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

Experimental Study on Microwave Assisted Hard Rock Cutting of Granite

This paper describes the influence of high-power microwave irradiation on the forces needed to cut granite with a conical pick. Granite samples have been irradiated with 24 kW at 2450 MHz with an open ended waveguide. The effect of microwave treatment was assessed by linear cutting tests with a conical pick. Microwave irradiation lead to … Continue reading Experimental Study on Microwave Assisted Hard Rock Cutting of Granite
