Abstract
A mine roof support system is disclosed having a connector. The connector has a first hole through which one end of a first roof supporting rod is inserted and a second hole through which one end of a second roof supporting rod is inserted. The first and second roof supporting rods are fastened to the connector so as to support the roof of the mine. In order to increase the bending arcs of the connector along which the first and second roof supporting rods bend without increasing the weight of the connector, the holes of the connector may be bevelled to form elliptical openings in the connector and the connector may be canted.
