  • Mining shield support apparatus
    Patent number: 4048803
    Abstract: The invention concerns an advanceable shield support assembly for longwall mining. The assembly has a pivotable main roof cap housing a retractable and extensible auxiliary roof cap. Normally the main roof cap supports the roof and the auxiliary one is retracted. However, before the assembly is advanced, the auxiliary roof cap is extended to support the roof section between the working face and the front edge of the main roof cap. The movement of the auxiliary roof cap, and the force with which it engages the roof section, are controlled by cooperating guide tracks and track-engaging elements capable of exerting a wedging action.
