Box Cut

A box cut is a small open cut created to provide a secure and safe portal as access to a decline to an underground mine. Generally the box cut is sunk until sufficiently unweathered rock is found to permit the development of the decline. The portal is generally made safe with rock bolts, wire mesh, and shotcrete, which prevents accidental rock falls from closing access to the decline.

Famous quotes containing the words box and/or cut:

    It all ended with the circuslike whump of a monstrous box on the ear with which I knocked down the traitress who rolled up in a ball where she had collapsed, her eyes glistening at me through her spread fingers—all in all quite flattered, I think. Automatically, I searched for something to throw at her, saw the china sugar bowl I had given her for Easter, took the thing under my arm and went out, slamming the door.
    Vladimir Nabokov (1899–1977)

    You realize the futility of worry. You learn to hate the small and the little. Life is a pie which you cut in large slices, not grudgingly, not sparingly. You know your limitations and proceed to eliminate them; your abilities, and proceed to develop them. You are free.
    Alice Foote MacDougall (1867–1945)
