Soil swell factor. As soil is dug up, it loses its compact structure and expands. This increase in volume can add 20-30% or more, depending on the soil type. Use this formula to estimate the expanded volume: Formula: Initial soil quantity (cubic yards) × Swell Factor = Loose Volume. Bulking factor for transport. When soil is hauled away, its ...

Swell Factor Calculator
The swell factor is a percentage that represents the increase in volume that occurs when material is excavated from its natural state in the ground, known as bank state, to a looser state. This factor is crucial for construction and mining projects to estimate the volume of material that needs to be moved or processed after excavation.

Effects of clay content, cement and mineral composition characteristics
During the drilling process, the increasing bulk volume and expansion pressure of the rock, caused by the swelling and hydration clays, have a high probability of a wellbore shrinkage, an influx of solids, and even a wellbore collapse (Cheatham, 1984; Wu et al., 2018).As a very common constituent of the clastic rock, the clay content can vary from 0 vol% to 66 …

The factors to consider are: Rock type or lithology: including grain structure and the propensity of a rock to disaggregate during excavation. The lower the disaggregation the greater the likelihood is of excavated material being poorly sorted with a relatively high bulking factor compared to material that is more disaggregated and better sorted.

I can't get hyperlinks to work on HEF--the only clue I can give you is to do a Google Search for "Volume of Shot Rock", and look for the "Geotechnical Enginneering Handbook" link.

MINE 2504 Glossary
Swell factor refers to the amount that the volume of a block of material increases once it is removed from the ground. The block of material "swells" due to the fact that it breaks into smaller pieces. Before breakage, the block is consolidated; but after breakage, the pieces do not fit perfectly back together and so they take up more space.
