Constructing Ventilation Bulkheads With Shotcreted Wire Panel.
MISSING :24 pages
This Bureau of Mines report describes laboratory and field experimentation in building mine ventilation stoppings, air-door frames, and fan bulkheads with a civil construction technique. Shotcrete is applied to a free-standing, three-dimensional wire- truss panel, which is easily cut and rapidly erected. In mines where shotcrete eqiupment is available, this technique should be faster and cheaper than conventional block-and-mortar or monolithic concrete construction.
