There are many things that can be done to improve airflow in the mine. What is needed is to look around, inquire, measure and understand. Actions to dilute contaminants and improve the working environment will result in a healthier, happier workforce and most likely improved production and lower turnover. This paper has discussed some ways to find extra usable air when there is no extra ventilation capacity. If there is adequate air, then the option is to implement some of these changes and reduce expenditures through lowering operating costs. Since airflow power is proportional to velocity cubed (Marx 2008) the first fan blade setting reduction is the biggest savings. Don't forget, each cfm saved doesn't have to be heated or cooled either (Hall 1985). Remember to take the entire system into account. Develop and utilize a good computer model. All changes have consequences, so be sure to perform a risk analysis and determine the effects on emergency and evacuation planning.
