The objective of this project was to quantitatively assess the slope stability problems associated with coal surface mining in the eastern coal province and to recommend spoil placement techniques that provide for slope stability. Data were collected for 11 minesites in Alabama, Kentucky, Ohio, Pennsylvania, Tennessee, and West Virginia. A site was selected in each of the six states on which a detailed investigation was conducted. The investigations included drilling through the slide into solid ground beneath, collecting samples at various depths for identification, and for laboratory tests. A topographic survey and field monitoring was conducted to determine field conditions at each slide. It was concluded that there are numerous factors related to the geologic and topographic conditions within the region that contribute substantially to the problems of spoil stability. The most significant factor appears to be the steep topography of the areas being mined.
