Understanding why and how rocks fail under various conditions is absolutely crucial to understanding earthquakes, roof collapse in mines, hydraulic and gas fracturing processes, etc. Large sample dimensions enhance the resolution of detailed acoustic emission studies. Microseismological studies are made possible with increased sample dimensions. Furthermore, the physical dimensions permit numerous simultaneous studies which together provide rigid constraints on the physics of rock failure.
