Unconfined compressive strength data for rocks from TilTil and ElTeniente mines, Chile

Unconfined compressive strength data for rocks from TilTil and ElTeniente mines in Chile, plus basic index tests (porosity, density) and Elastic wave velocity for selected samples. Laboratory data collected as part of NERC grant NE/W00383X/1:Geological safety and optimisation in mining operations: towards a new understanding of fracture damage, heterogeneity and anisotropy.
