  • Shrinkage stoping

    2019-6-28 · Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore. It is an overhand mining method that relies on broken ore being left in the stope to be used as the "working floor" and to support the walls. During the mining cycle, only 30 – 35% of the ore blasted is extracted being ...

The mine uses four different mining methods: sublevel open stoping in zones A and B; drift and fill mining in zone C; narrow vein mining in zone C; Alimak mining in zones A and B. This paper focuses on the sublevel open stoping mining used in zone A. In this method, top and bottom accesses are mined to reach the sublevel open stope.

  • Mining Stope Development Method

    2017-3-30 · Sublevel stoping, sublevel caving, top-slicing, and block-caving require more stope preparation before ore extraction can begin. In sublevel stoping (a form of open stoping), ore chutes, manway, and "starting raises" must be put up and one or more drifts driven on each sublevel (fig. 60, B).

  • SubLevel Stoping

    INTRODUCTION The sublevel stoping mining method is usually applied to a relatively steeply dipping, competent ore body, surrounded by competent wall rock. Ore is produced by drilling and blasting longholes, which can range from 50 mm (2 in.) to 200 mm (7% in.) diam, with lengths up to 90 m (300 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.

  • Techniques in Underground Mining

    2021-12-11 · This allows the procedures to move continuously from one sublevel to another, allowing for the most efficient use of work crews and equipment. In effect the mine is analogous to a departmentalized factory. Sublevel mining, however, being less selective than other methods, does not yield particularly efficient extraction rates.

  • Considerations for Sublevel Open Stoping

    Sublevel stoping is not dependent on the width of the ore body. Widths of less than 6 m (20 ft), however, make the utilization of long-hole drilling techniques more difficult. The main criteria for sublevel open stoping are competent ore and stable host rock, regular ore boundaries, and a footwall dip that exceeds the angle of repose of broken ore.

  • Sublevel Caving

    2016-9-19 · Sublevel Caving. In this method, the stope is divided into sublevels, fairly close to each other, normally with 8-15m vertical interval between each two adjacent ones. These sublevels are called sublevel drifts or production drifts. Production is carried out from the sublevel drifts by means of long holes above the end of the production drifts.
