In a showcase of machines that make mincemeat of the earth's toughest rocks, we see how almost two miles underground in the Kidd mine in Canada, the mighty ITH drill is being used to enable the extraction of copper and zinc; in Finland, the Jumbo Tunneller is boring through granite to excavate a new metro tunnel to improve Helsinki's commuter services; and deep beneath the Cheshire countryside, a continuous mining machine is working round the clock to keep Britain's transport network moving.

    I usually love programs like this but the narrator kills this one. He's way too over the top, has been the entire series
