Abstract
This report includes summaries of existing legislation pertaining to outcrop barriers and state-of-the-art survey of outcrop barrier designs and related mine closure techniques. Six sites were inspected in the field and are presented as case histories. The data analysis presented includes a computer-modeled seepage analysis, an overburden blow-out analysis, and a wedge stability analysis. The results of these analyses are interpreted to form recommendations for coal outcrop barriers that will minimize seepage and the potential for failure. Supplementary support and reinforcement alternatives are also discussed.
