2021-3-1 · The DLSOS stoping method is an adapted sublevel open stoping method with backfill. In this method, the stoping sequence is from bottom-up, and therefore, the blasted ore is mucked under the protection of the upper stope pillar. The muck is not affected by the weight of overlying strata, and the stress is not transferred.

2010-8-3 · 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.

SubLevel Stoping - Introduction to 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).

Considerations for Sublevel Open Stoping - OneMine

Sublevel stoping generally is a large-scale open stoping method. It sometimes is referred to as long-hole or blasthole stoping. This method usually is applied to strong ore bodies that require minimal support and are surrounded by strong country rock. The ore body should be fairly regular in shape and well-defined.

2017-8-4 · 1. Overview Avoca Method of mining is a variation of sublevel stoping method with the introduction of waste rockfill as backfill. This method is popular in high grade epithermal vein deposits where the strength and conditions of the walls of the open stopes are weak to moderate and require backfilling of waste rock to stabilise the walls, minimise the ore dilution and maximise the ore recovery.

Shrinkage stoping - QueensMineDesignWiki

2019-6-28 · Author: Mike Neumann, Neumann Engineering and Mining Services Inc. (NEMS) Date: May 2010 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.
