Abstract:
A roof bolting apparatus adapted for mounting on a longwall face conveyor track of a longwall mining apparatus that is substantially parallel to a mining face; comprising:a platform extending along an axis and having a drive mechanism that is adapted to cooperate with the longwall mining apparatus for propelling the platform along the longwall face conveyor track;a slide plate mounted on the platform for movement in a direction perpendicular the axis of the platform, the slide plate having a front edge substantially adjacent to the mining face when the platform is installed on the longwall face conveyor track; anda roof drilling assembly mounted on the slide plate to extend over the front edge for rotation about a first axis perpendicular to the axis of the platform from a first position in which the roof drilling assembly is substantially parallel to the axis of the platform to a second position in which the roof drilling assembly is substantially perpendicular to the axis of the platform.
