CA 2675077

The invention relates to a method for controlling the outward conveyance of debris extracted by mining machines operating in underground mining in a variety of locations of the mine structure via conveying means and bunker systems disposed in the mine structure, wherein the lowest available conveying capacity of the conveying means and the buffer capacity of the bunker systems are determined based on continuously captured actual data, and are compared in a computer-aided control unit to the current actual extraction output and/or the target extraction output anticipated for a predefined time period and/or the budgeted output extrapolated based on past actual data, wherein, if deviations are detected, the control unit automatically brings about a balancing of capacities between the individual conveying means and bunker systems, and/or controls the extraction output while taking the conveying capacity of the downstream conveying means and buffer capacity of the bunker systems into consideration.

Procédé de commande du transport d'évacuation des minerais abattus par des machines d'abattage travaillant en divers endroits des excavations en exploitation minière souterraine, à l'aide de moyens de transport et de trémies disposé(e)s dans les excavations souterraines. Selon ce procédé : sur la base de données réelles enregistrées en continu, on détermine les capacités minimales disponibles de transport des moyens de transport et de tampon des trémies; dans une unité de commande assistée par ordinateur, ces capacités sont comparées au débit d'abattage réel actuel et/ou au débit d'abattage de consigne attendue pour une période prédéfinie, et/ou au débit planifié extrapolé d'après les données réelles antérieures; si des écarts sont constatés, l'unité de commande produit automatiquement une compensation de capacité entre les différents moyens de transport et trémies, et/ou commande le débit d'abattage en tenant compte de la capacité de transport des moyens de transport placés en aval et de la capacité de tampon des trémies.
