Abstract

L'invention concerne un procédé et un appareil de contrôle du mouvement d'un convoyeur de front de taille Ledit appareil comporte une source primaire montée dans une galerie et un signal optique émis par la source réfléchie par un réflecteur placé sur le convoyeur pour être renvoyé à un récepteur situé à proximité de la source. Un circuit de traitement détermine un mouvement angulaire du convoyeur. Un dispositif optique ou transistor à corde détecte la distance entre la source et le convoyeur. Le circuit de traitement peut déterminer le mouvement du convoyeur d'après les mesures d'angles et de distances. Application aux systèmes d'abattage de charbon au long front de taille.The invention relates to a method and an apparatus for controlling the movement of a face conveyor. Said apparatus comprises a primary source mounted in a gallery and an optical signal emitted by the source reflected by a reflector placed on the conveyor to be returned. to a receiver located near the source. A processing circuit determines an angular movement of the conveyor. An optical device or string transistor detects the distance between the source and the conveyor. The processing circuit can determine the movement of the conveyor from the measurements of angles and distances. Application to coal felling systems with a long face.
