Abstract
The U. S. Bureau of Mines, with the cooperation of several state and federal agencies, prepared mine closure concepts for adits and shafts at the request of the National Park Service. Eleven "Closure Concepts" have been completed and 10 more are in preparation. The information includes description of the closure methods as well as suggestions for where they can be used and technical illustrations for construction. Multiple closure options, by type of mine opening, were prepared as one-page field guides to assist field personnel in determining the most appropriate closure method for a given field situation. The mine concepts completed include design information provided by the Colorado Mined land Reclamation Division, Montana Abandoned Mine Reclamation Bureau, National Park Service, and United Kingdom National Coal Board. Concepts available include adit backfill, bat gate, cable net closure, concrete block bulkhead, concrete bridge channels cap, concrete shaft cap, hollow-core shaft closure, native rock bulkhead, PUF shaft closure, riprap bulkhead, and shaft or slope backfill.
