crosscut

[′krȯs‚kət]
(engineering)
A cut made through wood across the grain.
(mining engineering)
A small passageway driven at right angles to the main entry of a mine to connect it with a parallel entry of air course.
A passageway in a mine that cuts across the geological structure.

Crosscut

 

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.


Crosscut

 

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.


Crosscut

 

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.


Crosscut

 

(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.
