The invention provides a mining machine (10) and a method of mining. The mining machine (10) includes a body (12), an arm (14) mounted on the body (12) for angular displacement relative to the body (12), a mining head (16) mounted on an end region (14,1 ) of the arm (14) for rotation relative to the end region (14,1 ) of the arm (14), drive means (18) for driving the mining head (16) to rotate relative to the end region (14,1 ) of the arm (14) while the mining head (16) is in abutment with a mining face, and drive means (18) for driving the arm (14) to displace angularly relative to the body (12), such that, in use, the arm (14) can be driven to displace angularly relative to the body (12) to sweep the mining head (16) across a mining face while the mining head (16) is driven to rotate and in abutment with the mining face, thereby to mine the mining face.

L'invention concerne une haveuse (10) et un procédé dabattage. La haveuse (10) comprend un corps (12), un bras (14) monté sur le corps (12) en vue dun déplacement angulaire par rapport au corps (12), une tête dabattage (16) montée sur une région dextrémité (14, 1) du bras (14) de façon à tourner par rapport à la région dextrémité (14, 1) du bras (14), un moyen dentraînement (18) servant à entraîner la tête dabattage (16) en rotation par rapport à la région dextrémité (14, 1) du bras (14) pendant que la tête dabattage (16) est en appui contre un front dabattage, et un moyen dentraînement (18) servant à entraîner le bras (14) en déplacement angulaire par rapport au corps (12) de telle sorte quen cours dutilisation, le bras (14) puisse être entraîné en déplacement angulaire par rapport au corps (12) pour balayer avec la tête dabattage (16) létendue dun front dabattage pendant que la tête dabattage (16) est entraînée en rotation et se trouve en appui contre le front dabattage, afin dexploiter ainsi le front dabattage.
