This seal, constructed according to MSHA require- ments, will be of a permanent nature to prevent access by people and animals and will be impermeable to prevent flow of water from the mine. The sealed mine entry will then be backfilled and reclaimed at the surface. • See Insert Page L1-3a 2.2 PREPARATION FOR BACKFILLING After mining has ceased, all drill holes and adits will be sealed and covered in accordance with accepted procedures and all buildings will be dismantled and removed.
