Raiseborrning är en schaktfri borrmetod som inleds med att ett pilothål borras längs ledningslinjen; t.ex med hammarborrning eller styrd borrning. Därefter byts borrhuvudet ut mot ett upprymningshuvud med hårdmetallrullar. Upprymningshuvudet har samma diameter som det färdiga hålet ska ha.

Raise boring is used to drill shafts for ventilation, transferring ore from one level to another, creating silos for storing rock as well as hoisting of rock and ore to the surface. The application of Raise boring in mining also assists in providing access for personnel or material underground.
