New Methods for More Efficient Use of Ventilation Air

• Description:
  A sufficient and constant supply of fresh air is essential to the health and safety of underground miners. This often requires elaborate ventilation systems that are costly in terms of equipment and man-hours. Moreover, these systems are relatively inefficient since 60 to 80 pct of the fresh air entering a mine often leaks into return airways, never reaching the working sections of the mine. In addition, much of the air that reaches the working section often short circuits out and never reaches the working face. The U.S. Bureau of Mines has developed some new and unique methods to help combat this inefficient use of mine air. Ventilation efficiency can often be improved by eliminating major leaks that occur most often at permanent stoppings. However, eliminating air leaks through every permanent stopping in a ventilation system would be an expensive and time-consuming operation. A more realistic approach is to measure the leakage across each suspected stopping and repair only those having a significant leakage. [Description provided by NIOSH]
