The objective of this study was to develop data on the erodibility and size distribution of eroded sediment from mine spoil and reconstructed topsoils and subsoils typical of western Kentucky surface mined lands. Standard erosion plots were constructed of shale, subsoil, and topsoil at the alston surface mine of Peabody Coal Company. Rainfall was developed using a plot-sized rainfall simulator. Each plot was evaluated under tilled and compacted conditions. One compacted condition was developed with a wheeled compactor and another with a dozer and scraper pan. Runoff, sediment yield, and size distribution data were collected for each plot. Complete descriptions of each plot and the test apparatus and instrumentation are given. A discussion of the experimental procedures and data analysis procedures are included, and the results and conclusions are summarized.
