Abstract

L'invention décrit une pluralité de conceptions de boulons-câbles de soutènement de plafond de mine. Chaque boulon-câble de soutènement comprend un câble souple à plusieurs torons présentant une première et une seconde extrémité avec une tête d'entraînement formée sur la première extrémité, la tête d'entraînement présentant une pluralité de faces d'entraînement sur la surface extérieure de celle-ci. Dans un mode de réalisation de la présente invention, la tête d'entraînement peut être formée d'un seul tenant avec le câble à plusieurs torons. Un autre mode de réalisation de la présente invention forme une tête d'entraînement sous la forme d'un élément séparé. Avec une tête d'entraînement séparée, un ensemble de corps cylindrique et coin peut être rattaché au câble, la tête d'entraînement étant utilisée essentiellement pour faire tourner le câble.
