Examples included the famous Morro Velho Mine in Brazil (1923) and experimental work in British coal mines (Hancock, 1926). Air cooling techniques in mining gained further recognition in the 1930s including their utilization in the gold mines of South Africa and in the Kolar Goldfields of India. However, it was the 1960s that saw the the start ...

High Pressure Door Systems. Most mines work on a partitioned ventilation system. In a partitioned system, different areas are sealed off from one another, meaning that risks such as noxious gas buildup can be localized. This helps minimize risk and maximize control throughout the entire mining area.

Atkinson resistance is commonly used in mine ventilation to characterise the resistance to airflow of a duct of irregular size and shape, such as a mine roadway. It has the symbol and is used in the square law for pressure drop, = where (in English units) . is pressure drop (pounds per square foot), is the air density in the duct (pounds per cubic foot),; is the standard air density ( ...
