Geevor Mine Gallery 2016: 2 This is the second gallery of images I took around the museum, When the sun is shining and the weather is warm, there is just no better place to be.
Bob Orchard has supplied much of the information on the images.
The tank with “egg ends” is of riveted construction was originally an air receiver at the mine. But it was condemned for use as a pressure vessel.
So typical of Geevor it was moved and converted to a water storage tank. This type of construction goes back to Trevithick’s day.
Next to the Compressor house is the Electrical Sub Station. The mine was fed electricity from the large sub station at Trewellard which was built during the 1970’s. An underground cable carried the power to the transformers outside.
The next few images on the page are all taken in the interior of the Geevor Mine Compressor House. This was where the compressed air to drive the underground rockdrills and machinery was produced. Without this mining operations would have ground to a halt.
The building was constructed during the early 1950’s the three compressors were installed soon afterwards. The machines here are “Sentinal” double acting, two stage air compressors built by Alley & Maclellan Glasgow. The motors of the compressors are 3 phase, open frame “slip ring” motors, with wound rotors & starters.
When all three when all were running, the mine office windows would violently vibrate.
Victory shaft winder, is a suspended post brake / double drum winder. Built by the British Thomas Houston company. It was installed during 1954 by Bill Casley with assistance of others the chief engineer at the time being Bennett Wall.
At the front is one of two Lilly controllers. The driver will say that he drives the winder, but in reality the Lilly controls monitors what the winder driver is doing. If events move outside the parameters set by the Lilly, it will firstly alarm, then shut down the winder in a safe mode.
Not part of Geevor Mine this area at the bottom of the site belonged to the Levant Mine processing floors. Also the views from the cliffs are stunning.
I still have many images of Geevor that I have not printed yet. It is just a case of finding the time to get them done. I hope these pages have been interesting and enjoyable.
