Geotechnical properties of Kentucky`s AML landslides and slope failure evaluation

A large body of geotechnical data, obtained from the U.S. Office of Surface Mining Reclamation and Enforcement (OSM) and the Kentucky Division of Abandoned Lands, is analyzed in this paper. The analysis includes causes of subsurface failures, phreatic levels, soil profiles, and soil composition data. Soil properties calculated from laboratory procedures and stability analysis techniques were also reviewed. Employing prudent engineering practices and parameters, seven failed slopes were subjected to back analysis for estimating realistic factors of safety. Important factors affecting landslides in eastern Kentucky are presented with appropriate examples.
