ABSTRACT:
In an apparatus for installing resin anchored roof bolts in a mine roof, continuous bolt material is stored on a spool rotatably mounted on a mobile roof bolter frame. As the apparatus advances along the mine passageway, the bolt material is uncoiled from the spool and guided upwardly into spaced apart, resin filled holes that are preformed in the mine roof. The bolt material is severed just beneath the roof at each hole to form a unitary roof bolt. A stop is formed in the unitary bolt with a hydraulically operated head and mandrel mechanism that makes a right angle bend in the bolt just beneath the mine roof.
