Anemometers - Mining Artifacts

Mechanical anemometers are an instrument used to determine the volume of air entering or exiting mine workings. They were invented by Benjamin Biram, house steward to the Earl Fitzwilliam, owner of numerous collieries in South Yorkshire, England, in 1844. The formula used most often in mine ventilation using an anemometer was q=av, in which q ...

Vernon was equipped with an anemometer, raw plugs, a raw plug tool, a hammer and extension string, the tools of his trade. One Friday he was returning to the pit bottom, via the 4’s seam, when he heard a gurgling sound, followed by a muffled roar. Vernon ignored a golden rule of the mining industry: “Thou shalt not run in a coal mine!”, and raced towards the underground office at the bottom of the shaft.
