Raise boring is a drilling technique used to create shafts in hydropower, infrastructure & tunnel / mining industry, where you first drill a smaller hole (pilot drilling) between two existing levels, and then we mount a reamer down at the breaktrough site, after that you pull the reamer up through the rock to create the shaft.
