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).

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.

Figure 8.3.9 Sublevel stoping (blasthole method) using ring drilling and blasting into a slot Source: after Hamrin, 1982 The vertical spacing between sublevels is limited by the accuracy of the ring drills. As with the innovation of VCR, the accuracy of DTH drilling technology led to a variant of sublevel stoping

2011-5-1 This paper discusses the stope parameters of the sublevel subsequent filling stage in Daye Iron Shizishan section. According to the similar material simulation technology, which is the main means, displacement monitoring and internal stress monitoring, several conclusions are summarized as bellow: When the parameter of the room and pillar is 18m, the underground mining is safe and steady.

2017-3-30 Sublevel stoping, sublevel caving, top-slicing, and block-caving require more stope preparation before ore extraction can begin. In sublevel stoping (a form of open stoping), ore chutes, manway, and “starting raises” must be put up and one or more drifts driven on each sublevel (fig. 60, B).

8.3.3: Sublevel (Open) Stoping. If we had a stronger and more competent host rock, we could dispense with the need to keep ore in the stope to support the hanging wall as we do VCR mining. Indeed, such deposits do exist, and when they do, we can employ the open stoping method.

Sublevel stoping mining methods are generally employed to extract steeply dipping tabular ore deposits characterized by relatively long strikes and having various thicknesses. Ore is recovered from each sublevel in a planned sequence of primary and secondary stopes with delayed backfill in a manner to create a stress shadow to avoid high stress ...
