The document discusses the importance of ventilation systems in underground mines, aimed at ensuring safe air quality for workers by diluting contaminants and managing temperature. It outlines various lectures covering pollutants, air requirements, ventilation laws, and fans. Additionally, it references multiple authoritative sources on mine ventilation and its planning.

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.
