Boliden Silver Mine, Garpenberg, Sweden - Mining
“In 2006, Garpenberg started rill mining, and prepared much of the Lappberget orebody for sublevel stoping.” Garpenberg has remained a shaft hoisting operation. The new Gruvsjö shaft has a 4.5t-capacity ABB single-drum production hoist, while the North mine added a ramp access below the shafts in 1986.

comprised: (i) field monitoring in three mines, using cut-and-fill mining, rill mining (or Avoca method) and sublevel caving; (ii) seismic loading of rock support by blasting experiments in the Kiirunavaara Mine; and (iii) numerical analyses of different phenomena and failure mechanisms. This paper is a short summary of these research activities.

2017-2-7 · The main mining method is known as sublevel stoping. This means that the ore is mined in layers between two drifts (tunnels), which are driven through the ore body. Other mining methods include cut-and-fill mining, rill mining and residual mining of sill pillars. Drilling In the case of sublevel stoping, holes for the

2017-4-5 · Sublevel caving lacks the flexibility of supported-stope methods but is more flexible than block caving. The sublevel development serves to explore the ore body at each caving horizon before mining begins, and irregular boundaries can be followed more easily than with block caving and with less dilution from the walls.

The emulsion is mixed mechanically when charging. During sublevel stoping, a normal round produces approximately 10,000–20,000 tonnes of loose ore. Loading ore from the sublevel stoping area takes place using remote-controlled LHD loaders. Loading when drifting and cut-and-fill mining is performed with a wheel loader.
