direccion opuesta al primer extremo, en donde el cuerpo alargado posee una primera seccion roscada, una segunda seccion roscada, y una seccion no roscada dispuesta entre la primera seccion roscada y la segunda seccion roscada. La seccion no roscada esta configurada para deformarse bajo carga cuando el perno para mina se instala con lechada en una perforacion.
