Methods to improve efficiency of mine ventilation systems

Mine ventilation air is a costly commodity, especially by the time it has been heated or cooled and moved to the bottom of the shaft and through the mine airways. Modifications that result in surplus mine ventilation air could bring financial and environmental benefits. Some issues mine operators have needed to address recently are increased airflow requirements to dilute diesel particulates

Methods to Improve Efficiency of Mine Ventilation Systems

improve mine airlow are shop ventilation methods, auxiliary equipment areas, dedicated intakes and returns, optimizing mine development, examination of mine airway utilization and alternative ventilation methods. Underground shops First, examine what is being done with the underground shop air. If it is being coursed directly to the returns, there may be potential to better utilize this

Development Of Coal Mine Face Ventilation

During the 20th century, the increased emphasis on worker health and safety and the advent of new mining equipment and methods led to many changes in mine face ventilation practices. Efforts by government and private industry to improve and modify ventilation practices resulted in better health and safety conditions for workers. This article focuses on U.S. Bureau of Mines (USBM) and National

Using Mine Planning and Other Techniques to Improve

(NIOSH) has conducted research to improve the ventilation of large-opening mines. The research has demonstrated that the ventilation of large-opening mines improves significantly by including ventilation requirements in the mine planning process and implementing some practical techniques during mining. Planning the location of long pillars to reduce the number of crosscuts between intake

Improving Ventilation in Underground Stone Mines

stone mine ventilation projects underway, but in the meantime a good information resource is the work done by the U.S. Bureau of Mines in the 70s and 80’s on ventilation for oil shale mines. The Bureau conducted this research because oil shale mines were projected to be gassy and would, therefore, require a lot ofven- tilation air. The focus of rhis oil shale work was on the use of jet fans

MINE VENTILATION SYSTEMS

MINE VENTILATION SYSTEMS Ventilation is the control of air movement, its amount, and direction. Although it contributes noth ing directly to the production phase of an operation, the lack of proper ventilation often will cause lower worker efficiency and decreased productivity, increased accident rates, and absenteeism. Air is necessary not only for breathing but also to disperse chemical
