The importance of research on alternative and hybrid rock extraction methods

With the increasing complexity of currently mined deposits, their depth and the long lead up time to first prodcution, and many more ecologic and economic factors traditonal mining methods come to their limits. There is a strong need to shift current economic boarders of excavation of raw materials. New, alternative fragmentation concepts play a very impottant role in this future development.

Activated rock excavation machines – vision or fiction?!

Mechanical rock excavation processes ensure an almost continuous extraction process when extraction, loading and transport can be combined into a single process. Over the past decades a lot of reserach was carried out to improve excavation technologies by a so-called activation of excavation processes e.g. by high pressure water jets or through an activation of … Continue reading Activated rock excavation machines – vision or fiction?!
