This type of mining is performed when the gold ore is on the side of a mountain. Drift mining is a process of accessing alluvial deposits by cutting into the side of the earth, rather than tunneling directly downwards. The opening to the mine will be dug slightly lower than a rock or mineral vein whenever possible. The tunnels that are excavated are horizontal and are known as drifts.
Drift mines have flat entries into the paystreak from a hillside. Drift mining poses a higher economical means of recovery than other more invasive types of underground mining that entail digging up through rock. Once tunnels are driven, they may be utilized for haulage, ventilation, and exploration of further possible gold seams. Material is normally mined and taken out using longwall mining or room and pillar mining methods and nonstop mining equipment. Drift mines are a general type of mine used all throughout the world.
This mining process was in fact risky in earlier years. Several tunnels caved in trapping and slaughtering miners. Gold ore was the material which was frequently mined in this manner. In the beginning, miners were annoyed when they had to separate the silver, copper, and other minerals that they discovered along with gold that they were looking for.
