Methods of Underground Mining — Bit Service

Shrinkage stoping is similar to the cut and fill method, except instead of filling each level to act as a support, the blasted, broken ore is left in the resulting space to act as a support for the next level. After all the levels are blasted, the ore is then removed. This underground mining method is a good option for steep ore bodies.

Description of mining methods (step by step)

The mechanized cut-and-fill stoping was selected to meet the following factors: gently dipping; proper selectivity; poor quality of the hanging wall; narrowness of the zone; relatively short and irregular strike length.

Backfilling Mining Stopes

In cut-and-fill stoping its function is to support the walls and to provide a working floor; loose filling cannot be packed tight enough against the back to hold great downward pressure and under subsidence of the back it is compressible.
