(1923) and experimental work in British coal mines (Hancock, 1926). Air cooling techniques in mining gained further recognition in the 1930's including their utilization in the gold mines of South Africa and in the Kolar Goldfields of India. However, it was the 1960's that saw the start of a real escalation of installed mine cooling capacity.

Welcome to Debon Air Compressors

At 5pm on Friday afternoon my 75kw air compressor tripped the power. We phoned around and no one was willing to come out to assist us right away. One of my friends suggested that I try Debon Air. They were so helpful and said that they will bring out a rental compressor in order to get things running again. It was up and running within 1.5 hours.

Compressed Air | Introduction | underground COALTraduire cette page

The majority of mines reticulate compressed air from surface compressors in steel pipes, frequently suspended alongside the water supply lines. Occasionally underground compressors are used which reduces the need for an extensive pipe system and the amount of leakage, but also restricts the availability. Underground compressors are also prone to be fire hazards if not very well maintained.
