Oxygen


  • GENERAL PROPERTY:-

  1. It is colorless, tasteless,.
  2. Specific Gravity = 1.1047;which is heavier then that of air.
  3. Critical Temp. = -119°C
  4. Oxygen can cause dangerous condition in mine only by its absence.
  5. 100 volume of water at room temp. consume 3 volume of oxygen.
  6. In any mines,oxygen should be 19% or more(for India) & 19.5% or more (for USA)
  • USES OF OXYGEN IN MINES:-

  1. Breathing by person.
  2. Slow oxidation of coal or other carbonaceous material.
  3. Burning of F.S.L. (Flame Safety Lamp) and for non-coal mine by acetylene lamp.
  4. Decay of material, timber by fungus growth.

Deficiency of Oxygen

O2 Conc. Effects
19% Flame height on F.S.L gets reduced by 50%
17% Noticeable increase in rate of breathing
15% Spinning sensation in head & increased heartbeat
13-9% Distortion, fainting, vomiting sensation, headache, blue lips and coma may occur
7% Coma, Convulsions (Violent uncontrollable contraction of muscles) or death may occur
Below 6% The condition may eventually lead to death.
