Cutting is where soil or rock material from a hill or mountain is cut out to make way for a canal, road or railway line.
Cutting in construction is mechanically excavated or blasted out with carefully placed explosives. The cut may only be on one side of a slope, or directly through the middle or top of a mountain. Generally, a cut is open at the top (otherwise it is a tunnel). Cuts can be created by multiple passes of a grader, scraper or excavator, or by blasting.
Material removed from cuts is ideally balanced by material needed for filling along the same route, but this is not always the case when cut material is unsuitable for use as filling. The material is then transported using heavy machineries such as trucks, long boom and long reach excavators (Caterpillar, Hitachi, and Komatsu).
Different hydraulic carriers of all sizes can be attached to excavators and preform several rock cutting and mountain cutting such as:
