A Comparison of the Effects of Various Soil Handling Equipment on the Density of Prime-farmland Subsoils.
NTIS: PB/85-241016 :269 pages
The primary objective of this study is to evaluate the influences of different equipment systems on prime farmland subsoil compaction due to surface mining in the Midwest. The basis for this research effort centers on four major experiment designs: (1) comparison of soil bulk density values for three distinct equipment systems (i.e., scraper, bucket-wheel excavator, and end-dump haulback) evaluated on the same general soil types; (2) evaluation of the effects of soil replacement in repeated lifts using scrapers; (3) presentation of bulk density values representing soil compaction for four equipment systems (i.e., bucket-wheel excavator, dragline, scraper, and end- dump haulback) on four separate minesites in the Midwest; and (4) development of a prediction analysis model for subsoil bulk density following reclamation based on equipment characteristics and a statistical evaluation of texture.
