Mining vehicles a ride through time Mining Technology

It is unclear exactly when the first continuous mining vehicle was developed. The English Channel Machine built in the 1870s and ran on compressed air could possibly be counted, but most agree that the technology was first used in mining in the early 1900s. In 1912, for example, the Hoadley Knight Machine was developed for mining coal.
