Norwegian cut

A variation of the ordinary cut that may be said to represent a combination of the latter and the fan cut. The first drill holes are formed with a sharper angle toward the working face, which facilitates breaking. This type of cut has been employed successfully in headings of small section, the cut hole being blasted first, followed by the bench holes. In order to obtain the maximum possible advance the cut may also be deepened after blasting, during the first pause in working, e.g, the whole section then being broken out simultaneously.
