Machine performance and Acoustic fingerprints of cutting and drilling

‘It is always dark ahead of the pick!’ This centuries-old miners’ expression reveals the still persisting uncertainty about rock properties during exploration and extraction processes. It is still difficult to predict what a drill rig or a cutting machine will encounter during operation. Therefore, during the RealTime Mining project different sensors or sensor combinations were … Continue reading Machine performance and Acoustic fingerprints of cutting and drilling

Pre-weakening of hard rock with waterjet – potential breakthrough solution for hard rock cutting

The pre-weakening of a rock mass prior to the cutting process could lead to a breakthrough solution for hard rock cutting. Once feasible it could be the key to developing continuous mining methods for base and precious metals that are currently predominantly mined using drill and blast. At RWTH Aachen University Rock Cutting Center hard … Continue reading Pre-weakening of hard rock with waterjet – potential breakthrough solution for hard rock cutting

The RockCutting Center at the Institute for Advanced Mining Technologies (AMT)

The work group RockCutting of the Institute for Advanced Mining Technologies (AMT) does research in the field of mechanical extraction of resources and investigates the main variables affecting the extraction process and describes these in a model. An extensive need of research results especially from developments in power transmission and sensor technology.
