发明名称 Mine roof support system
摘要 The present invention relates to a cable truss system for supporting a mine roof. The system includes at least one cable bolt secured in at least a pair of spaced boreholes. A leading end of each cable bolt is secured within the borehole and the trailing end extending out of the borehole. At least one splice tube is coupled to the trailing end of each cable bolt. Each splice tube includes an elongated conduit between a pair of spaced ends with the conduit adapted to receive at least a pair of cables therethrough. Cable attachments are provided on the trailing end of each cable bolt at a position on the cable bolt such that the splice tube is positioned between the cable attachment and the borehole. The cable attachment has a diameter larger than the inner dimensions of the conduit of the splice tube such that the cable attachment is adapted to abut against one end of the conduit of the splice tube.
