| Near the surface of the Earth, for changes in altitude of several hundred meters, it can be roughly assumed that when rising by 10 m, atmospheric pressure decreases by 1 mm Hg. Art., and when descending by 10 m – decreases by 1 mm Hg. Art.
Descent into the mine by 100 m corresponds to ten descents of 10 m, which means the atmospheric pressure will increase by 10 mm Hg. Art. and will be 752 + 10 = 762 mm Hg. Art.
