Notching

 

(in mining), the process of making a cut in a mineral (coal, rock salt, and so on). Supplementary free surfaces are notched in the seam to be worked to facilitate breaking-out. Until the early 20th century, notching was done mainly by hand by miners and was one of the most laborious processes; notching is now performed by cutting machines.
