Underground Mining Methods - Mining Matters

2021-8-18  Mining now proceeds underground, underneath the open pit. At first, both a raise and a network of tunnels are made. At different sublevels, jumbos are used for long hole drilling, drilling directly upwards into the roof. These holes are then charged with explosives and blasted. As the roofs cave in, the rock from the ground surface will cave in ...
