Open pit mining Open pit mining where material is excavated from an open pit is one of the most common forms of mining for strategic minerals This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations which increases the amount of ore needed to be minedRill Cut Stoping Mining Rill cut or rill stoping as shown at B Fig 2 has the principal advantage that when filling is used it can be run down through a raise at the apex of the stope and will fill the stope without shoveling Its disadvantages on the other hand are as follows
