Sealing of Abandoned Areas

MSHA's standards for sealing abandoned areas in underground coal mines includes requirements covering the design and construction of new seals and the maintenance and repair of all seals. Records that will be collected under this rule will help assure that the construction and maintenance of seals are done correctly; certified persons conducting sampling in sealed areas are adequately trained; and results from sampling in sealed areas are recorded, so that problems can be found and fixed.
