Sublevel caving also allows for a slightly more selective extraction of the orebody than is attainable through block or panel caving. Production rates achieved in sublevel caving operations are typically lower than for block caves but higher than for stoping methods." CAVING requIremeNts Caving is a nonselective, bulk mining method.
Sublevel stoping generally is a largescale open stoping method. It sometimes is referred to as longhole 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 fairly regular in shape and welldefined.

A mining method involving overhand, underhand, and shrinkage stoping. Its characteristic feature is the use of sublevels. The sublevels are worked simultaneously, the lowest on a given block being farthest advanced and the subs above following one another at short intervals. The uppermost sublevel underneath the cover is partly caved.
Celebrating MEC Mining''s recent expansion into underground hard rock mining services, our next webinar will focus on the effective application of sublevel open stope mining. MEC Mining''s Principal Mining Engineer Alessandro Dotta will discuss: the geological and geotechnical selection criteria for sublevel open stope mining and variations ...
A sublevel stoping mining method is predominantly employed and the ore is trucked to surface using a variety of articulated dump trucks. Oneway haul distances are of the order of and the cycle time for trucking is typically 45 min. Adaptations of this mining method as well as room and pillar mining are undertaken depending on the ...
SubLevel Caving Subsidence reaches surface at the Ridgeway underground mine. Using this method, mining is planned to extract rock from the stopes without filling the voids; this allows the wall rocks to cave in to the extracted stope after all the ore has been removed. The stope is then sealed to .
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 Canada.
Apr 01, 2014· 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 .
Table of ContentsStopingStopeDevelopment MethodsRaisst of Driving Raises Stoping The foregoing discussion relates to general mine development and covers the work required to reach and penetrate the ore bodies and to provide the main arteries through which the ore is taken from the mine. These arteries provide mine drainage and avenues for travel and transportation of .
This paper describes several sources of external dilution affecting the stope walls during underground sublevel and bench stoping. Factors which control ground behaviour such as the geometry of the openings, the influence of geological discontinuities, stress redistribution and blasting practices are discussed. Crown stope instability due to stress concentrations induced by changes in the ...
Stoping, in mining engineering, the opening of large underground rooms, or stopes, by the excavation of is practiced in underground mineral mining when the surrounding rock is strong enough to permit the drilling, blasting, and removal of ore without mines where the rock requires no artificial support, the operation is known as open stoping.

Sublevel Open Stopping In this mining technique, a series of horizontal tunnels, or sublevels, are excavated one above the other, to access different levels of a vertical ore deposit. At the bottom of the stope is a haulage tunnel, which is used to transport ore that collects at the bottom.
