Crosscut(redirected from crosscutting)
Also found in: Dictionary, Thesaurus, Legal.
horizontal (sometimes inclined) underground mine working that has no direct outlet to the surface and is driven into the rock at an angle to the line of strike of the deposit (that is, it approaches or intersects the bed). Crosscuts are intended for stripping minerals, for transporting goods and personnel (for which rails are laid and conveyors are mounted), and for ventilation and water drainage.
an underground auxiliary working formed from the side of inclination (dip) of a seam during excavation of the main working by the broad-cut method. Crosscuts are built parallel to the main working and are used for the disposal of rock resulting from cutting and for ventilation.
in mining, a horizontal underground mine working that does not have a direct outlet to the surface and runs in the direction of the roof or floor of a seam of useful mineral or from the roof to the floor.
(1) An underground mining excavation driven between two mine shafts or tunnels when a deposit of a useful mineral is opened.
(2) The term given to operations designed to join two underground mining excavations with each other or to connect an excavation with the surface. Crosscut operations may involve driving from two faces, driving from a single face, or consecutive driving.
