Sublevel Stoping in Small Mines

Nov 07, 2020· Stoping is started at the end of the block opposite the service raise by excavating a slot across the stope over the first finger raises and extending upward to the top sublevel. At first our mining slots were narrow, transverse shrinkage stopes with access from the sublevels. As we gained experience, the slots were started by driving a series

Assisted geotechnical design for sublevel open stoping

Abstract The prediction of rock mass stability in sublevel open stope (SLOS) mining is performed in the design of open stopes to estimate the stope size required to reduce operational hazards and achieve continuous production. For almost four decades, the Stability Graph method has been used for this purpose. Several improvements of the Stability Graph method have taken place through the s.

SubLevel Stoping Introduction to Sublevel Stoping

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). Longholes can be inclined in any direction, but the ring or pattern usually forms a plane, and the holes
