When mineral reserves are found far below the Earth’s crustal surface, underground mining is used. Because it involves greater safety precautions, underground mining necessitates far more planning than surface mining.
In order to make room for tunnels, it entails drilling explosive-filled holes into the earth. To stop future harm to the surroundings, the tunnels are filled with concrete once they have been built.
The miners then pierce the rock using tools like drill rigs to extract the mineral after creating the tunnels. The extracted ore needs to be moved from the mine after extraction. Either a railway or a truck is used for this.
