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).

Stoping - Wikipedia

Sublevel stoping is not dependent on the width of the ore body. Widths of less than 6 m (20 ft), however, make the utilization of long-hole drilling techniques more difficult. The main criteria for sublevel open stoping are competent ore and stable host rock, regular ore boundaries, and a footwall dip that exceeds the angle of repose of broken ore.

Shrinkage mining was a common stoping method prior to mechanised mining and the introduction of hydraulic fill. Sub-level stoping, cut and fill mining and sub-level caving have generally replaced shrinkage mining in Australia, Europe and Canada. The method is still used in a handful of non-mechanised mines in South America, Africa, Asia and Canada.
