Abstract: A mine roof support anchor and process for installing the same. The anchor comprises a pair of wedge members, each of which has tapered surfaces adapted for interengagement to effect expansion of the shell into gripping engagement with the mine roof. The wedge members are joined by a connector at one end thereof. Upon threading the roof bolt through one wedge member, the upper end of the bolt engages the connector, thereby effecting upper movement of the other wedge member and downward movement of the one wedge member, causing rapid expansion of the shell. External ribs on one of the wedge members engage the mine roof after partial expansion of the shell to limit upward movement of the wedge member. A vertical rib on the wedge member through which the roof bolt is threaded prevents rotation thereof during the rotation of the bolt through the anchor.
