Mine Ventilation Systems

Mine Ventilation Systems Practical Mine Ventilation Engineering to be Published by Intertec Puslishing Co. 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

Air travels from the surface through the mine to this low pressure point. Airflow in a mine is induced by pressure differences between intake and exhaust openings. The pressure difference is caused by imposing some form of pressure at one point or a

17/10/2017· Types of Mine Ventilation Systems Two basic types of ventilation systems include homotropal and antitropial systems. Homotropal systems allow for the airflow within the mine to be transported in the same direction as the fresh air, whereas antitropal systems remove contaminated air in the opposite direction of fresh air entering the mine.

A mine ventilation system is used for the circulation of adequate quality and quantity of air in mines. These systems include airways, fans and control devices to restrict or direct air flow, filter the air and systems for monitoring air quantity and quality. Mine ventilation systems are more commonly used in closed mines than open mines.

In metal mines leakage in mine ventilation systems can average out to 25%. However, leakages not in excess of 15% are attainable with good ventilation practice. Ventilation Planning For Various Mining Methods The physical outline of the ventilation system depends largely on the mining methods in use to extract ore from the mineral deposits. Each type of metal and

done to make the best use of ventilation systems. Should there be surplus air, in which some of these options may result - financial and other benefits can be obtained. Some of the issues mine operators have needed to address recently are increased airflow requirements to dilute diesel particulates in metal and non-metal mines. Also, operations are faced with demands from

Correct design, implementation and maintenance of mine ventilation is therefore of fundamental importance. In present day mining, ventilation systems designed and operated to maintain efficient operations will normally enable a high standard of occupational health and safety to be achieved.
