The raisebore mining method is an underground mining method to obtain ore, in which a horizontal underground shaft is built below the deposit. A revolving drill called a "reaming head" is input vertically into the deposit which knocks the ore loose and allows it to fall into the collecting vehicle below. This process is used for several mined resources, including uranium. When uranium is mined using this method, fluid is added to turn it into a liquid slurry in order to pump it up to the surface.
The video below (from Cameco, a uranium mining company) shows the process involved in the raisebore mining method for uranium.
