    8.3.3: Sublevel (Open) Stoping. If we had a stronger and more competent host rock, we could dispense with the need to keep ore in the stope to support the hanging wall as we do VCR mining. Indeed, such deposits do exist, and when they do, we can employ the open stoping method.

    The fill is a mix of sand and water, about 65% of which is solid matter. By mixing cement into the last pour, the fill's surface will harden into a smooth roadbed for rubber-tyred equipment. Backfilling is also used with sublevel stoping and VCR mining, with crushed rock introduced as a complement to sand fill.

  • Sublevel Stoping in Small Mines

    It can be used with dips that are too flat for successful shrinkage stopes and can be modified for use with slushers on dips below about 40°. Initial mining at the Copper Canyon operation consisted of sublevel stopes for the wider ore sections and shrinkage stopes for the narrow sections where ore widths averaged about 15 ft.

  • Backfill Practices for Sublevel Stoping System | SpringerLink

    Thus, backfilling is one of the most critical tasks for sublevel stoping mining systems with delayed backfill. The selection of the type of backfill is a substantial component of backfill design at preliminary stage of mining production. This paper presents a review of backfill practices with emphasis on backfill operations in North America.

  • Underground Mining Methods - Mining Matters

    Sublevel caving is usually carried out when mining of the ore body through an open pit method is no longer economically feasible. 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.
