Gas Control Introduction underground COAL

Gas Control. Some mines do not have a gas problem of any type, the quantity of gas in the coal being so low that only small percentages (or even zero) are ever detected in the air. In such mines, other than continuously or regularly checking gas levels to ensure conditions have not changed, no special processes are required.
