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

Alternative rock-cutting lab at Montanuniversitaet Leoben

The Chair of Mining engineering at Montanuniversitaet Leoben has a strong focus on alternative rock fragmentation technologies. The major focus lies on high-power microwave irradiation for pre-conditioning hard rocks prior to mechanical excavation. The available laboratory infrastructure consists of a 30 kW microwave fracturing apparatus, fully equipped rock mechanics and micro-analytical laboratories and extended computer infrastructure … Continue reading Alternative rock-cutting lab at Montanuniversitaet Leoben
