Stoping Mining Methods

Stoping Mining Methods

 · It may be used successfully in weaker ground than could be worked safely by other openstope systems, as the miners are always protected by solid ground overhead. Large open stopes are mined by this method where the ore is so soft that it can be drilled with auger steel, and the method can be applied where the ore is too weak to be safely minable by shrinkage stoping.

mining mining Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

What Is a Box Cut? (with picture)

In basic strip or surface mining, workers start by using a dragline excavator to create a box cut along the length of the earth and rocks removed from this cut are set aside above ground for later reuse. Workers then enter the trench created by the box cut and mine all available minerals and ore. Once the trench has been stripped, the soil and rocks are used to refill the box cut.
