Continuous underground mining of hard rock minerals
Mechanical Rock Excavation has been used in underground soft rock mining for coal and industry minerals during many years. But the technology has to be modified to be used in hard rock (>150 MPa compressive strength). Over the last few years promising technology improvements have been made and it is now time to build a demonstrator to evaluate the technology in a real application.
