Jan 09, 2018 Miners extract garnets in a number of ways. In open pit mining, workers remove the soil from an area, and then chip the rock out of the ground by hand or with machinery. This method can damage agricultural areas, so miners developed another method in which they dig vertical shafts into the ground, supported by timbers.
