It is important to have reliable prediction methods for mechanical excavation tools. I.e. when pre-damage methods like high-power microwaves, lasers, water jets or others are applied theoretical investigations on the possible improvements are inevitable. Montanuniversitaet Leoben performed two different studies on the subject (one for roadheaders, one for full-face tunnel boring machines). See the abstracts … Continue reading How to improve mechanical hard rock excavation?
RWTH takes on Chairposition for EUREG The Institute for Advanced Mining Technologies (AMT) at RWTH Aachen University was selected to chair the European Rock Extraction Research Group. EUREG for short, this group constitutes an informal reserch network currently consisting of four universities: RWTH Aachen University, TU Bergakademie Freiberg, TU Clausthal und Montanuniversität Leoben. The objective … Continue reading Sensor Technology for Automation in Mining and Tunneling
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.
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
