Smart Cutting Drum

In a new research project supported by the Federal Ministry for Economic Affairs and Energy (BMWi) and in close collaboration with KRUMMENAUER Anlagenbau GmbH and CAE Software and Systems GmbH, the Institute for Advanced Mining Technologies (AMT) at RWTH Aachen is developing a newly designed smart cutting drum with integrated sensors for real time material … Continue reading Smart Cutting Drum

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.

Acoustic Fingerprint on Rock Cutting Machines and Their Implications for Excavation

In terms of safety and economic efficiency, the automation of underground extraction machinery is one of the most significant goals in mining. One major challenge in rock cutting is to adapt process parameters to variable rock conditions. The guidance of such extraction machines today is still dependent on an experienced machine operator who particularly listens … Continue reading Acoustic Fingerprint on Rock Cutting Machines and Their Implications for Excavation

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?!
