In 1955, the VNIMI team, in the work of which the author was directly involved, surveyed 70 of the most disturbed mine shafts in Donbass. For the remaining shafts, questionnaires on the condition of the shafts were collected with the corresponding graphic materials attached. The survey covered almost all natural conditions in which there are mine shafts of Donbass with the depth of more than 300 m.
