Sub Level Stoping by JOSE CIFUENTES ORELLANA on Prezi Next

Book Description. The first comprehensive work on one of the most important underground mining methods worldwide, Geotechnical Design for Sublevel Open Stoping presents topics according to the conventional sublevel stoping process used by most mining houses, in which a sublevel stoping geometry is chosen for a particular mining method, equipment availability, and work force experience.

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).

This paper describes several sources of external dilution affecting the stope walls during underground sub-level and bench stoping. Factors which control ground behaviour such as the geometry of the openings, the influence of geological discontinuities, stress re-distribution and blasting practices are discussed. Crown stope instability due to stress concentrations induced by changes in the ...

Mining - Mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

Sublevel stoping

Sublevel stoping generally is a large-scale open stoping method. It sometimes is referred to as long-hole or blasthole stoping. This method usually is applied to strong ore bodies that require minimal support and are surrounded by strong country rock. The ore body should be …

Definition of sublevel stoping. i. In this mining method, the ore is excavated in open stopes, retreating from one end of the stope toward the other. The orebody is developed first by a series of sublevel drifts above the main haulage level. The sublevels are connected by a starting raise at one end of the stope and by a passageway raise for ...

Longitudinal longhole retreat

In sub-level stoping, the holes are generally just a few meters apart and some of the holes are adjacent to both the foot wall and the hanging wall. If deviation occurs, it causes a decrease in ore recovery, an increased amount of dilution, and less homogenous fragmentation. In the …

Sublevel Caving Safety. Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally 5mx3.7m sublevel nature of drifts aids in the safety of this mining method.

Sublevel caving

Transverse Longhole Stoping is a popular large scale underground mining method known for its ability to simplify stope sequencing. It is an open stoping method and is very similar to sub-level open stoping, Longitudinal longhole retreat, and blast hole stoping.

PDF Sublevel Stoping at a large underground quarry the

In sublevel stoping (fig. 86) the ore is blasted out into an open stope and falls into funneled raises or mill holes, and no handling is needed except where benching down is done in two or more steps, when some shoveling may be necessary to clean off the lower benches. With block-caving, most of the ore broken in undercutting falls by gravity ...
