Abstract
A modular roof bolting apparatus adapted to be installed on a face conveyor track of longwall mining equipment. A roof drilling assembly is rotationally mounted on a platform to an operating position and an installation position. The roof bolting drill is mounted to the platform so that in the lowered position the roof bolting drill lies parallel to an elongate axis of the platform. This arrangement provides a low-profile arrangement that allows the roof bolting apparatus to be installed in areas where space is limited. For example, the roof bolting apparatus can be lifted over either the headgate or tailgate drive without having to disassemble them.
