The caving zone is a potential underground storage of greenhouse gases. Therefore, the time–space relationship of caving zone compaction characteristics in the goaf has become an area for research focus in recent years; in this study, the formation, height determination, and compaction characteristics of a caving zone are examined.

Self-Compacting 3/4" stone - JLC-Online Forums
Apr 29, 2003· I have a question about 3/4" crushed stone. I read several places that 3/4" crushed stone is "self-compacting". That is, you dump it in a trech (as in under a concrete footing or floor) and you don't have to compact it with a plate compactor - it is already as "compacted" as it needs to be.

Decomposed granite - Wikipedia
Decomposed granite is rock of granitic origin that has weathered to the point that it readily fractures into smaller pieces of weak rock. Further weathering produces rock that easily crumbles into mixtures of gravel-sized particles, sand, and silt-sized particles with some clay.Eventually, the gravel may break down to produce a mixture of silica sand, silt particles, and clay.
