FIELD: mining, particularly to protect objects to be developed and located in shifting basing against flooding with ground and surface water. ^ SUBSTANCE: method involves forming water-receiving excavations made as drains, pits or wells; draining and removing water; predicting ground surface relied after ground deformation before underground work performing; marking out flat shifting basin bottom and zone characterized by maximal relief depression; forming pit in area of maximal relief depression; arranging water drain at shifting basin boundary; forming ground water removing wells. Pit volume, well depth and well pitch are determined from mathematical relations. ^ EFFECT: increased efficiency. |
