Abstract

L'invention concerne un système de commande permettant d'éviter la roche non voulue, destiné à l'exploitation de minéraux solides, faisant appel à un détecteur de roche/interface minérale à balayage frontal, et permettant de commander au mineur d'exploiter la roche/interface minérale détectée. Un ou plusieurs détecteurs blindés à rayons gamma sont positionnés à proximité du mécanisme d'exploitation, et se déplacent avec le mécanisme d'exploitation de sorte que la taille angulaire du champ de vision ne soit pas réduite. Des déplacements angulaires des mécanismes d'exploitation sont mesurés et utilisés pour calculer l'emplacement de la roche/interface minérale. Un dispositif est intégré à l'intérieur d'un détecteur de roche blindé, pour détecter des déplacements angulaires du bras du mécanisme d'exploitation, et pour mettre en corrélation les changements au niveau du rayonnement gamma avec les déplacements angulaires, à l'intérieur de plages d'énergie sélectionnées. L'épaisseur du charbon restant est calculée au moyen de la mesure du taux auquel le rayonnement gamma augmente. Dans un mode de réalisation, des détecteurs de roche sont utilisés pour diriger l'exploitation du tambour de treuil avant et/ou du tambour de treuil arrière d'un système d'exploitation par longue taille.
