Title
(EN) MINING MACHINE AND MINING METHOD
(FR) ABATTEUSE ET PROCEDE D'EXPLOITATION MINIERE
Abstract
(EN)
A mining machine (20) for combined entry and retreat cutting of material located in underground seams including, a movable mainframe (21), a wing (50, 51) extending ahead of the movable mainframe, a cutter assembly (100) positionable proximate the end of said wing for entry cutting a hole in the material when the wing is aligned with the direction of movement of the mainframe, a pivotal connection (130) between the mainframe and the wing for orienting the wing at an angle to the direction of the movement of the mainframe, and a carriage mechanism (80) for moving the cutter assembly along the wing for cutting of the material in proximity to the wing during retreat cutting of the material.
(FR)
La présente invention concerne une abatteuse (20) convenant à l'abattage de roche en attaque aussi bien qu'en retrait dans une veine minière. Cette abatteuse comporte notamment un châssis mobile (21), un bras (50, 51) en projection sur l'avant du châssis mobile, et une tête d'abattage (100). Pour forer un trou dans la roche par abattage en attaque, lorsque le bras se trouve dans l'axe de déplacement du châssis, on amène la tête d'abattage à l'extrémité de bras. Une liaison pivotante (130) entre le châssis et le bras permet d'orienter angulairement le bras selon l'axe de déplacement du châssis. Enfin, pour tailler la roche par abattage en retrait à proximité du bras, un chariot (80) assure le déplacement de la tête de coupe le long du bras.
