The usual method of disposing of this excess soil and rock is to place it in engineered earthen and rock structures known as excess spoil disposal areas or colloquially known as head-of-hollow fills, hollow fills or valley fills. In some cases underground mining also produces enough spoil to require the construction of valley fills.

Excess Spoil Fills When coal is mined by surface mining methods, rock and soil that overlie the coal must be first temporarily removed and stored outside of the immediate mining area. The rock is blasted as it is removed. The angular blast rock, or “spoil,” incorporates voids and therefore is less dense than undisturbed rock.
