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:

    I walked on the banks of the tincan banana dock and sat down under the huge shade of a Southern Pacific locomotive to look at the sunset over the box house hills and cry.
    Allen Ginsberg (b. 1926)

    Then cut down the trees when lumber grown,
    And there’s your pristine earth all freed
    From lovely blooming but wasteful weed
    And ready again for the grass to own.
    Robert Frost (1874–1963)
