limestone underground quarry sub level stoping Shrinkage mining was a common stoping method prior to mechanised mining and the introduction of hydraulic fill. Sublevel stoping, cut and fill mining and sublevel caving have generally replaced shrinkage mining in Australia, Europe and Canada. The method is still used in a handful of nonmechanised mines in South America, Africa, Asia and
The quarry has been in operation since 1927; at present, exploitation is carried out underground via the sublevel stoping method. Exploitation involves two levels, with 5 rooms on the upper level and 9 rooms on the lower level. After analysing data obtained from laboratory and in situ tests carried out on rock samples and natural discontinuities, the geomechanical properties of the medium
