Battering Ram - Use in Mining

Use in Mining

Pliny the Elder in his Naturalis Historia describes a battering ram used in mining, where hard rock needed to be broken down to release the ore. The pole possessed a metal tip weighing 150 pounds, so the whole device will have weighed at least twice as much in order to preserve its balance. Whether or not it was supported by being suspended with ropes from a frame remains unknown, but very likely given its total weight. Such devices were used during coal mining in the 19th century in Great Britain before the widespread use of explosives, which were expensive and dangerous to use in practice.
