The quarry has been in operation since 1927; at present, exploitation is carried out underground via the sub-level stoping method. Exploitation involves two levels, with 5 rooms on the upper level and 9 rooms on the lower level.
The aim of this study was to evaluate the state of stress of a „voids-pillar" structure excavated by means of the sub-level stoping method in an underground limestone quarry near Bergamo (Italy). Both the current structure of the quarry (i.e. the

Abstract: Goldex is a sublevel open stoping mine near Val-d'Or in northwestern Quebec. The orebody will be extracted in stages, using a novel mining method, resulting in a single stope with the dimensions of 450 m on strike, 250 m in height and up to a width of 120 m. limestone underground quarry sub level stoping.
A single lift design is the most basic arrangement for a sublevel stope extraction. The stope shape and size is constrained by two sublevels; the extraction and the drilling horizons. Access to the stope is via cross-cuts off a permanent access drive parallel to the. FIG 12 - Holes toeing into the stope boundaries.
