  • Mining system and method featuring a bread loaf shaped borehole
    Patent number: 6612655
    Abstract: A method and apparatus for cutting a borehole substantially in the shape of a bread loaf within a mine includes four cutting systems. The first cutting system is a pair of three-armed, counter rotating, cutting heads which remove material from the mine face in a substantially vertical plane. The second cutting system is a pair of rotating cutting drums which follow the pair of counter rotating cutting heads. The third cutting system is a substantially vertical, rotating cutting head which removes the kerf formed at the ceiling or roof portion of the borehole. The fourth cutting system is a plow which both removes the kerf at the bottom of the borehole and directs the mined material to a conveyor system to remove the mined material from the mine.
