2. Ventilation
1) Background
•The main objective of an underground mine ventilation system is clear:
 to provide air flows in sufficient quantity and quality to dilute
contaminants to safe amounts/concentrations where personnel are
required to travel and work.
 To Supply of oxygen men and machines;
 To Dilute toxic gas / explosive and dust originated in
production operations;
 To Assist in temperature control and humidity.
• This requirement is integrated into the mining law of those nations who possess that type of legislation.
• The degree of "quality' and "quantity" varies with regulations set from nation to nation, depending on a
number of parameters: mining history, contaminants of greatest concern, the apparent dangers
associated with those hazards and the political/social structure of the nation.
• The general requirement is for any personnel to work and travel in an environment that is safe and
comfortable.
