A cave-in is a collapse of a geologic formation, mine or structure which may occur during mining, tunneling, or steep-walled excavation such as trenching. Geologic structures prone to spontaneous cave-ins include alvar, tsingy and other limestone formations, but can also include lava tubes and a variety of other subsurface rock formations. Glacier caves and other ice formations are very prone to collapse from exposure to warm temperatures or running water.
In mining, the term roof fall
Geological formations
- Alvar structures such as on the Stora Alvaret, Öland, Sweden
- Karst limestone such as in the Madagascar dry deciduous forests
