Sublevel Shrinkage (SLSh) Mining—A State-of-the-art

Sublevel shrinkage (SLSh) is an underground mining method similar to sublevel caving (SLC) but with continuous backfilling from the top. It features a top-down mining sequence with production drifts 2. Characteristics. (1) Caving mining method no longer divides the ore block into ore rooms and pillars, but takes the whole ore block as a stoping unit, and carries out continuous single-step stoping Caving Mining Method Classification and

Sublevel Caving Method Without Sill Pillar SpringerLink

Sublevel Caving Method Without Sill Pillar. It is the mining process in which a level is divided into several sublevels and the stopping of ore is performed by sublevel caving from top to bottom. The lower part of a sublevel does not have the bottom structure comprised of the special-purpose ore-drawing drifts.The mining projects undertook by Xinhai Mining spread around the world, covering gold mining, iron mining, copper mining over 70 kinds of And the mining methods were shrinkage method and sublevel drilling and stope mining method.

Mathematical Programming Application in Sublevel Caving

Mining operations start at the uppermost sublevel and proceed sequentially down-wards. In each sublevel, the in-situ ore is drilled in a fan-shaped design along the produc-tion drift at a constant horizontal distance, called burden. Then, the ore is blasted, slice by slice, from the hanging wall to the footwall in a retreating manner [7].Based on the engineering background of the Meishan iron mine with sublevel caving (SLC) method, in this work, we adopted the method for identifying the shape of mined orebody (the original location in blasted slice), which analyzed and determined reasonable stope structure parameters. In the field test, the markers were Optimization of Stope Structure Parameters Based on the
