Boart Lena's first machines for KGHM, to operate in areas of roof height down to 2 m, were the Face Master 2.0 drill jumbo
and the Roof Master 2.0 bolter, manufactured in cooperation with J.H.
As part of the purchase contract, Atlas Copco Chilena provided one drill jumbo
technician and one Wagner Scooptram technician in the first months that the machines were at the mine, providing maintenance support and operator training.
The world's first fully-operational computerised underground drill jumbo
was introduced by Tamrock in 1985 and new generations have been brought on to the market since.
