ABSTRACT:
The mine support system (26) is typically used in underground coal mines. Support for the hanging wall (40) of the mine is provided by elongate, transversely extending headboards (10) which are supported by spaced apart supports. The supports may take the form of upright mine supports, typically timber props (28) located on the footwall (34) of the mine working, by roof bolts (30) engaging the hanging wall, or by a combination of props and roof bolts. Prestressing grout bags (32) are located on the headboards and bear against the hanging wall. The combination of headboards and bags forms a continuous bridge between the props.
