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 inproduction 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.
