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:
“Angel of hope and calendars, do you know despair?
That hole I crawl into with a box of Kleenex....”
—Anne Sexton (1928–1974)
“Come, gentle night, come, loving, black-browed night.
Give me my Romeo, and when I shall die,
Take him and cut him out in little stars
And he will make the face of heaven so fine
That all the world will be in love with night,
And pay no worship to the garish sun.”
—William Shakespeare (1564–1616)
