Recent advancements in rock cutting and tunnel boring machine (TBM) performance have underscored the importance of optimising cutter design, operational parameters and understanding rock fracture ...

Rock cutting and sawing performance analysis encompasses a multidisciplinary approach that integrates advancements in mechanical engineering, material science, and computational modelling to optimise ...

On the eastern side of the Great Pyramid lies a basalt floor so precisely carved it raises more questions than answers. Could this be evidence of lost technology beyond the reach of tools known to ...

On the banks of the Columbia River, tall columns of rock poke out from the cliffs. “So you see all of these black rocks that are on either side of us, on either side of the river? Those are basalts.

Spreading crushed basalt on cropland and using special fertilisers that stop nitrogen loss could cut global agricultural emissions of a potent planet-warming gas by 25 per cent. Nitrous oxide is a ...
