8.4.2a Block Caving | GEOG 000
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. As the ore is drawn off, the orebody will continue to cave under its own weight. This process will continue until all of the orebody within the block or panel has been recovered.

Ground Response and Mining-Induced Stress in Longwall Panel …
Xie et al. investigated mining-induced stress distribution in the longwall panel of a kilometer-deep coal mine with borehole stress monitoring method [7]. The results indicated that the influence ...
Longwall Mining
The longwall-mining method is a continuous mining system that was developed for mining coal deposits uniform in thickness and slope or where the overburden pressures may crush support pillars or for improving productivity. This method relies on the complete extraction of the coal in a designated area referred to as a panel (of solid coal).
An Investigation on Optimal and Safe Design of Highwall Mining Panel …
However, designing highwall mining panels becomes challenging in cases where there is a presence of jointed rock mass in the overlying overburden strata, making it difficult to rely on available empirical formulas. In this study, a 3D discrete element model of a Highwall panel has been prepared incorporating the presence of jointed overburden ...

Pillar Extraction | SpringerLink
Pillar extraction, (also referred to as retreat mining; pillar recovery; stooping; pillar robbing; and bord and pillar second workings) is the practice of forming a series of pillars and then partially or totally extracting some or all of the pillars, usually with mining operations retreating out of a panel. There are a number of basic pillar extraction …
Mining of new waste disposal panel begins at WIPP
Mining at WIPP is timed so that a panel is only ready when it is needed for waste emplacement. This is because the natural movement of salt causes mined openings to close. In fact, panels are mined slightly larger than the desired size to account for this closure. This salt rock behavior will eventually permanently encapsulate the waste.
