Keeping up with caving - REDPATH MINING

Sub-level caving is typically used where the orebody has a smaller footprint and/ or more competent rock mass that prevents the continuous caving required for a block cave. Blasting of the entire orebody is required to produce a production ore flow. As sub-level caving uses a ‘top down’ approach, it requires less upfront capital

Abstract: The Telfer Underground Sublevel Cave (SLC) Operation is located approximately 800 m below the west wall of the Main Dome Open Pit. The Telfer SLC initiated in late 2006 and is caving successfully at a global rate of approximately 0.6 m per day. The cave is expected to break into the planned 5384 mRL bench on the west wall of the active main dome pit which has a haul ramp running ...

excavated using induced caving, hence the name sublevel caving (Cokayne, 1982). The present system of sublevel caving is highly mechanised; the ore is completely drilled and then blasted. The mine design and layout have evolved from small scale rings with sublevel intervals of 9m to large scale rings with sublevel intervals of up to 29m

Sub-level caving. This method owes the first part of its name to the fact that work is carried out on intermediate levels (that is, sub-levels) between the main production levels. It follows the same basic principles as the block caving mining method, but the caves are smaller in size and not as long lasting.

This method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent. The production for a mine using sublevel stoping can range from 15- 40 tons/employee-shift, while one stope can produce greater than 25000 tons per month.

The role of block caving Although the caving mining system was initially used for shallow orebodies, it has recently been applied at depths of 2km underground. According to Suorineni, “caving heights have also increased drastically from about 200m to 500m”, creating so-called ‘super caves’.“There is insufficient experience caving in these environments,” he adds, which is a ...

8.4.2a Block Caving. This method, which was developed in the U.S. after WW I, is well suited for mining in weak orebodies. Panels or blocks of ore are undercut. Once undercut, the weak orebody begins to cave under its own weight. The caved ore is drawn off through draw points.
