Reclamation of Abandoned Deep Mine Entries
Over 1,000 abandoned coal mine entries such as shafts, slopes, and drifts exist in the Eastern Coal Provinces of the United States. The paper discusses recent Office of Surface Mining case histories of hazardous shaft reclamation. Shaft collapse and characteristics of impending collapse can result from construction, mining techniques, or geologic factors. Six modes of failure are identified. Reclamation should begin with an exploratory/investigatory study defining site conditions, failure modes, and potential zones of instability. A hazardous shaft checklist recommending such items as current closure; shaft construction; borehole television inspection; site topography and geology; and specific analysis of methane, shaft depth and water level, surface water drainage, and closest mine pool monitoring site is presented. The site investigation should result in a site engineering study including abatement activities and consideration of safety requirements. Construction methods should be operated from stable ground with surface loading and equipment vibrations kept at a minimum.
